Super-Earths, a common type of exoplanet, do not exist in our solar system, but are found frequently elsewhere in the galaxy. The reason for their absence in our solar system is unclear, with various theories being proposed, including the possibility that similar planets may have existed in the past but were ejected or destroyed. Some research suggests that super-Earths may have formed in our outer solar system, but were later displaced or removed through gravitational forces or other mechanisms.
