Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.
  • JWST find. Discovered by the James Webb Space Telescope.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 827.1 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 73.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 471 years in a starship at a tenth of light speed.
  • Distance. 47.1 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1979.

Saying hello

  • Say hello. A radio message and its reply would take 94.1 years round-trip.

By the numbers

  • Size. About 12.2× the width of Earth.
  • Volume. About 1816 Earths could fit inside it.
  • Mass. Roughly 4926× Earth's mass — about 15.5 Jupiters.
  • Your weight. You'd weigh about 33.1× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. A scorching 117°C on average.

How we found it

  • Discovery. Found by James Webb Space Telescope (JWST) using the imaging method.

Why CWISEP J193518.59-154620.3 b is an epic exoplanet

CWISEP J193518.59-154620.3 b scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 5 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Denser than iron, Found by JWST 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.
