HD 7199 b
HD 7199 b is a confirmed sub-Neptune exoplanet 118 ly from Earth in the constellation Tucana, discovered in 2011 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Its yellow, Sun-like star looks 0.71× as wide as ours, bathing the surface in warm white light. A year here lasts 1.7 Earth years, and at an estimated -54°C (-66°F) it is deeply frozen.
What these mean: surface gravity · tidal locking · equilibrium temperature · habitable zone

Your voice would sound deeper and fuller.
Assuming Earth-like air at this world's temperature of about -54°C (-66°F), sound would travel roughly 13% slower than on Earth, so your voice would sound deeper and fuller. The real atmosphere is unknown, so this is a best guess.

- !Cold at about -54°C (-66°F), survivable only fully suited and heated.
- It orbits within the habitable zone, where a world could in principle hold liquid water.

How far is HD 7199 b from Earth?
HD 7199 b lies about 118 light-years from Earth.
How long would it take to get to HD 7199 b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 183,902 years.
How hot is HD 7199 b?
HD 7199 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -54°C (-66°F).
Is HD 7199 b habitable?
HD 7199 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 7199 b?
HD 7199 b completes one orbit of its star in 1.7 years.
