Kepler-1459 b
Rocky TerrestrialMarginal1483 light years awayFound 2016
Kepler-1459 b, from the NASA Exoplanet Archive (found 2016). Measured: 2.42 Earth masses, 0.283 AU, a 4828 K K-type star. Composition inferred from a measured bulk density of 0.96x Earth's, which is rock and iron, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Rocky Terrestrial
Magnetic FieldHigh Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (25.0%) and iron (12.5%) 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.
Classification Criteria:
✓ Silicon: 25.0% + Iron: 12.5% + Magnesium: 3.8%✓ Mass: 2.4x Earth (terrestrial range)

Contributing Factors
temperature40
Extreme temperature - very difficult for life
atmosphere70
Nitrogen atmosphere provides protection but not breathable
water46
Limited water content - likely as steam
magnetic Field100
Magnetic field provides radiation protection
geology90
Active geology recycles nutrients and drives carbon cycle
Organic Chemistry80
Core organic elements (CHNO) present
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution
