2 times pi times the orbital radius of one AU results in 584,059,067 miles
I think the earth is 93000000 miles from the sun and it spins at about 1000 miles per hour hence it is about 24000 miles around and one revolution is one day
It varies between 27.3 and 29.1 days. with a mean of about 28.5 days. The reasons for these time differences are the Moon's elliptical orbital track about Earth, and thereby the strength of gravitational attraction between the two bodies. Also the gravitational attraction due to the Sun. When at solar perigee gravity is strongest, so nearer and faster, at solar apogee gravity is weaker, so further away and slower.
A revolution is a complete orbit around the Sun. It takes earth about 365.25 days to orbit the Sun.
27.32 days
One year
It takes one year for the earth to revolve around the sun.
One revolution of the Earth is called a day. One orbit around the Sun is called a year.
The earth revolves around the sun every 365 days.
The Moon completes its orbit around the Earth in approximately 27.3 days
The Earth completes one revolution around the Sun in about 365.25 days, which is one year.
88 Earth days to revolve around the Sun.
27.32 days
