Venus Does Not Rotate Around Its Axis.

Venus Doe Not Rotate Around Its Axis​

Venus has stopped its axial rotation; now it does not rotate around itself; one face of Venus is always facing the Sun, which will have a lasting day-light, and the other face has always the darkness of night. This is called the Last Day: the day which will not be followed by another day.
This is like our Moon; it does not rotate around itself, but only it rotates around the Earth; one face of Moon is always facing the Earth, while the other side is unseen by us on Earth.

Example:
This will be like a father [: the Earth] playing with his child [: the Moon]; the father stands in his place, holding both hands [: the gravity] of his child, and drags his child round about himself. Therefore, the child rotates around his father, but does not rotate around himself. The child always faces his father who sees the face of his child, but does not see his back. This is an imaginary example.

Venus has suffered a serious and disastrous changes:
- the side facing the Sun has a lasting day, with extreme heat and high temperatures, so water evaporated and life has been exterminated there.
- The opposite side has a lasting night, with extreme coldness and freezing, and mostly life has exterminated there also.
- There are some other intermediate zones like the dawn and the afternoon zones, where temperature will be less extreme, but such zones are vulnerable to other dangers like the frequent falling of comets.
- The atmosphere of Venus has changed; it is now full of smoke and various poisonous and suffocating gases of the upper atmospheric layers like SO2 and other gases which have mixed with each other to form thick clouds of smoke.
- The water of seas and rivers has evaporated and vanished on the dayside. The other side may have iced and frozen. This region is also vulnerable to the falling of comets.

The same situation has occurred on Mercury before Venus, and the same fate will be of our Earth, when it will stop its axial rotation.

Why any planet rotates around its axis: That is because of the heat of its core; i.e. the energy derived from its central heat is the driving factor of the planet causing it to rotate around itself; so that its axial rotation is fast if it is very hot, and will be slow when its central heat is not very hot. Earth will lose its heat by radiation and eruption of volcanoes until it will gradually slow down then stop its rotation around itself.

Aw jeez, there you go again with more ignorant nonsense. The moon and Venus do so both rotate around their axes. Venus rotates once every 243 earth days in a retrogade direction, slightly longer than the time it takes it to make one orbit of the sun, and the moon rotates once for every orbit of the earth so it always presents the same face to us.

You're getting a little tiresome, making empirical claims that aren't true in a science forum and trying to draw religious conclusions from them.

Venus has stopped its axial rotation.

Sinister said: "The moon and Venus do so both rotate around their axes. Venus rotates once every 243 earth days in a retrogade direction, slightly longer than the time it takes it to make one orbit of the sun, and the moon rotates once for every orbit of the earth so it always presents the same face to us."
I say: They say so; but it is unreasonable; think deeply about the subject; it is more logical that Venus, as is our Moon, do not rotate around themselves, but Venus rotates around Sun, and Moon around Earth. Refer to the explanatory example in our article and more details at our website, eventhogh it appears different from some Astronomical subjects considered at present as certain facts.
See also the strange findings in the atmosphere of Venus, that they have now no explanation to them.
Don't you know that the day on Earth is getting longer gradually? As its heat decreases and it is getting cooler by time due to to the radiation and the eruption of volcanoes and other factors?
With best regards.

So how does the heat in the planet's core make it rotate around itself? When you put an iron ball in the oven for a while, it doesn't rotate by itself. You make a ball(a cold one especially) rotate with your hand(a force from outside), it rotates, the friction slows it down though.

