Question

why planet rotates about its axis?

Answer 1

because there is gravity in only solar system
so when the planet come on the force uniform linear motion the planet will revolve

Answer 2

Most professionals suppose planets as a rule bought their spin in much the equal way, when clumps of subject collided throughout the planet's formation about 4.5 billion years ago.But why do they spin within the equal direction? When our sun system used to be nothing but a cloud of gasoline and dirt, what was once probably a shock wave from a local supernova bounced up towards it and prompted it to break down. As it collapsed, its own gravitational forces pulled it into a flat, spinning disk. And given that everything in our sun procedure was shaped from that equal disk, its momentum despatched practically the whole thing spinning in the identical course. Our planets have persevered spinning since of inertia. In the vacuum of house, spinning objects preserve their momentum and path their spin considering no outside forces have been utilized to discontinue them. And so, the sector and the relaxation of the planets in our sun system continues spinning.
