Rocky world

TOI-6008 b

TOI-6008 b is a confirmed rocky exoplanet 75.3 ly from Earth in the constellation Cygnus, discovered in 2024 by Transiting Exoplanet Survey Satellite (TESS).

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 red dwarf looks 22.4× wider than ours, bathing the surface in dim red light. It is likely tidally locked, so that sun never moves in the sky: one hemisphere in endless day, the other in permanent night. A year passes in just 20.6 hours, and at an estimated 434°C (813°F) it is furnace-hot.

Catalog values (NASA Exoplanet Archive): mass 4.00 M⊕, radius 1.03 R⊕. Its catalog mass and radius imply a density of 20.2 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use TOI-6008 b 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 434°C (813°F), sound would travel roughly 57% 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.
