WASP-53 c
WASP-53 c is a confirmed sub-Neptune exoplanet 657 ly from Earth in the constellation Cetus, discovered in 2017 by Multiple Facilities.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its orange dwarf looks 0.21× as wide as ours, bathing the surface in amber-orange light. A year here lasts 7.8 Earth years, and at an estimated -163°C (-261°F) it is colder than almost anywhere in the solar system.

Your voice would sound deep and slow, dropped to a low bass.
Assuming Earth-like air at this world's temperature of about -163°C (-261°F), sound would travel roughly 38% slower than on Earth, so your voice would sound deep and slow, dropped to a low bass. The real atmosphere is unknown, so this is a best guess.

How far is WASP-53 c from Earth?
WASP-53 c lies about 657 light-years from Earth.
How long would it take to get to WASP-53 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 1.0 million years.
How hot is WASP-53 c?
WASP-53 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -163°C (-261°F).
How long is a year on WASP-53 c?
WASP-53 c completes one orbit of its star in 7.8 years.
