Habitable zone

Star and planets drawn to scale: the star is 45 times as wide as WASP-132 c, so only its edge is in view. Orbits spaced as in the star system view.

Sub-Neptune, likely · its density could also fit a water world

WASP-132 c, from the NASA Exoplanet Archive (found 2022). Measured: 6.26 Earth masses, 0.0183 AU, a 4686 K K-type star. Composition inferred from a measured bulk density of 1.00x Earth's, too low for bare rock at this size, suggesting a rocky core under roughly a 0.7% hydrogen/helium envelope by mass, with a day locked to its 1.0-day year, as anything orbiting this close would be.

Surface. No solid surface - a hydrogen-helium envelope wrapped around a rocky core (a sub-Neptune)

Sub-Neptune
Life unlikely — too hot for liquid waterMagnetic FieldLow Activity
WASP-132 c is a sub-Neptune: a 6.3x Earth core wrapped in a deep hydrogen-helium envelope, with no solid surface to stand on.
Sub-Neptunes are the most common planets Kepler found, though our own solar system has none. Too light to be a giant, they still hold on to a thick envelope of light gas over a rocky or icy core.
Classification Criteria:
✓ Mass: 6.3x Earth (under 20x, below the giants)✓ A hydrogen-helium envelope over the core

Reading WASP-132 c’s atmosphere

Dominant elements: O, Si, Fe, N, C, HThis is what a telescope would measure while WASP-132 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.WASP-132 c sits about 401 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.
