Planetary Science

Saturn is the planet with the most visible rings. Saturn's rings are one of the most iconic symbols of astronomy.
Saturn is the planet in our solar system that is famous for the rings.

moderate temperatures and strong gravity (APEX)

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

Orbit

Mercury is the smallest of the terrestrial planets.

elliptical galaxy....

Outward pressure and inward gravity

In a full moon, the Moon is on the other side of Earth from the Sun. In a solar eclipse, the Moon is on the SAME side of the Earth as the Sun.

Cirrus Clouds are mostly made up entirely of ice crystals.

What are the small dense remains of a high mass star

Pluto has five moons.

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.

the giant red spot is found in the planet jupiter.

There is no planet other than Earth that is known to be habitable. By habitable I mean a person could walk on the surface without a space suit and not fry or freeze or suffocate or get a lethal dose of radiation...

Yes, it is a moon of Pluto, which is a Kuiper belt object.

no its caused by the moon moving in to the earths shadow

Mars

When the moon is on the side of the earth opposite the sun you get a full-moon.
