Why is this a Rocky Terrestrial?Your planet is dominated by silicate (22.5%) and iron (13.5%) 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: 22.5% + Iron: 13.5% + Magnesium: 9.0%✓ Mass: 0.4x Earth (terrestrial range)
