If M is the Moon's sidereal orbital period (in days), then the Moon revolves around the Earth at a rate of 360 / M Â° per day. So in a time interval t days, the Moon revolves around the Earth t Ã 360 / M Â°. If Y is the Earth's sidereal orbital period in days, then the Earth revolves around the Sun at a rate of 360 / Y Â° per day and so in t days the Earth revolves around the Sun t Ã 360 / Y Â°.
