Trivia

What makes it special

  • Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.
  • 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. ≈ 29.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.6 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 16.8 thousand years in a starship at a tenth of light speed.
  • Distance. 1682 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 344.

Saying hello

  • Say hello. A radio message and its reply would take 3363 years round-trip.

Standing on it

  • A year here. A full year lasts just 4 Earth days.

By the numbers

  • Size. About 13.7× the width of Earth.
  • Volume. About 2557 Earths could fit inside it.
  • Mass. Roughly 7024× Earth's mass — about 22.1 Jupiters.
  • Your weight. You'd weigh about 37.6× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. Around 2290 K — hot enough to vaporise iron.

How we found it

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

About TOI-1994 b

TOI-1994 b is an anomaly exoplanet. It lies about 1,681.7 light-years from Earth, has an equilibrium temperature near 2,290 K, spans roughly 13.67 Earth radii and weighs about 7,024.01 Earth masses.

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

How to see it

Like any astronomical target, TOI-1994 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-1994 b is an anomaly exoplanet

TOI-1994 b scores 85 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 10 points would lift it into a rarer tier.

That score comes from 8 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Denser than iron, Blasted by starlight, Found by TESS 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.
