HD 176986 c
HD 176986 c is a confirmed sub-Neptune exoplanet 90.6 ly from Earth in the constellation Aquila, discovered in 2017 by Multiple Observatories.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its orange dwarf looks 6.6× 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 17 days, and at an estimated 285°C (545°F) it is blistering.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 285°C (545°F), sound would travel roughly 39% 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.
