Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 9.1 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 811 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 5194 years in a starship at a tenth of light speed.
- Distance. 519 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1507.
Saying hello
- Say hello. A radio message and its reply would take 1039 years round-trip.
Standing on it
- A year here. A full year lasts just 28.2 Earth days.
By the numbers
- Size. About 1.9× the width of Earth.
- Volume. About 6.5 Earths could fit inside it.
- Mass. About 4.2× the mass of Earth.
- Your weight. You'd weigh about 1.2× your Earth weight standing here.
How we found it
- Discovery. Found by K2 using the transit method.

Why EPIC 201238110 b is a trash exoplanet
EPIC 201238110 b scores 13 points on Spacedle's rarity scale, which places it in the trash tier. Another 2 points would lift it into a rarer tier.
That score comes from 2 science badges — Confirmed exoplanet and Super-Earth — 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.
