What is Keppler's second law
Planet's orbital speed changes depending on the distance they are from the sun. the closer they are the faster they go, the farther away they are the slower their speed is.

What is Cosmic Background Radiation?
Electromagnetic radiation that's leftover from the first moments of the big bang.
Why are outer planets gas giants?
During the process of being formed, the gas giants were away from the sun and as a result, they could not meld with heavy elements because the sun would melt it and let the planet meld with it, and so they meld with gasses and as a result, they grew bigger since the heaver elements kept the planets small.
