HEY ANSWER IS.........!!

1 ↪️ And since everything in our solar system was formed from that same disk, its momentum sent nearly everything spinning in the same direction. (Notable exceptions include Uranus and Venus, whose odd spins probably stem from subsequent collisions with asteroids.) Our planets have continued spinning because of inertia.

2↪️ Planets and stars are round because their gravitational field acts as though it originates from the center of the body and pulls everything toward it. With its large body and internal heating a planet or star behaves like a fluid, and over long periods of time succumbs to the gravitational pull from its center of gravity. The only way to get all the mass as close to planet's center of gravity as possible is to form a sphere. 

3↪️ If space has positive curvature, there is more than enough mass to stop the present expansion of the universe. The universe in this case is not infinite, but it has no end (just as the area on the surface of a sphere is not infinite but there is no point on the sphere that could be called the "end").

I HOPE THIS ANSWER HELPS YOU MORE..........!! ☺️✌️
