Yes. The reason for this is that all planets rotate, and if they rotate, then they must rotate about some axis. The cause of planetary rotation is a bit more complex. The origins of any planet begin in a nebula. Initially, the nebula is very large and has a very, very small amount of angular momentum (spin). As gravity begins to shrink the nebula, it spins faster and faster for the same reason a figure skater spins faster when he/she brings his/her arms closer. After the nebula flattens and forms and accretion disk and a star, the rest of the gas and dust clump together to form planets which still retain the original nebula's angular momentum, which causes them to spin. Since the nebula must have angular momentum in order for planets to form, all planets have angular momentum, and all planets rotate. If all planets rotate, then all of them must have an axis.
No, there are a variety of different tilts represented here in our own solar system. Earth has about a 23.5 degree tilt; Venus is tilted upside-down (i.e., it rotates opposite the direction it orbits) and Uranus rotates on its side at about 98 degrees to the plane of the ecliptic.
Yes. If you didn't know, the equator is an imaginary line - not some ring that just magically appeared.
Yes. If a planet happens not to be rotating in the sidereal sense, then it is rotating relative to its star. But for a planet, some form of rotation is inevitable.
No planet has lines of latitude or longitude, it is simply a cartographers convention on maps of the Earth.
Yes.
yes they do
Yes, all of the planets rotate around the sun, in the same direction but at different speeds and time periods. well planets rotate on their own axis, the correct term would be revolve. The planets revolve around the sun
Since the inner planets are composed mainly of rocks, they are heavier, and rotate slower.
ALL of the planets in our solar system have axial tilts. Jupiter and Venus have the least, while Uranus is most.
No. Not even all planets rotate in the same direction (Venus is retrograde; Uranus is sideways); the rotation of (much smaller) comets is essentially random.
All of the planets in the solar system rotate, but two are very slow. They are Mercury and Venus.
All of the planets in the Universe rotate on an axis. They all do.
Yes. All planets rotate about an axis.
no
All of them. A few satellites are tidally locked to their primary (luna for example), but all the planets rotate.
All the planets rotate on their axes and it would be a very unusual thing to find a planet that did not rotate.
No, all the planets, moons, asteroids and the sun do.
well they rotate on their axis as they orbit the sun
Yes, all of the planets rotate around the sun, in the same direction but at different speeds and time periods. well planets rotate on their own axis, the correct term would be revolve. The planets revolve around the sun

If you look at the entire solar system, all the planets, except Uranus, rotate in the same direction. If you call north up, then all planets rotate on that axis except for Uranus. Uranus spins on it's side in this model. While all the other planets spin on the North/South axis, Uranus spins on the East/West axis.
