TOI-712 d

TOI-712 d is a confirmed sub-Neptune exoplanet 191 ly from Earth in the constellation Dorado, discovered in 2022 by Transiting Exoplanet Survey Satellite (TESS).

Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.

much like Earth height

Gravity close to Earth's, at about 1.1 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.

Hear how a voice sounds herea computed acoustic demo

Your voice would sound much as it does on Earth.

Assuming Earth-like air at this world's temperature of about 40°C (105°F), sound would travel roughly 4% faster 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.

The journey
Cosmic travel advisory
★★★★
Recommended, with reservations
  • Surface temperatures near 40°C (105°F) fall in the range where liquid water is at least possible.
  • Surface gravity is close to Earth's, about 1.09 times, so you would move much as you do here.

Common questions

What is the gravity on TOI-712 d?

TOI-712 d's surface gravity is about 1.1 times Earth's, estimated from its size.

How much would you weigh on TOI-712 d?

Someone who weighs 150 pounds on Earth would weigh about 164 pounds on TOI-712 d.

How far is TOI-712 d from Earth?

TOI-712 d lies about 191 light-years from Earth.

How long would it take to get to TOI-712 d?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 298,192 years.

How hot is TOI-712 d?

TOI-712 d's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 40°C (105°F).

Is TOI-712 d habitable?

TOI-712 d orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.66. 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 TOI-712 d?

TOI-712 d completes one orbit of its star in 85 days.
