What separates the terrestrial planets from the Jovian or gas planets in space? The third hypothesis maintains that hot Jupiters get close to their star later, when the gravity of other planets around the star can drive the migration. One idea posits that hot Jupiters begin their journey early in the planetary system's history while the star is still surrounded by the disk of gas and dust from which both it and the planet formed. A study refutes the theory that phosphine gas, which can indicate microbial life, was found in the clouds above Venus. WebWhat are Gas Giants?

The Planets: The Definitive Visual Guide to Our Solar System (opens in new tab) by DK, is also an excellent illustrative guide to all things planets. The formation of a gas giant A planet acquires an atmosphere if gas is available and if the planet's gravity is strong enough to stop the atmosphere escaping. The reason this is a "forbidden" planet is that current observations and the core accretion model would expect that there should not be enough mass in the proto-planetary disk of an M-dwarf star to form a planet this large.
