Why is this a Rocky Terrestrial? Your planet is dominated by silicate (3.8%) and iron (5.8%) 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: 3.8% + Iron: 5.8% + Magnesium: 6.7% ✓ Mass: 2.9x Earth (terrestrial range)
Reading your planet’s atmosphere Dominant elements: H, O, C, Mg, N, Al This is what a telescope would measure while your planet crosses in front of its star: starlight passes through the atmosphere and spreads into a rainbow band. Each dark line marks a wavelength the atmosphere absorbed. Every element absorbs its own signature wavelengths — hydrogen always darkens the same two spots, calcium another pair, and so on. Astronomers match the lines in a real spectrum against a library of these signatures to say what an atmosphere is made of, light-years away, without ever visiting. A deeper line generally means more of that element is present. For a real planet, distance is usually measured by parallax: as Earth orbits the Sun, a nearby star appears to shift very slightly against the distant background stars, and the size of that shift gives its distance directly — the same geometry surveyors use, at an interstellar scale.

Habitability ✓ Conditions could support life This planet’s modelled conditions could support biological processes: stable temperatures, liquid water and the chemistry life as we know it needs. That makes life possible, not present.
