Why all planets moves around sun?

Most people take this fact for granted, but the answer involves many interesting ideas and important concepts. I'll touch on a few. First of all, saying the planets go around the Sun is just another way of saying the planets are in orbit around the Sun. A planet orbiting the Sun is like the moon or a NASA satellite orbiting Earth. read more

The Sun, the Moon, the planets and the stars appeared to move around the Earth each day. And because the Earth itself didn’t seem to be moving, astronomers like Ptolemy assumed that Earth was the center of the Universe. read more

For example, the Earth completes one rotation about its axis about every 24 hours, but it completes one revolution around the Sun about every 365 days. Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. read more

Sun’s diameter is 11 times larger than Jupiter and you can fit 1,300,000 Earths inside Sun and the gravity depends on the mass of the body and Sun has a very huge mass with a very strong gravity and as the Sun rotates the planets who also have mass and gravity revolve due to the gravitational pull of the Sun that is the reason all planets moves around sun. read more

Well, in addition to falling toward the Sun, the planets are moving sideways. This is the same as if you have a weight on the end of a string. If you swing it around, you are constantly pulling it toward your hand, just as the gravity of the Sun pulls the planet in, but the motion sideways keeps the ball swinging around. read more
