Second Sister (Kilian II)

The Second Sister (Kilian II) is a protoplanet in the [Kilian system](https://robertsspaceindustries.com/galactapedia/article/0ODD4mY9aP-kilian-system), [United Empire of Earth (UEE)](https://robertsspaceindustries.com/galactapedia/article/VyvyKxy4v6-united-empire-of-earth). Misshapen and low in mass, it is theorized that the Second Sister was trapped in the orbit of the [First Sister (Kilian I)](https://robertsspaceindustries.com/galactapedia/article/VlMMagKEzd-first-sister-kilian-i) as it was passing through the system. The [UEE Navy](https://robertsspaceindustries.com/galactapedia/article/RPDvKOpdP4-uee-navy) uses the Second Sister as a testing ground for weapons. Due to this, access to the Second Sister is restricted.
