Habitable zone

Star and planets drawn to scale: the star is 24 times as wide as TOI-6086 b, so only its edge is in view. Orbits spaced as in the star system view.

TOI-6086 b, from the NASA Exoplanet Archive (found 2024). Measured: 1.76 Earth masses, 0.0154 AU, a 3200 K M-type star. Composition inferred from a measured bulk density of 1.07x Earth's, which is rock and iron, with a day locked to its 1.4-day year, as anything orbiting this close would be.

Surface. Rocky surface with impact craters, possible volcanic features

Rocky Terrestrial
Life unlikely — too hot for liquid waterMagnetic FieldModerate Activity
TOI-6086 b is dominated by silicate (24.5%) and iron (12.3%) 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: 24.5% + Iron: 12.3% + Magnesium: 3.6%✓ Mass: 1.8x Earth (terrestrial range)

Reading TOI-6086 b’s atmosphere

Dominant elements: O, Si, Fe, N, H, CThis is what a telescope would measure while TOI-6086 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.TOI-6086 b sits about 103 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.
