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. ≈ 37.5 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 3.3 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 21.4 thousand years in a starship at a tenth of light speed.
Distance. 2136 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 4273 years round-trip.

Standing on it

A year here. A full year lasts just 1.7 Earth days.

By the numbers

Size. About 16.5× the width of Earth.
Volume. About 4474 Earths could fit inside it.
Mass. Roughly 6261× Earth's mass — about 19.7 Jupiters.
Your weight. You'd weigh about 23.1× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 2300 K — hot enough to vaporise iron.

How we found it

Discovery. Found by Acton Sky Portal Observatory using the transit method.

About GPX-1 b

GPX-1 b is an anomaly exoplanet. It lies about 2,136.4 light-years from Earth, has an equilibrium temperature near 2,300 K, spans roughly 16.48 Earth radii and weighs about 6,261.22 Earth masses.

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

How to see it

Like any astronomical target, GPX-1 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 GPX-1 b is an anomaly exoplanet

GPX-1 b scores 81 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 14 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Denser than iron, Blasted by starlight 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.
