Scientists have found that most known exoplanets share many similarities with the jovian planets in our solar system, such as size, density, and composition. Exoplanets are probably made of hydrogen and helium gas. Since these planets orbit close to their stars, their temperatures are probably much higher than temperatures on the jovian planets Another 1340 (31%) have been terrestrial planets that are several times more massive than Earth (Super-Earths) while 163 have been comparable to Earth in terms of size and mass (4%) Thousands of exoplanets have been discovered so far, of many different types, but they all share one thing in common: they have all been found in our own galaxy.
