it never stops spining.
One complete rotation of the earth on its axis is called ONE DAY
It takes 1 sidereal day for the to earth to spin on its axis. That is 23.93447 hours.
1
27.32 earth days
No. Each of those "days" of which the question speaks is the length of time it takes for the earth to spin on its axis. The question is actually referring to the moon, which takes 27.32 days to spin once on its axis.
For one axial rotation it takes 243 Earth days.
A Mercurian "day" the (time it takes it go spin once on it's axis) is equal to 58.65 earth days. Mercury turns on it's axis very, very slowly.
They spin at a different rate on their axis than the Earth does on its axis.
10 hours. Or two and a fraction per Earth day.
"revolution" , if you mean to do a revolution around the sun then 365.25 days which is 1 year. if you mean to spin on its own axis then its 1 day then day is measured in how long it takes the earth to spin around its own axis
Venus rotates once in 243 days.
365 days in a year 366 days in a leap year.
27.32 days
