The time it takes Earth to orbit around the sun is a year


Why is the sun moving in the sky when the earth is rotating around the sun?

The Earth itself is rotating @ 1 revolution per day -hence the 'Sun moving in the Sky': meanwhile the Earth is following an elliptical track around the Sun whilst itself spinning.


How does the. Earth and moon move around the sun?

The earth is moving for both of tham.


The Earth orbits around the sun because the gravitational force that the sun exerts on the Earth?

Yes, the Earth orbits around the sun due to the gravitational force exerted by the sun. This force keeps the Earth moving in a curved path around the sun, preventing it from simply moving in a straight line out into space.

Is earth still or moving?

How can the moon and sun tell us that the earth is moving?

The moon and sun can tell us that the earth is moving as our earth spins adding to the sight of turn of the Moon which we can see in the sky moving throughout the day. The sun can tell us the earth is moving as we can see shadows on people and objects moving around telling us something has to be moving. It has been scientificly proven that is not the Sun or "Sol" so we know it is the Earth.


What would happen to the season if the earth did not revolve around the sun?

If the earth did not revolve around the sun, there would not be any seasons. The problem is that if the earth did not revolve around the sun, that is, if it came to a stop in its orbit, the sun's gravity (with just the tiniest help from the earth's) would pull the earth into the sun.


Why might ancient astronomers have been convinced that the sun and moon revolve around earth?

Because in the sky it looks as if the sun is moving, but actually, the earth is moving but you can't feel it.


What is the path taken by the earth to complete one revolution?

There is no specific path in space.The earth moves around the sun relative to the sun.But the sun itself is moving and therefore the Earth's orbit is also moving.


Why is the earth falling and also going around the sun?

It is falling through space even though moving around the sun. The inertia of the "fall" and the pull of the gravity of the sun, make the earth go around the sun in an ecliptic orbit.


How much mile per hour does the sun go around the Earth?

It's the other way around; the Earth goes around the Sun. The Earth is in an elliptical orbit (but not very elliptical; only about 3% difference from a perfect circle) so the speed of the Earth's movement around the Sun varies a bit. It's moving fastest around January 4, when the Earth is closest to the Sun (called "perihelion"), and moving slowest in early July, when the Earth is farthest away (which we call "aphelion"). But on average, it's moving about 67,000 miles per hour in its orbit.
