Why is this a Rocky Terrestrial?Your planet is dominated by silicate (33.3%) and iron (20.0%) 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.
✓ Silicon: 33.3% + Iron: 20.0% + Magnesium: 13.3%✓ Mass: 0.4x Earth (terrestrial range)
