The HIP68468 star has the same size, mass, and brightness as the Sun and has many signs that it has swallowed some planets in the system.

HIP68468 contains 4 times the amount of lithium (lithium) normal in stars of the same age. This proves that it has swallowed up some planets in the past. The star also carries more metal than other rock planets.
