Exoplanet GJ 3512 b, 30 LY From Earth, Seem To Negate Existing Theories On Planet Formation, Which Says Planets Form From Leftover Gas And Dust That Formed A Star (Sun). If That Be The Case, Then Why Would GJ 3512 b, With A Mass 1/2 Of Jupiter, Even Exist, Revolving, In 7 Months, Around A Darwf Sun That’s 12% Mass Of Our Sun?

Astronomers have unexpectedly discovered a gas giant Jupiter-esque exoplanet that’s orbiting a dwarf star, located about 30 light-years from our sun.

The planet, known as GJ 3512 b, completes one orbit around the star every seven months. That makes this a giant planet with a long-distance orbit around a very small star — something that shouldn’t even exist given the current theories about planet formation, according to a new study.
