attraction...mass
attraction...orbits
repulsion...mass
repulsion...orbits

Explanation:

1. The text states gravity is a force of attraction between all matter, so the first blank is "attraction".
2. The text notes gravity causes celestial objects to orbit each other and drives the formation of celestial bodies; the context of the sentence links gravity to the orbital motion of moons, planets, stars, so the second blank is "orbits".

Answer:

attraction...orbits
