Bellerophon is the name given to the first extrasolar planet discovered. It's a hot Jupiter - a gas giant, larger than Jupiter, but very close to its parent star, about 5% the dist that Mercury is from our sun. It's so hot the atmosphere would glow red on the night side and rain would consist of molten iron.
It was discovered using the Doppler method, where the light from the star when analyzed through a spectrometer, reveals that the star wobbles, due to a large mass tugging on it as it orbits the star.
These are a few sequences I animated & rendered for the Nation Geographic show, "Alien Earths"
