    If Mercury or a rogue planet of similar size were to collide with Earth, all life on Earth could be obliterated entirely: an asteroid 15 km wide is believed to have caused the extinction of the non-avian dinosaurs, whereas Mercury is 4,879 km in diameter. [135] The destabilization of Mercury's orbit is unlikely in the foreseeable future. [136]
