Planets & Celestial Bodies

Nebular Theory says the solar system started as a big cloud of rotating gas.

The sun is a minimal component of the solar system in terms of mass.

Jovian planets hold more gases due to having a larger mass that contains gas and being farther away from the sun being exposed to less solar heating.

Solar heating of gases allow them to remain in the atmosphere.

The four terrestrial planets are known as the outer planets.

The outer planets are known as the Jovian planets.

Every Jovian planet does not have rings.

A crater is a small planetary impact from a celestial body.

The moon has an atmosphere so it does not have craters.

Maria are the dark lowlands on the moon that resemble seas and basalt plains named by Galileo.
