Habitable zone

Star and planets drawn to scale: the star is 28 times as wide as Kepler-232 c, so only its edge is in view. Orbits spaced as in the star system view.

Kepler-232 c, from the NASA Exoplanet Archive (found 2014). Measured: 14 Earth masses, 0.101 AU, a 5847 K G-type star. Composition inferred from a measured bulk density of 0.25x Earth's, larger than even a pure water/ice world of this mass, suggesting a water-rich interior under roughly a 12% hydrogen/helium envelope by mass, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Surface. No solid surface - a deep volatile envelope over a supercritical water mantle and hot-ice interior

Ice Giant
Magnetic FieldExtreme Activity
Kepler-232 c has moderate mass (14.0x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants.
Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.
Classification Criteria:
✓ Mass: 14.0x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition

Reading Kepler-232 c’s atmosphere

Dominant elements: H, O, Si, Fe, He, NThis is what a telescope would measure while Kepler-232 c 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.Kepler-232 c sits about 4403 light-years away, found by the transit method. Most catalogued distances trace back to 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.

New: Stand on Your Moons 🌒

A planet's surface view isn't the only ground any more. Press the surface button on a planet with moons and it asks where to stand: the planet itself, or any moon still in orbit, each tagged with what it became — ocean, ice, carbon, volcanic. Every moon gets its own ground and sky from its own physics: airless rock under a black sky, ice cracked by geysers over a hidden sea, sulfur plains shaking with eruptions, or orange haze you can't see the sun through. And hanging over the horizon, there's the planet you built.
