TOI-700 e

TOI-700 e is a confirmed rocky exoplanet 102 ly from Earth in the constellation Dorado, discovered in 2023 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.

Standing on TOI-700 e, you would weigh roughly about 10% less than you do on Earth. Its red dwarf looks 3.1× wider than ours, bathing the surface in deep 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 28 days, and at an estimated 0°C (32°F) it is cold.

EARTH HEIGHT≈ 1.0xEARTH-RAISEDRAISED HERE
much like Earth height

Gravity close to Earth's, at about 0.90 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 0°C (32°F), sound would travel close to its Earth speed, so your voice would sound much as it does on Earth. The real atmosphere is unknown.

The journey
Cosmic travel advisory
★★★★★
Highly recommended
  • Surface temperatures near 0°C (32°F) fall in the range where liquid water is at least possible.
  • Surface gravity is close to Earth's, about 0.90 times, so you would move much as you do here.
  • A high Earth-similarity index of 0.94, among the more Earth-like worlds known.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

Common questions

What is the gravity on TOI-700 e?

TOI-700 e's surface gravity is about 0.90 times Earth's, estimated from its size.

How much would you weigh on TOI-700 e?

Someone who weighs 150 pounds on Earth would weigh about 135 pounds on TOI-700 e.

How far is TOI-700 e from Earth?

TOI-700 e lies about 102 light-years from Earth.

How long would it take to get to TOI-700 e?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 158,333 years.

How hot is TOI-700 e?

TOI-700 e's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 0°C (32°F).

Is TOI-700 e habitable?

TOI-700 e orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.94. 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-700 e?

TOI-700 e completes one orbit of its star in 28 days.
