The Kuiper Belt
Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.
Uranus rotates in its horizontal axis rather than on its vertical one, like the other planets in the solar system. Astronomers believe that an Earth-sized object collided with the planet in the distant plans and knocked it onto its side.
Pluto is not a planet, but it is a dog from Mickey Mouse. Pluto, is rather a dwarf planet, because it is not big enough to be a planet.
No. Io is a moon as it orbits the planet Jupiter rather than the sun.
Pluto is now classified as a dwarf planet rather than an actual planet.

This is rather a difficult thing to do. You can not be a member without being a member.

Neptune. (Pluto is no longer considered a planet, but, rather, a dwarf planet.)
Pluto is now classified as a dwarf planet rather than an actual planet.
Kepler discovered that the orbit of each planet is an ellipse rather than a perfect circle. The planet with an orbit that is closest to a circle is Venus.
When a planet moves around a star, it causes the star to wobble a bit from side to side as planets follow an elliptical orbit rather than a circular orbit. Astronomers can then use this fact to see whether stars have planets.
The planet Uranus is hotter at its poles than at its equator because the planet is tilted on its side. Astronomers believe that an Earth sized object collided with the planet millions of years ago and tilted it so that its poles faced the sun rather than its equator.
No. Mercury orbits the sun, so it is a planet rather than a moon.
I've never heard anybody use the phrase "on the sky" in any context.
