Trivia

What makes it special

Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 1.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 158.5 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1015 years in a starship at a tenth of light speed.
Distance. 102 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1924.

Saying hello

Say hello. A radio message and its reply would take 203 years round-trip.

Standing on it

A year here. A full year lasts just 27.8 Earth days.

By the numbers

Size. Almost exactly Earth-sized.
Mass. About 0.8× the mass of Earth.
Your weight. You'd weigh about 0.9× your Earth weight standing here.
Temperature. A surprisingly temperate -0°C average.

How we found it

Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

Cosmic context

Crowded system. One of at least 4 planets orbiting its star.

About TOI-700 e

TOI-700 e is an epic exoplanet. It lies about 101.5 light-years from Earth, has an equilibrium temperature near 273 K, spans roughly 0.95 Earth radii and weighs about 0.82 Earth masses.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, TOI-700 e is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why TOI-700 e is an epic exoplanet

TOI-700 e scores 61 points on Spacedle's rarity scale, which places it in the epic tier. Another 7 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Earth-sized, Multi-planet system and Found by TESS — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
