Rocky world

TOI-431 c

TOI-431 c is a confirmed rocky exoplanet 106 ly from Earth in the constellation Lepus, discovered in 2021 by La Silla Observatory.

Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.

Standing on TOI-431 c, you would weigh roughly about 27% more than you do on Earth. Its orange dwarf looks 14.0× 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 4.8 days, and at an estimated 594°C (1101°F) it is furnace-hot.

Gravity close to Earth's, at about 1.3 times. A child would grow up much as they would back home.

A playful thought experiment from this world’s gravity, not a prediction about any real person. No human has ever grown up off Earth, so no one truly knows; the direction (taller in low gravity, shorter and stockier in high) follows how growing bodies respond to weight.

Your voice would sound high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 594°C (1101°F), sound would travel roughly 74% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !Furnace-hot at around 594°C (1101°F), with no liquid water and no shade anywhere.
  • Surface gravity is close to Earth's, at least 1.27 times, so you would move much as you do here.
  • !Its star delivers about 101 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

Common questions

What is the gravity on TOI-431 c?

TOI-431 c's surface gravity is at least 1.3 times Earth's, and possibly more: its mass is only a lower bound.

How much would you weigh on TOI-431 c?

Someone who weighs 150 pounds on Earth would weigh at least 191 pounds on TOI-431 c.

How far is TOI-431 c from Earth?

TOI-431 c lies about 106 light-years from Earth.

How long would it take to get to TOI-431 c?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 165,669 years.

How hot is TOI-431 c?

TOI-431 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 594°C (1101°F).

How long is a year on TOI-431 c?

TOI-431 c completes one orbit of its star in 4.8 days.
