Trivia

What makes it special

  • Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 8.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 758.4 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 4857 years in a starship at a tenth of light speed.
  • Distance. 486 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1540.

Saying hello

  • Say hello. A radio message and its reply would take 971 years round-trip.

Standing on it

  • A year here. A full year lasts just 2.7 Earth days.

By the numbers

  • Size. About 16.7× the width of Earth.
  • Volume. About 4659 Earths could fit inside it.
  • Mass. Roughly 992× Earth's mass — about 3.1 Jupiters.
  • Your weight. You'd weigh about 3.6× your Earth weight standing here.
  • Temperature. Around 2370 K — hot enough to vaporise iron.

How we found it

  • Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit method.

About TOI-1431 b

TOI-1431 b is an epic exoplanet. It lies about 485.7 light-years from Earth, has an equilibrium temperature near 2,370 K, spans roughly 16.7 Earth radii and weighs about 991.62 Earth masses.

So hot that iron vaporises and rains back down as molten metal.

How to see it

Like any astronomical target, TOI-1431 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 TOI-1431 b is an epic exoplanet

TOI-1431 b scores 57 points on Spacedle's rarity scale, which places it in the epic tier. Another 11 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Blasted by starlight and Found by TESS — 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.
