Trivia

What makes it special

  • Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 103.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 9.2 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 58.7 thousand years in a starship at a tenth of light speed.
  • Distance. 5873 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 11.7 thousand years round-trip.

Standing on it

  • A year here. A full year lasts just 289 Earth days.

By the numbers

  • Size. About 8.6× the width of Earth.
  • Volume. About 628 Earths could fit inside it.
  • Mass. Roughly 69.9× Earth's mass — about 0.2 Jupiters.
  • Your weight. You'd weigh about 1.0× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. A surprisingly temperate 21°C average.

How we found it

  • Discovery. Found by Kepler using the transit method.

About Kepler-34 b

Kepler-34 b is an epic exoplanet. It lies about 5,873.5 light-years from Earth, has an equilibrium temperature near 294 K, spans roughly 8.56 Earth radii and weighs about 69.92 Earth masses.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, Kepler-34 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-34 b is an epic exoplanet

Kepler-34 b scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 16 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, In the habitable zone, Gas giant, 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.
