Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 61.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 5.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 35 thousand years in a starship at a tenth of light speed.
  • Distance. 3497 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 6995 years round-trip.

Standing on it

  • A year here. A full year lasts just 75.2 Earth days.

By the numbers

  • Size. About 2.4× the width of Earth.
  • Volume. About 13.8 Earths could fit inside it.
  • Mass. About 6.3× the mass of Earth.
  • Your weight. You'd weigh about 1.1× your Earth weight standing here.

How we found it

  • Discovery. Found by Kepler using the transit method.

Cosmic context

  • Crowded system. One of at least 3 planets orbiting its star.

Why KIC 8540376 c is an uncommon exoplanet

KIC 8540376 c scores 29 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Sub-Neptune, Multi-planet system, 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.