Empirical facts are not a matter of opinion. Venus and the moon both rotate on their axes, and the fact that you don't understand that and think it's unreasonable doesn't enter into it. That's what the evidence shows, and I'd bet I've thought far more deeply about this subject and have a better understanding of it than you have. Imagine you're standing on the surface of the moon when it's full. The reason it's full, from our perspective down here on earth, is that it's directly facing the sun so its whole face is illuminated, and you on the surface of the moon will also be directly facing the sun. The earth will be dark on the side you can see, because it's between you and the sun. Now imagine standing on the surface of the moon, in the same place, at the new moon. The sun is now behind you, on the other side of the moon, and you'll see the earth as full, because the moon is now between the earth and the sun. You're looking in the opposite direction. How can you explain that except by noting that the moon has rotated 180 degrees with respect to the sun? The moon goes around the earth once in about 28 days, and rotates on its axis in the same time period. It's tidally locked to the earth so that we always see the same side of it, but that doesn't mean it's not rotating. You can do this experiment even more directly with a couple of small spheres, like tennis balls or baseballs. Let one be the earth, the other be the moon, and mark a spot on the latter one on the side facing the earth. Now move it around, but make sure that marked spot continues to face the one representing the earth. You'll have to rotate it for that to happen.

And yes, I know that the day on earth is getting longer, but that has nothing to do with the earth's internal temperature. It's tidal drag that's slowing down the earth's rotation, mostly due to the moon and the sun, not cooling. The web site you refer me to is mostly ignorant nonsense.

 

[eanassir]

Smilingfish, the iron ball here may be somewhat different than the Earth: the iron ball is under the influence of the Earth gravity, while the Earth is in the space, and eventhough it is under the effect of the Sun gravity, but it is on a certain distance from the Sun, that makes its gravity influence the Moon and keep it near the Earth rather than being attracted by the Sun.
God – be exalted – said in the Quran 36: 40

{لَا الشَّمْسُ يَنبَغِي لَهَا أَن تُدْرِكَ الْقَمَرَ وَلَا اللَّيْلُ سَابِقُ النَّهَارِ وَكُلٌّ فِي فَلَكٍ يَسْبَحُونَ} ​

The explanation: (It is not for the sun to overtake the moon, neither does the night outstrip the day; but each [of the sun, the moon and the earth] is swimming along into a [specific] orbit.)
The other difference is that the iron ball has a solid core, while the Earth has a very hot and semiliquid lava and imprisoned gases inside its core which try to get out, as sometimes occurs when the volcano erupts and othertimes the earthquakes take place.
These may be among the factors that cause the Earth to rotate around itself, while the Moon has a cold core, it does not rotate around itself.
So every hot object in the universe rotates around itself, and every cold object does not rotate; the speed of its rotation is relative to its internal heat and its mass.

Venus Doe Not Rotate Around Its Axis

It's Bush's fault!

 

[IdRatherBeSkiing]

The moon does rotate. If it did not rotate, we would see a different view of it each night. If you are truly interested in astronomy, I suggest you actually learn something about it. Citing religious texts is not learning astronomy.

 

[#juan]

I see I'm not the first but I had to reply to this crackpot nonsense.

Venus orbits the Sun at an average distance of about 108 million km, and completes an orbit every 224.65 days. Although all planetary orbits are elliptical, Venus is the closest to circular, with an eccentricity of less than 1%. When Venus lies between the Earth and the Sun, a position known as 'inferior conjunction', it makes the closest approach to Earth of any planet, lying at a distance of about 40 million km. The planet reaches inferior conjunction every 584 days, on average.
Venus rotates once every 243 days—by far the slowest rotation period of any of the major planets. A Venusian sidereal day thus lasts more than a Venusian year (243 versus 224.7 Earth days). However, the length of a solar day on Venus is significantly shorter than the sidereal day; to an observer on the surface of Venus the time from one sunrise to the next would be 116.75 days.[27] The Sun would appear to rise in the west and set in the east. At the equator, Venus' surface rotates at 6.5 km/h; on Earth, the rotation speed at the equator is about 1,600 km/h.

I just picked this out of Wicki but the info seems right.

 

[hermanntrude]

it IS right, Juan, but don't expect this troll to believe it. If it wasn't written by a holy man who didn't have the technology to detect the rotation by experiment, then it can't possibly be true.

 

[#juan]

Hey Herman, it gets better......

