Reading Kepler-1692 b’s atmosphere

Dominant elements: O, Si, Fe, N, H, CThis is what a telescope would measure while Kepler-1692 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-1692 b sits about 1928 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.

Rocky TerrestrialUninhabitable1927 light years awayFound 2020

Kepler-1692 b, from the NASA Exoplanet Archive (found 2020). Measured: 1.42 Earth masses, 0.0646 AU, a 5146 K K-type star. Composition inferred from a measured bulk density of 1.04x Earth's, which is rock and iron, with a day locked to its 6.0-day year, as anything orbiting this close would be.

Rocky Terrestrial

No life — too hot for liquid waterModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (24.6%) 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: 24.6% + Iron: 12.3% + Magnesium: 3.6%✓ Mass: 1.4x Earth (terrestrial range)

A binary star system's orrery: two suns close together, a red dashed dead-zone boundary, and a debris trail left by a destroyed world

New: Binary Star Systems 🌀

A system can now orbit two suns. Add a companion star when you build one — close, medium, or wide — and the physics decides what survives: a shared center of mass carves out a dead zone where gravity from both stars tears a world apart, leaving it as debris, and every surviving planet's orbit goes elliptical, moving fastest at closest approach and slowest out at aphelion. Push the separation to wide and the dead zone opens tens of AU across, wide enough to gut a system that would have been stable around one star alone. Stand on a world that made it through and you'll watch two suns cross the sky together.
