Why is this a Rocky Terrestrial?Your planet is dominated by silicate (15.2%) and iron (15.2%) 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: 15.2% + Iron: 15.2% + Magnesium: 0.0%✓ Mass: 0.5x Earth (terrestrial range)
