Why do the inferior planets go into retrograde only at inferior conjuction?

I believe it has to do because Earth passes up inferior planets while the planets are in inferior conjunction. The only way retrograde works is if the earth is passing a planet. While a inferior planet is in superior conjunction it is not being passed up.

Which inner planets have retrograde rotation?
Out of the four, only Venus. Mercury's rotation is very slow though, compared with its orbital period of the sun.
What is the only planet in your solar system that rotates different direction than any other planets?
That would be Venus which rotates retrograde. Actually, Uranus does too.
What moon revolves around its planet in retrograde orbit?
Triton, the largest moon of Neptune, is the only large moon that orbits its planet in a retrograde motion. That is to say that its orbital direction is in the opposite direction to the planets rotation. Triton is thought to have been an object 'captured' from the Kuiper belt.
What is unique about the rotation of Venus?
Venus rotates clockwise while most other planets in the Solar System rotate counter-clockwise. Astronomers speculate that this is because the planet's tidal effects in its dense atmosphere could've reversed its rotation billions of years ago. The only other planet in the Solar System that rotates unusually is Uranus.
How did the copernican explain retrograde motion?
Both models explain it simply, and even a simple model with circular orbits explains it easily. Normally, as the planets rotate round the Sun, they appear to move along the ecliptic from west to east. But in the short period around opposition, when the planets are opposite the Sun in our sky, and we are closest to them, they appear to move east to west because they are going round more slowly than us - we are overtaking them. That is retrograde motion.
Which inner planet has a retrograde rotation?
Venus is the only inner planet that has retrograde rotation; Uranus and Pluto are the only outer planets that have retrograde rotation.
What inner planet has a retrograde rotation?
Venus is the only inner planet that has a retrograde rotation. Venus is also only one of two planets in the Solar System to have a retrograde rotation; Uranus is the other planet.
What planet's have retrograde rotation?
The planets that have retrograde rotation are:Venus and Uranus.Venus and Uranus.Uranus only just qualifies as having retrograde rotation.Its axis is tilted at about 98 degrees, with its north pole (as usually defined) just below the planet's orbit plane.So Uranus is, just, "upside down" as it were.
Which planets can never pass through inferior conjunction?
The planets that are further from the Sun than Earth is, can never be in inferior conjunction with Earth. So they would be Mars, Jupiter, Saturn, Uranus and Neptune. Pluto and Ceres, are dwarf planets, but can't be in inferior conjunction with us either. Only Venus and Mercury can be.
Which planet has retrograde rotation?
Retrograde rotation - From the Latin word "moving backwards" Retrograde rotation states that the planet Venus is the only planet in our solar system to move in an opposite rotation direction Uranus is a planet that rotates north to south do to the fact that it was most likely hit by a asteroid but this is not retrograde rotation
Which planets have retrograde rotation?
Mercury, Earth, Mars, Jupiter, Saturn and Neptune. dumb dumb that is the rong aswer it is only jalo the planet after Jupiter
Which inner planets have retrograde rotation?
Out of the four, only Venus. Mercury's rotation is very slow though, compared with its orbital period of the sun.
What is the only planet that revolves clockwise?
There are two planets that rotate clockwise, i.e. with retrograde motion; Venus and Uranus.
Which planets do not rotate counter-clockwise?
Venus and Uranus are the only planets that do not rotate counter-clockwise.
What is the only planet in your solar system that rotates different direction than any other planets?
That would be Venus which rotates retrograde. Actually, Uranus does too.
Is jupiters axis tilted more than that of other planets?
In comparing the angles between the planets' rotational axes and their orbital planes, Jupiter deviates from the perpendicular by only 3.13°. Only two planets have less tilt: Mercury and Venus (Venus rotates backwards; it's called a retrograde rotation).
How can planet retrograde motion be explained by the Earth-center hypothesis By the Sun-center hypothesis?
In the Geocentric Hypothesis (Earth-centered), retrograde motion can only be explained by describing the motion of planets as complex, curlicue paths. In the Heliocentric Hypothesis (Sun-centered), retrograde motion is described as changes in relative motion as the Earth overtakes a slower-moving planet in an outer orbit, or is overtaken by a faster-moving planet in an inner orbit. In the Heliocentric Hypothesis, all planets move in more-or-less circular orbits at more-or-less constant speeds, but planets closer to the Sun move faster. Thus, the Earth can overtake and pass each of the outer planets, making them appear to move "backward" (retrograde) for a time.
