Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 8.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 764.5 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 4896 years in a starship at a tenth of light speed.
- Distance. 490 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1536.
Saying hello
- Say hello. A radio message and its reply would take 979 years round-trip.
Standing on it
- A year here. A full year lasts just 0.7 Earth days.
By the numbers
- Size. About 1.1× the width of Earth.
- Mass. About 1.4× the mass of Earth.
- Your weight. You'd weigh about 1.1× your Earth weight standing here.
- Temperature. Around 659°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by K2 using the transit method.

Why EPIC 228836835 b is a rare exoplanet
EPIC 228836835 b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Earth-sized and Ultra-short period — 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.
