Why is this a Rocky Terrestrial?Your planet is dominated by silicate (19.4%) and iron (20.4%) 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: 19.4% + Iron: 20.4% + Magnesium: 8.2%✓ Mass: 0.6x Earth (terrestrial range)
