"Jovian" planets are considered to be mainly made up of various gases, and are also known as "gas giants".

Jupiter, Saturn, Neptune, and Uranus (Haha, very funny) are all considered Jovian planets."Terrestrial" planets are thought of as rocky. A human being could maybe walk on its surface, in a goodspace suit.Terrestrial planets are planets like Earth.
