2.

Kepler's 2nd Law states that

All planets travel in an elliptical orbit

Planets will sweep out equal areas of their orbits in equal time

The square of a planet's period will be equal to the distance of that planet from the Sun cubed.

The force of gravity increases with the masses of the objects in a system and decreases as those objects get closer to one another.

3.

A tiny solar system is discovered in a far corner of our Galaxy. In that solar system the mass of the star is 300,000,000 kg and the mass of it's closest orbiting planet is 47,500 kg. If that planet is 23,400,000 meters away from the star, what is the force of gravity between that star and it's planet?
