Trivia

What makes it special

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

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 71.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 6.4 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 40.8 thousand years in a starship at a tenth of light speed.
  • Distance. 4075 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 8150 years round-trip.

Standing on it

  • A year here. A full year lasts just 5 Earth days.

By the numbers

  • Size. About 15× the width of Earth.
  • Volume. About 3348 Earths could fit inside it.
  • Temperature. Around 1035°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Kepler using the transit method.

About Kepler-471 b

Kepler-471 b is an epic exoplanet. It lies about 4,075 light-years from Earth, has an equilibrium temperature near 1,308 K, spans roughly 14.96 Earth radii and completes an orbit every 5.01 days.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, Kepler-471 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-471 b is an epic exoplanet

Kepler-471 b scores 54 points on Spacedle's rarity scale, which places it in the epic tier. Another 14 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Blasted by starlight, Found by Kepler 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.
