The solar system shows quite a big difference between the size of gas filled planet compared to terrestrial planets, but did we find any fully terrestrial planets out there that are as large as gas giants, and how large do they get? In this video the answers to those questions are examined.

Most clips made in this video were made with Space Engine.

0:00 - Difference in density between gas giants and terrestrial planets
0:42 - PSR J1719-1438 b - a white dwarf that turned into a diamond planet
5:50 - Kepler-277b and Kepler-277c
8:01 - How gas giants form and how density of exoplanets is determined
11:04 - LHS 3844 b and TRAPPIST 1b - fully terrestrial planets larger than Earth
16:03 - How giant fully terrestrial planets could form out of stars and gas giants (HD 209458 b)
