WASP-47 c
WASP-47 c is a confirmed sub-Neptune exoplanet 864 ly from Earth in the constellation Aquarius, discovered in 2015 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its yellow, Sun-like star looks 0.83× as wide as ours, bathing the surface in warm white light. A year here lasts 590 days, and at an estimated -26°C (-15°F) it is cold.
What these mean: surface gravity · tidal locking · equilibrium temperature · habitable zone

Your voice would sound much as it does on Earth.
Assuming Earth-like air at this world's temperature of about -26°C (-15°F), sound would travel roughly 7% slower than on Earth, so your voice would sound much as it does on Earth. The real atmosphere is unknown, so this is a best guess.

- Surface temperatures near -26°C (-15°F) fall in the range where liquid water is at least possible.
- It orbits within the habitable zone, where a world could in principle hold liquid water.

How far is WASP-47 c from Earth?
WASP-47 c lies about 864 light-years from Earth.
How long would it take to get to WASP-47 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 1.3 million years.
How hot is WASP-47 c?
WASP-47 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -26°C (-15°F).
Is WASP-47 c habitable?
WASP-47 c orbits inside its star's habitable zone, the range of distances where liquid water could be stable. That makes it worth studying, but it is not evidence of life: we have no measurement of its atmosphere, water, or surface.
How long is a year on WASP-47 c?
WASP-47 c completes one orbit of its star in 590 days.
