Trivia

What makes it special

Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.
Cotton-candy planet. So low-density it would float on water.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 21.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.9 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 12.4 thousand years in a starship at a tenth of light speed.
Distance. 1237 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 789.

Saying hello

Say hello. A radio message and its reply would take 2474 years round-trip.

Standing on it

A year here. A full year lasts just 3.4 Earth days.

By the numbers

Size. About 17.4× the width of Earth.
Volume. About 5244 Earths could fit inside it.
Mass. Roughly 200× Earth's mass — about 0.6 Jupiters.
Your weight. You'd weigh about 0.7× your Earth weight standing here.
Density. Less dense than water — drop it in a big enough ocean and it would float.
Temperature. Around 2410 K — hot enough to vaporise iron.

How we found it

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

About TOI-2580 b

TOI-2580 b is an anomaly exoplanet. It lies about 1,237 light-years from Earth, has an equilibrium temperature near 2,410 K, spans roughly 17.37 Earth radii and weighs about 200.23 Earth masses.

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

How to see it

Like any astronomical target, TOI-2580 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-2580 b is an anomaly exoplanet

TOI-2580 b scores 79 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 16 points would lift it into a rarer tier.

That score comes from 8 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Puffy low-density world, 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.
