Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 9.9 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 877.2 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 5618 years in a starship at a tenth of light speed.
- Distance. 562 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1464.
Saying hello
- Say hello. A radio message and its reply would take 1124 years round-trip.
Standing on it
- A year here. A full year lasts just 0.4 Earth days.
By the numbers
- Size. Around 51% of Earth's width.
- Mass. Roughly 99.2× Earth's mass — about 0.3 Jupiters.
- Your weight. You'd weigh about 381.4× your Earth weight standing here.
- Temperature. Around 907°C — hotter than a self-cleaning oven.
How we found it
- Discovery. Found by Kepler using the transit method.

Why KOI-4777.01 is a common exoplanet
KOI-4777.01 scores 22 points on Spacedle's rarity scale, which places it in the common tier. Another 2 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Ultra-short period 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.
