Compounded research on space rock collisions has revealed much information in the mechanics of our solar system. Scientists believe that they may have discovered the first instance of rock collisions under an exoplanetary setting.
The finding arose through the observation of exoplanet, Kepler 107, a star-like entity with 4 orbiting planets. Through the study of two of its innermost planets, experts theorize the possibility of rock collisions that may have led to the disparity in mass between the planets in question.
However, scientists continue to investigate the verity of the inference since the structure of both planets have been extrapolated based on density values and may prove inaccurate.
