How would the planets move if the Sun disappeared?

Back

The planet would move in a straight line in the direction it had been traveling, because of its inertia.

What are the steps of the Nebular Theory?

Back

Step 1: Gravity pulled together atoms in a nebula. Step 2: Nuclear fusion occurred and a star is born. Step 3: Smaller clumps around the star formed into planets.
