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. ≈ 2.9 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 254.8 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1632 years in a starship at a tenth of light speed.
  • Distance. 163 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1863.

Saying hello

  • Say hello. A radio message and its reply would take 326 years round-trip.

Standing on it

  • A year here. A full year lasts just 18.8 Earth days.

By the numbers

  • Size. About 1.9× the width of Earth.
  • Volume. About 6.9 Earths could fit inside it.
  • Mass. About 4.3× the mass of Earth.
  • Your weight. You'd weigh about 1.2× your Earth weight standing here.
  • Temperature. A surprisingly temperate 3°C average.

How we found it

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

About TOI-2094 b

TOI-2094 b is an epic exoplanet. It lies about 163.2 light-years from Earth, has an equilibrium temperature near 276 K, spans roughly 1.9 Earth radii and weighs about 4.27 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-2094 b 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-2094 b is an epic exoplanet

TOI-2094 b scores 47 points on Spacedle's rarity scale, which places it in the epic tier. Another 21 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, In the habitable zone, Super-Earth 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.
