The sun used to have rings like Saturn

Before Earth and the other planets in our solar system existed, the sun may have been surrounded by giant rings of dust similar to Saturn’s, according to a new study. 

Those rings of dust may have prevented Earth from growing into a “super-Earth” — a type of planet that is about twice the size of Earth and up to 10 times its mass, according to NASA. Astronomers have discovered super-Earths orbiting about 30% of sun-like stars in our galaxy
