Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.
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. ≈ 3.3 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 291.5 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1867 years in a starship at a tenth of light speed.
Distance. 187 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1839.

Saying hello

Say hello. A radio message and its reply would take 373 years round-trip.

By the numbers

Size. About 11.9× the width of Earth.
Volume. About 1685 Earths could fit inside it.
Mass. Roughly 9535× Earth's mass — about 30 Jupiters.
Your weight. You'd weigh about 67.3× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 1327°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by The 2 (Two) Micron All Sky Survey (2MASS) using the imaging method.

Why 2MASS J22501512+2325342 b is an epic exoplanet

2MASS J22501512+2325342 b scores 67 points on Spacedle's rarity scale, which places it in the epic tier. Another 1 point would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava 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.
