KOI-2513.01
KOI-2513.01 is a confirmed sub-Neptune exoplanet 4,468 ly from Earth in the constellation Cygnus, discovered in 2023 by Kepler.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it (what that means).
Its yellow, Sun-like star looks 2.4× wider than ours, bathing the surface in warm white light. A year passes in just 19 days, and at an estimated 485°C (905°F) it is furnace-hot.
Catalog values (NASA Exoplanet Archive): mass 7,310 M⊕, radius 2.80 R⊕. Its catalog mass and radius imply a density of 1830.4 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use KOI-2513.01 in gravity rankings or weight calculations.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 485°C (905°F), sound would travel roughly 62% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

- !Furnace-hot at around 485°C (905°F), with no liquid water and no shade anywhere.
- !Its star delivers about 78 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Earth-similarity index 0.05: this world has almost nothing in common with our own.
