Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 55.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 4.9 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 31.4 thousand years in a starship at a tenth of light speed.
  • Distance. 3141 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 6283 years round-trip.

Standing on it

  • A year here. A full year lasts just 21.4 Earth days.

By the numbers

  • Size. About 2.1× the width of Earth.
  • Volume. About 9.5 Earths could fit inside it.
  • Mass. About 5.1× the mass of Earth.
  • Your weight. You'd weigh about 1.1× your Earth weight standing here.
  • Temperature. Around 475°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Kepler using the transit method.

About Kepler-544 b

Kepler-544 b is a common exoplanet. It lies about 3,141.5 light-years from Earth, has an equilibrium temperature near 748 K, spans roughly 2.12 Earth radii and weighs about 5.14 Earth masses.

About 2.1× the width of Earth.

How to see it

Like any astronomical target, Kepler-544 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-544 b is a common exoplanet

Kepler-544 b scores 23 points on Spacedle's rarity scale, which places it in the common tier. Another 1 point would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Sub-Neptune, 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.
