Trivia

What makes it special

Frozen world. A deep-frozen world far from its star's warmth.
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. ≈ 8.3 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 733.4 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4697 years in a starship at a tenth of light speed.
Distance. 470 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1556.

Saying hello

Say hello. A radio message and its reply would take 939 years round-trip.

By the numbers

Size. About 12.3× the width of Earth.
Volume. About 1861 Earths could fit inside it.
Mass. Roughly 4450× Earth's mass — about 14 Jupiters.
Your weight. You'd weigh about 29.4× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. A frigid -270°C — colder than dry ice.

How we found it

Discovery. Found by Teide Observatory using the imaging method.

Why USco CTIO 108 b is an epic exoplanet

USco CTIO 108 b scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 17 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Gas giant, Frozen world, 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.
