HD 160691 b
HD 160691 b is a confirmed sub-Neptune exoplanet 50.9 ly from Earth in the constellation Ara, discovered in 2000 by Anglo-Australian Telescope.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its yellow, Sun-like star looks about the same size as ours, bathing the surface in warm white light. A year here lasts 1.8 Earth years, and at an estimated -11°C (12°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 -11°C (12°F), sound would travel roughly 5% 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 -11°C (12°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 HD 160691 b from Earth?
HD 160691 b lies about 50.9 light-years from Earth.
How long would it take to get to HD 160691 b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 79,344 years.
How hot is HD 160691 b?
HD 160691 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -11°C (12°F).
Is HD 160691 b habitable?
HD 160691 b 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 HD 160691 b?
HD 160691 b completes one orbit of its star in 1.8 years.
