Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 4.4 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 395 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 2530 years in a starship at a tenth of light speed.
- Distance. 253 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1773.
Saying hello
- Say hello. A radio message and its reply would take 506 years round-trip.
Standing on it
- A year here. A full year lasts just 7.8 Earth days.
By the numbers
- Size. Around 70% of Earth's width.
- Mass. About 0.3× the mass of Earth.
- Your weight. You'd weigh about 0.6× your Earth weight standing here.
- Temperature. A scorching 391°C on average.
How we found it
- Discovery. Found by K2 using the transit method.
Cosmic context
- Crowded system. One of at least 4 planets orbiting its star.

How to see it
Like any astronomical target, K2-266 c 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 K2-266 c is a trash exoplanet
K2-266 c scores 11 points on Spacedle's rarity scale, which places it in the trash tier. Another 4 points would lift it into a rarer tier.
That score comes from 2 science badges — Confirmed exoplanet and Multi-planet system — 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.
