All the planets revolve around the sun. The closest is Mercury, followed by Venus, Earth, Mars, astroid belt, Jupiter, Saturn, Uranus and Neptune. Pluto and an unnamed body are next, but Pluto has been declassified as a planet.

It's hard to give a good example, but it is centripetal force that keeps the Earth revolving around the sun. When an object such as a satellite revolves around the Earth, or a planet around the sun, there are two different forces at work. One is gravity, which tries to pull the object inward; the other is centripetal force which tries to force the object outward, The best example i can give is a rock tied to the end of a string. When the string is whirled around, the rock tries to fly away but the string holds it back. The result is that angular momentum keeps the rock moving in a circle. If the rock were the Earth, and the hand holding the string were the Sun's gravity, you would have the centripetal (outward) force of the moving Earth straining against the gravity of the Sun trying to pull it inward. When the two forces balance, it forms a stable orbit in which gravity and centripetal force are equally and oppositely matched and cancel each other out.

Not really it just appears that way. Actually the Earth and the Sun orbit each other all at the same time.The earth traces a larger orbit the Sun traces a much smaller orbit.
All the planets follow the same scenario all athe same time.
This knowlege is know by few. The Reason is that it cant be belived that the Sun orbits also all the Planets at the same time. In the same instance the whole solar system revolves relative to the Bary center of the Milky way at a velocity of 250 kilometer per seconds.

According to those who write about
the artic from firsthand experience, the Sun “makes distant lazy circles in
the southern sky”. These circles are entirely above the horizon for a season,
and entirely below for another season. To those in the far north or far
south, the Sun does not seem to revolve around the Earth.So the earth instead revolves around the sun. It revolves in a counter clockwise direction, in the speed of 29.8 km/s.

Yes it Revolves around the sun,which makes the different seasons. And it Rotates on its axis, which makes days and nights,

The earth rotates on its own axis and revolves around the sun.

Now you are no longer the last person in the world to know this. I guess AL R is the last one.

yes. but is the sun circuling the galaxy? Can someone ask NASA to make sure of this, please? Coz the galaxy could be circuling our sun for all we know. There something i believe, that as above, so below. What we know of above us is almost to me as superstition. Maybe everyone should give up thier knowledge and we can all stop thinking. And maybe, just maybe we can be more understanding more than we are
intelligent. then maybe our conciousness can grasp the one true and this earth becomes heaven. Can you imagine if everyone is as loving? Gosh, it'll be hillarious!

yes it does. gallileo helped prove this theory. it is called the heliocentric theory, meaning the sun is the center of the universe, which its not because we have no way of measuring the universe (the closest thing we have is stellar paralax) but that's just for two objects. but the sun is the center of our solar system

The Earth revolves around it´s own axis and circles the sun.
My mistake . I should have said , orbits the sun. As the Earths orbit is not circular then it is not correct to use the terminology, revolve.
