Habitable zone

Star and planets drawn to scale: the star is 58 times as wide as Kepler-367 b, so only its edge is in view. Orbits spaced as in the star system view.

Kepler-367 b, from the NASA Exoplanet Archive (found 2014). Measured: 2.24 Earth masses, 0.201 AU, a 4710 K K-type star. Composition inferred from a measured bulk density of 1.02x Earth's at this size, suggesting roughly 8% water/ice by mass, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Life unlikely — too hot for liquid waterMagnetic FieldHigh Activity
Kepler-367 b is dominated by silicate (23.2%) and iron (11.6%) 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: 23.2% + Iron: 11.6% + Magnesium: 3.4%✓ Mass: 2.2x Earth (terrestrial range)

Reading Kepler-367 b’s atmosphere

Dominant elements: O, Si, Fe, N, H, CThis is what a telescope would measure while Kepler-367 b 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-367 b sits about 613 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.
