Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 1.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 133 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 852 years in a starship at a tenth of light speed.
- Distance. 85.2 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1941.
Saying hello
- Say hello. A radio message and its reply would take 170 years round-trip.
Standing on it
- A year here. A full year lasts just 4.7 Earth days.
By the numbers
- Size. About 1.9× the width of Earth.
- Volume. About 7.2 Earths could fit inside it.
- Mass. About 5.1× the mass of Earth.
- Your weight. You'd weigh about 1.4× your Earth weight standing here.
- Temperature. A scorching 278°C on average.
How we found it
- Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

How to see it
Like any astronomical target, TOI-912 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-912 b is an uncommon exoplanet
TOI-912 b scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Super-Earth, Eccentric orbit 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.
