Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 3.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 327.5 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 2097 years in a starship at a tenth of light speed.
  • Distance. 210 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1816.

Saying hello

  • Say hello. A radio message and its reply would take 419 years round-trip.

By the numbers

  • Size. About 15.7× the width of Earth.
  • Volume. About 3864 Earths could fit inside it.
  • Mass. Roughly 1653× Earth's mass — about 5.2 Jupiters.
  • Your weight. You'd weigh about 6.7× your Earth weight standing here.
  • Temperature. Around 890°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Paranal Observatory using the imaging method.

Why 2MASS J12073346-3932539 b is a rare exoplanet

2MASS J12073346-3932539 b scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter 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.
