If a planet has an obliquity of 180 degrees that means it rotates?

It rotates in the "retrograde" direction.
"Obliquity" is another way of talking about the tilt of a planet's axis.
You might say the planet is "upside down".
The direction of the rotation is called "retrograde" ("backwards" compared with the Earth's rotation).
Note: there is a complication here about how astronomers define the North pole of a planet, but that's probably an unnecessary complication for most people.

"upside down" compared to the usual situation.
That means it has RETROGRADE ROTATION.
(Note: Strictly speaking it's not quite as simple as that, but I'm pretty sure that's the answer this question requires.)

Which planet spins like a bowling ball?
because its axis is tilted
What planet is tilted 98 degrees?
Uranus. However, one annoying fact is that Uranus's axis is tilted 98 degrees to its plane of rotation. This means that its so-called north pole is actually directed more closely to what we would call "south" in the solar system than to "north." So arguably, Uranus's rotation is opposite to the rotation of all the other planets (except for Venus), but apparently astronomers don't choose to define it that way. So instead of saying that Uranus is tilted 82 degrees and rotates backwards, they say that it is tilted 98 degrees and rotates forward
What planet moves around the sun in elliptical orbit and rotates only once in 59 days?
You are probably thinking of Mercury which revolves around the Sun in 59 days. The word 'rotate' means turning on its axis. We call that a day. The Earth rotates in one day or 24 hours. Mercury rotates (its day) in 176 Earth days. Mercury is really interesting because its day is almost 3 Mercury Years long.
An inner planet it rotates once every 24 h and revolves around the sun once every 365 days?
Venus rotates once every 243 Earth days-by far the slowest rotation...of about 24 HOURS!
How many degrees will earth now rotate in a solar day?
You are a clever questioner, indeed. You have asked a subtle and interesting question. You probably know that there are at least two distinct answers to the question, because there are two different kinds of day. The sidereal day is the period during which earth rotates 360 degrees relative to the distant stars (not the sun). If you were far above the solar system looking down on earth from the north, you would see that earth rotates a full 360 degrees relative to the stars, but still has to rotate a little more to reach the starting point relative to the sun, because we orbit the sun, this complicates things a little bit. So in a sidereal day, the earth rotates exactly 360 degrees, but this day lasts only 23 hours 56 minutes and 4.1 seconds, roughly. The synodic day is the period during which earth rotates one time relative to the sun. This rotation will be slightly more than 360 degrees, because as explained above the earth has to rotate a little extra (beyond a full 360 degrees) in order to reach the starting point relative to the sun. This is the day as we typically experience it. So if you are asking about the earth's rotation during a synodic day, the rotation is closer to an average of 360.9856 degrees per day. Another way to look at this is to consider the earth's coordinate system. There are 360 degrees of longitude. It is possible to consider the earth's degrees of longitude as the basis of your measurement, so that you can say the earth rotates 360 degrees of longitude relative to the sun on average each day, even though the absolute rotation of the earth is closer to 360.9856 degrees on average.
What planet is tilted on its side and rotates around the sun?
This must be Uranus. "On its side" isn't a very scientific way of putting it. It means that the planet's axis is tilted at about 90 degrees (98 degrees actually) from the perpendicular to its orbital plane.
A planet has a very long day compared with earth .What does that tell you about the movement of that planet?
It means the planet rotates slower. To be precise, the angular velocity is less.
What does Venus do that no ether planet does?
It has retrograde rotation which means it rotates in the opposite direction of all the other planets.
Which planet appears to spin on its side?
Uranus spins on a 97 degree angle or on its side.
Which planet has its rotation axis tlted towards its axis?
How can a planet have it's axis tilted towards it's own axis? I think you are refering to Uranus which has an obliquity of 98o which means it's basically rotating on it's side and it's "north" pole points towards the Sun.
What shape is the planet Venus and does it have an axis?
Venus is nearly a perfect sphere. It rotates very slowly, but it does rotate. That means it does have an axis of rotation.
What is Venus rotation?
The axis of Venus is tilted 177.3 degrees from the plane of the ecliptic. This means that Venus rotates clockwise, instead of counter-clockwise, as viewed from the direction of Polaris. Its period of rotation is -243 days, making it the slowest rotating planet in the Solar System.
What planet orbits the sun on it's side?
With an axial tilt of about 98 degrees (compared to the Earth's 23.4), Uranus appears to be lying on its side.
Does Neptune rotate vertically or horizontally?
yes because all planets rotate.stupid people.
What planet has longer days than planet year?
Venus. The day is very long - 243 Earth days, and it's year (it's orbital period to travel once around the sun) is 225 Earth days, which makes a day on Venus longer than it's year! Interestingly, this planet rotates in "retrograde motion" which means that it rotates in the opposite direction that Earth does. This means that on Venus, the the sun rises in the west and sets in the east!
What does -243 Earth days rotation of planet Venus mean?
It means that Venus rotates oncefor every243 days on Earth. The minus sign is to show that Venus rotates in the opposite direction from Earth. Venus rotates in aclockwise direction(seen from an imaginary placehigh above the Earth's north pole).
What is the motion of Uranus?
It takes 84.02 Earth years (sidereal years) to orbit the sun. And the rotation of Uranus on its axis it takes 17 hours, 14 minutes, and 24 seconds.
