Question

why 8 planets are revolving around sun

Answer 1

planets of the Solar System orbiting the Sun. As we move out from Mercury, Venus, Earth and Mars, towards the gas giant planets of the outer Solar System, each of the planets take longer to orbit the sun. ... The planet with the fastest rotation in Jupiter, which rotates every 10 hours.

Answer 2

Hey friend,
Here's ur answer.

Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground. Heavier objects (really, more massive ones) produce a bigger gravitational pull than lighter ones, so as the heavyweight in our solar system, the Sun exerts the strongest gravitational pull.
Forces keeping an object in orbit.
Now if the Sun is pulling the planets, why don't they just fall in and burn up? 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. Without that sideways motion, it would fall to the center; and without the pull toward the center, it would go flying off in a straight line, which is, of course, exactly what happens if you let go of the string.

Hope it helps ...pls mark as brainliest :-) :-)
