Trivia
Could we get there?
- Verdict. Impossible with our current technology — and the next millennium of it.
Getting there
- Aboard Voyager 1. ≈ 40.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 3.6 million years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 23 thousand years in a starship at a tenth of light speed.
- Distance. 2304 light-years from Earth.
Look-back time
- Look-back time. Its light left before the last ice age ended.
Saying hello
- Say hello. A radio message and its reply would take 4608 years round-trip.
Standing on it
- A year here. A full year lasts just 0.7 Earth days.
By the numbers
- Size. About 1.5× the width of Earth.
- Mass. About 2.9× the mass of Earth.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
How we found it
- Discovery. Found by K2 using the transit method.

Why EPIC 201427007 b is a rare exoplanet
EPIC 201427007 b scores 37 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.
That score comes from 4 science badges — Confirmed exoplanet, Super-Earth, Ultra-short period and Distant (>1000 ly) — 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.