Have a look at his explanation of gravity. :roll:

 

[eanassir]

Dexter Sinister, I respect your Astronomical knowledge, and certainly you are more acquainted about Astronomy than I am; I will never claim that I am better than you. How can that be, when you are an Astronomer, having much experience in this field. But I cannot accept to be guided blindly by others; I should investigate and discern any idea. And why not if the correct idea confirms the Quran and the Bible?
Moreover, I do not claim that I know better than Astronomers; this will indeed be foolishness. I say what I am convinced about, and I have a great faith in God and His Glorious Quran that includes a large number of Quranic revelations pertaining to science; like the existence of life on Mars and some other planets, and an anticipated meeting between the people of Earth, and the people of Mars and some other planets.

About the Moon: it does not rotate around its axis, but rotates around the Earth with one face; the other face is unseen. The Sun will see all the sphere of the Moon ( its two faces) as it moves in its orbit around the Earth.
Therefore, the thing that has confounded the picture is that the Moon appears as if it rotates around itself in relation to the Sun; but in fact it does not rotate around its axis.
The example of the two balls, that you mentioned, can be used to explain the subject: Suppose that two balls of wood one resembling the Moon, and the other resembles the Earth, these two balls being fixed by a ruler with nails so that the Moon ball cannot rotate around itself, the axis of rotation is in the centre of the Earth ball, so when the Earth ball rotates around its axis, it drags the ruler and the Moon ball with it to rotate around the Earth ball; the Moon ball will not rotate around its axis.
Now, if there is a light globe in front of the two balls, then all the surface of the Moon ball will get the light gradually as it goes in its rotation around the Earth ball; so the Moon ball will appear as if it has rotated around itself in relation to the light globe, while in fact it does not rotate around itself because it is fixed by nails to the wood ruler and cannot rotate.
Moreover, the point selected let it be the point where the ruler is fixed to the Moon ball; this point will go round about the Earth ball, while the Moon ball does not rotate around its axis because it is fixed with nails to the ruler.
With best regards.

#Juan, you picked the informations from the Wicki, and the Wicki picked it from some present explanations; I say: think about the matter yourself, pick the data and consider the idea from the start, and don't dictate words from books and lectures. See the strange thing that they say about the day of Venus; it can be explained more plainly in case Venus does not rotate around itself. See also what has befallen the planet Venus: its atmosphere is full of clouds of thick smoke; its surface temperature suffers many serious findings.
See this quotation from the nineplanets site:http://www.nineplanets.org/venus.html
" the periods of Venus' rotation and of its orbit are synchronized such that it always presents the same face toward Earth when the two planets are at their closest approach. Whether this is a resonance effect or merely a coincidence is not known."

 

[eanassir]

IdRatherSkiing, see the example of the two wooden balls fixed to a ruler, that I have just posted to Dexter Sinister.

 

[karrie]

Moreover, the point selected let it be the point where the ruler is fixed to the Moon ball; this point will go round about the Earth ball, while the Moon ball does not rotate around its axis because it is fixed with nails to the ruler.
With best regards.

Where this explanation fails is in the fact that the moon is not stuck in one position around the earth. There is no nail dragging it along with earth from a set coordinate.​

 

[eanassir]

hermanntrude, "the technology to detect the rotation by experiment" that you mention and claim :
See this here: http://www.nineplanets.org/venus.html
" the periods of Venus' rotation and of its orbit are synchronized such that it always presents the same face toward Earth when the two planets are at their closest approach. Whether this is a resonance effect or merely a coincidence is not known."

[eanassir]

karrie, as you say the Moon is not stuck in one position around the Earth.

 

[IdRatherBeSkiing]

karrie, as you say the Moon is not stuck in one position around the Earth.

Which means the Earth is not dragging the moon around when it rotates. The only way for the moon to keep the same face toward the earth is by rotating on its axis. 1 rotation = 1 revolution.

 

[eanassir]

IdRatherSkiing, it does not mean so; refer to the example of the two wooden balls, where the ball resembling the Moon is fixed to the ruler by nails and screws. The Moon apparently rotates around itself in relation to the Sun, not the Earth; in fact it does not rotate around its axis.
