Kepler-52 c
Kepler-52 c is a confirmed sub-Neptune exoplanet 1,049 ly from Earth in the constellation Draco, discovered in 2012 by Kepler.
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 orange dwarf looks 5.0× 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 16 days, and at an estimated 160°C (320°F) it is blistering.
Catalog values (NASA Exoplanet Archive): mass 45.40 M⊕, radius 1.84 R⊕. Its catalog mass and radius imply a density of 40.2 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use Kepler-52 c in gravity rankings or weight calculations.

Your voice would sound noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 160°C (320°F), sound would travel roughly 23% faster than on Earth, so your voice would sound noticeably higher and reedier. The real atmosphere is unknown, so this is a best guess.

- !Persistently hot at around 160°C (320°F), well above anything you would call comfortable.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

How far is Kepler-52 c from Earth?
Kepler-52 c lies about 1,049 light-years from Earth.
How long would it take to get to Kepler-52 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 1.6 million years.
How hot is Kepler-52 c?
Kepler-52 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 160°C (320°F).
How long is a year on Kepler-52 c?
Kepler-52 c completes one orbit of its star in 16 days.
