Trivia

What makes it special

  • Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 16.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 9486 years in a starship at a tenth of light speed.
  • Distance. 949 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1077.

Saying hello

  • Say hello. A radio message and its reply would take 1897 years round-trip.

Standing on it

  • A year here. A full year lasts just 1.3 Earth days.

By the numbers

  • Size. About 1.2× the width of Earth.
  • Mass. About 2× the mass of Earth.
  • Your weight. You'd weigh about 1.3× your Earth weight standing here.
  • Temperature. Around 1510°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Kepler using the transit method.

About Kepler-908 b

Kepler-908 b is an epic exoplanet. It lies about 948.6 light-years from Earth, has an equilibrium temperature near 1,783 K, spans roughly 1.22 Earth radii and weighs about 1.98 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, Kepler-908 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-908 b is an epic exoplanet

Kepler-908 b scores 46 points on Spacedle's rarity scale, which places it in the epic tier. Another 22 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Earth-sized, Lava world, Blasted by starlight 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.
