Question

Which celestial body shares its orbit with others? Give an example.

Answer 1

While the whole thing is still under study, it has been observed that two celestial bodies actually share their orbits while going around a star.

If this theory is confirmed, then claims will be made that the earth once shared orbit with another celestial body, which faced a collision and went away to form the moon.

Answer 2

Neptune's orbits and Pluto orbit are not on the identical plane. In 1999, it slid beyond Neptune and became the ninth planet. But  However, for 20 years out of every 248 years Pluto's orbit "intersects" inside of Neptune's orbit. Pluto last intersected inside Neptune's orbit on February 7, 1979, and provisionally converted to become the 8th planet from the Sun from the position of the 9th planet.

So many of the big celestial body who shares its orbit with others are now considered as a “dwarf planet,” and which now includes Pluto, which is no more the planet in the solar system and shares its orbit with Kuiper belt such as the plutinos.
