Not the size of the mass, It's the Miles in the orbit!
Neptune needs 165 years to orbit the sun once.
It has been orbiting the sun since it was formed.
The Moon has no rings. The only planets that have rings are Jupiter, Saturn, Uranus, and Neptune.
The Moon orbits the Earth, the Earth orbits the Sun
No!The Sun orbits around the galactic center, one revolution in about 220 000 000 years.
yes it dose it rotates backwards
Neptune is a gaseus planet. it has no physical surface that you could walk on, but a gas surface.
What is "it"? The moon?
It takes the moon approximately 27.3 days to orbit around the Earth and complete one full cycle. This period is known as the sidereal month.
All the planets orbiting the sun can be called moons of the sun
Neptune has 13 moons. The largest moon is Triton. :)
