Planets orbit stars, not other planets. A planet-like object that orbits a planet is a moon.
the closer the smaller orbit (a year is one complete orbit) so the year is smaller
No. Venus is the 2nd planet from the Sun; Earth is #3.
Many smaller objects cross Eris' orbit, so it does not dominate its orbital path. An object must clear its orbit of other objects to be considered a planet.
No, a moon cannot be bigger than a planet. Moons are natural satellites that orbit planets, and they are typically much smaller in size compared to the planets they orbit.
A dwarf planet is spherical in shape and orbits the sun without clearing its orbit of smaller debris. Examples of dwarf planets are Pluto and Eris.
The size of a planet's orbit depends on its distance from the star it is orbiting. Planets farther away from the star have larger orbits, while planets closer to the star have smaller orbits. The gravitational pull between the planet and the star also influences the size of the orbit.
Pluto is not a planet because it has not cleared everything from its orbit. The rules of a planet are:It orbits the SunIt is large enough for gravity to squash it into a ballIt must have cleared everything in its orbit (Pluto did not fulfill this).
No. Mars is a planet and thus much smaller than any star. Stars cannot orbit planets. However, Mars does orbit the sun, which is a star.
Comets don't orbit a planet, they orbit the sun.
No, Venus does not orbit a planet. It orbits a star, which is our Sun. It can not orbit a planet , if it did it would be a moon
Through gravitational pull. The largest object will have smaller objects orbit it (objects close in size will orbit each other, but no planet is close to the size of the sun)
