Trivia

What makes it special

  • Heavyweight. Packed denser than solid iron.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 413.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 36.7 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 235.2 thousand years in a starship at a tenth of light speed.
  • Distance. 23.5 thousand light-years from Earth.

Look-back time

  • Look-back time. This light set out before Homo sapiens existed.

Saying hello

  • Say hello. A radio message and its reply would take 47 thousand years round-trip.

By the numbers

  • Size. About 11.9× the width of Earth.
  • Volume. About 1685 Earths could fit inside it.
  • Mass. Roughly 8658× Earth's mass — about 27.2 Jupiters.
  • Your weight. You'd weigh about 61.1× your Earth weight standing here.
  • Density. Denser than solid iron.

How we found it

  • Discovery. Found by KMTNet using the microlensing method.

Cosmic context

  • Crowded system. One of at least 2 planets orbiting its star.

Why KMT-2024-BLG-0404L b is an epic exoplanet

KMT-2024-BLG-0404L b scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 13 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Denser than iron, Multi-planet system, Found by microlensing 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.
