MWC 758 c
MWC 758 c is a confirmed sub-Neptune exoplanet 520 ly from Earth in the constellation Taurus, discovered in 2023 by Large Binocular Telescope Observatory.
Imaging: photographed directly, as a faint point of light beside its star.
Its yellow-white star looks 0.02× as wide as ours, bathing the surface in bright white light. At an estimated 227°C (440°F) it is blistering.

Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 227°C (440°F), sound would travel roughly 32% 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.

How far is MWC 758 c from Earth?
MWC 758 c lies about 520 light-years from Earth.
How long would it take to get to MWC 758 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 811,526 years.
How hot is MWC 758 c?
MWC 758 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 227°C (440°F).
