Its orange dwarf looks 16.0× 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 3.9 days, and at an estimated 562°C (1043°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 562°C (1043°F), sound would travel roughly 70% 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.

Cosmic travel advisory
☆☆☆☆
Do not travel
  • !Furnace-hot at around 562°C (1043°F), with no liquid water and no shade anywhere.
  • !Its star delivers about 52 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
