Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 11.1 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 988.1 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 6329 years in a starship at a tenth of light speed.
- Distance. 633 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1393.
Saying hello
- Say hello. A radio message and its reply would take 1266 years round-trip.
Standing on it
- A year here. A full year lasts just 9.4 Earth days.
By the numbers
- Size. About 6.1× the width of Earth.
- Volume. About 228 Earths could fit inside it.
- Mass. Roughly 120× Earth's mass — about 0.4 Jupiters.
- Your weight. You'd weigh about 3.2× your Earth weight standing here.
- Temperature. Around 518°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Kepler using the transit method.

How to see it
Like any astronomical target, Kepler-63 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 Kepler-63 b is a trash exoplanet
Kepler-63 b scores 12 points on Spacedle's rarity scale, which places it in the trash tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Found by Kepler — 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.
