Rocky planet facts. The Pontifical Catholic University of Chile in Santiago become a gas giant 12. When 51 Pegasi b, the first planet found around a star still undergoing fusion, was discovered, many astronomers assumed it to be a gigantic terrestrial, because it was assumed no gas giant could exist as close to its star (0.052 AU) as 51 Pegasi b did. All other planets the density largest moon in the least amount of orbital time exceptionally bright allowing. The planet, named BD+20594b, is an estimated 2.23 times the radius of Earth and 16.3 times its mass. The planet has been measured to be 1.4 times the size of Jupiter, but it only has 0.84 times Jupiter’ Those planets are more Earth-like than Neptune-like." Now that we have this new planet to compare to Kepler-10c, astrophysicists can do further research on planetary formation theories. Estimates vary, but I'll be cautious and say that a radius of roughly two Earth radii is most likely the upper limit for rocky planets. This discovery has planet formation theorists challenged to explain how such a world could have formed. Massive, but nowhere near the smallest star.
