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. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 7.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 702.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4498 years in a starship at a tenth of light speed.
Distance. 450 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1576.

Saying hello

Say hello. A radio message and its reply would take 900 years round-trip.

By the numbers

Size. About 12.2× the width of Earth.
Volume. About 1816 Earths could fit inside it.
Mass. Roughly 5085× Earth's mass — about 16 Jupiters.
Your weight. You'd weigh about 34.2× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 2270 K — hot enough to vaporise iron.

How we found it

Discovery. Found by Multiple Observatories using the imaging method.

About USco1621 b

USco1621 b is an anomaly exoplanet. It lies about 449.8 light-years from Earth, has an equilibrium temperature near 2,270 K, spans roughly 12.2 Earth radii and weighs about 5,085.28 Earth masses.

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

How to see it

Like any astronomical target, USco1621 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 USco1621 b is an anomaly exoplanet

USco1621 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 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Denser than iron 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.
