This is a fascinating theory: the solar system used to have a huge planet between the Sun and Mercury. It cleared out debris from the inner solar system, leaving Mercury, Venus, Earth, and Mars stunted and starved for matter. Then orbital migration of Jupiter and Saturn stole its angular momentum and landed it in the Sun.

I haven’t read the original paper (yet) so I don’t know if this is just a speculative theory or if there are orbital simulations that study the feasibility of this idea.

  1. Mercury is thought to have been hit by another planet and it blew off the other layers of rock and left the core that’s why mercury is like a big ball bearing its almost entirely made of iron

  2. Trillest one No, as I said above it’s just an idea that might explain why our inner solar system seems different from the new planet-rich star systems that have been discovered in the last decade
