Mercury is a rocky planet has no atmosphere. It is the planet closest to sun and the smallest. Its diameter is 4,879 km, a similar size diameter of the moon. It may be that long ago would have been a natural satellite of Venus.
If Mercury before had been a satellite of Venus¿as it has become a planet? My theories:
1:can be super gravity of the sun was attracting mercury slowly and then attract both Mercury became a planet.
2: Another theory could be that an asteroid the size of Mars slammed into Mercury pushed him and the sun’s gravity pulled him and became a planet.
