The angular velocity of Earth is 15 degrees an hour, 360 degrees over a 24 hour period.
Both the earth and the moon actually revolve around each other as they revolve around a gravity centered point. This point is much closer to the earth because the earth has much more mass. They are so close together that NASA has than decided that it looks like the moon and earth have been dancing for years!
365.24 days, exactly the same length of time as the earth takes. If the moon took more or less time than the earth does to revolve around the sun, even by a very small amount, then over a period of many years, the moon would either pull way ahead of the earth, or else fall far behind. That doesn't happen, because earth and moon revolve around the sun together, in the same time.
Mars. The further out from the sun, the longer a planet takes to revolve round the sun. For example, Pluto's orbit takes over 200 (Earth) years.
The earth does not rotate around the moon. The moon rotates around the earth. Neither one constitutes a day. A day is the time for the earth to revolve once in relation to the sun. It is the time from when the sun is directly over head until the time the sun is directly over head again.
If you were hanging up in space, far over the Earth's north pole and looking downat the whole system, you would report that the Earth is revolving around the suncounterclockwise.But . . .If you were hanging up in space, far over the Earth's south pole and looking downat the whole system, you would report that the Earth is revolving around the sunclockwise.
It takes the moon a little over 27 days to orbit around the Earth. The moon also rotates at exactly the same rate it revolves, so we always see the same side of the moon.
There's climate all over the Earth.
Too much or more than needed.
Earth's rate of revolution about the sun has changed very little over the past few million years. It is not likely to have changed significantly in several billion years. There is, however, evidence some of the planets have migrated inward and outward a bit since the time of their formation 4.5 billion years ago.
the amount of bacteria on Earth would have to be at least over 100.
