Destroyed — no longer habitable Low Activity
Why is this a Rocky Terrestrial? Your planet is dominated by silicate (16.9%) and iron (10.1%) content, forming a rocky terrestrial body. Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
