Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 1.3 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 117.6 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 753 years in a starship at a tenth of light speed.
  • Distance. 75.3 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1951.

Saying hello

  • Say hello. A radio message and its reply would take 151 years round-trip.

Standing on it

  • A year here. A full year lasts about 27.5 Earth years.

By the numbers

  • Size. About 12.4× the width of Earth.
  • Volume. About 1907 Earths could fit inside it.
  • Mass. Roughly 3337× Earth's mass — about 10.5 Jupiters.
  • Your weight. You'd weigh about 21.7× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A scorching 97°C on average.

How we found it

  • Discovery. Found by W. M. Keck Observatory using the imaging method.

Why CFBDSIR J145829+101343 b is an epic exoplanet

CFBDSIR J145829+101343 b scores 53 points on Spacedle's rarity scale, which places it in the epic tier. Another 15 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Long-period world, Denser than iron and Directly imaged — 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.
