They don't - new born stars and planets are formed together.
Both new planets and stars are being formed. Scientists are actually watching the formation of planets and keeping track of which ones would be able to support life.
The other planets, stars, galaxies, meteors, comets, and asteroids.
No - without gravity, galaxies would not have formed, planets would not have formed, stars would not have formed.
Everything happened after the big bang.

Planets are formed when the surface phase changes to a solid material. All planets were once stars.
Planets (and stars) were formed out of dust and gas. That had a rotation to it which does not go away (this is known as the Conservation of Angular Momentum).
Planets are not formed by exploding stars!Planets are formed of the material left behind as a star forms from the dust and gasses of a collapsing molecular cloud.A distant exploding star may provide the initial compression wave that triggers the collapse of the molecular cloud leading to the formation of new stars and the planets around them. But there are other mechanisms having nothing to do with stars that might trigger this also.
Planets orbit stars.
No. Planets are formed after stars are and in most cases planets are consumed by the same star. Some stars can exist long after they have exhausted their supply of hydrogen and heavier element as red giants. Some even may last over 100 of trillions of years.
