BD-08 2823 b
BD-08 2823 b is a confirmed sub-Neptune exoplanet 135 ly from Earth in the constellation Sextans, discovered in 2009 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its orange dwarf looks 11.8× wider than ours, bathing the surface in amber-orange 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 5.6 days, and at an estimated 526°C (978°F) it is furnace-hot.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 526°C (978°F), sound would travel roughly 67% 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 526°C (978°F), with no liquid water and no shade anywhere.
- !Its star delivers about 66 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
