gravity
When a star explodes, it is referred to as a nova. If the star is large enough, it will create a super nova. And if the star is dense enough, it does not explode, but instead collapses on itself and forms a black hole
what is the terrestrial planet that has no atmosphere
elliptical galaxy....
Neptune
As water is cooled its density increases until it reaches about 4 C and then it decreases.
An creation disk may eventually form a
Gas giants have a higher mass.
This means that the gas giants have a more gravity to hold moons in orbit around them.
Terrestrial means on Earth so Earth is the only terrestrial planet
This is incorrect, the first 4 planets are terrestrial as they are solidly bound planets. Pluto was also a terrestrial dwarf planet. Any planet can have moons but due to the gas giants having larger gravitational forces they have traditionally gathered more moons. Thusly, no.

Titan is a moon the orbits around Saturn. This is a planet.
