Trivia

What makes it special

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. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 240.4 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 1539 years in a starship at a tenth of light speed.
Distance. 154 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1872.

Saying hello

Say hello. A radio message and its reply would take 308 years round-trip.

By the numbers

Size. About 12.3× the width of Earth.
Volume. About 1861 Earths could fit inside it.
Mass. Roughly 4132× Earth's mass — about 13 Jupiters.
Your weight. You'd weigh about 27.3× your Earth weight standing here.
Density. Denser than solid iron.

How we found it

Discovery. Found by Paranal Observatory using the imaging method.

Why 2MASS J01033563-5515561 AB b is a rare exoplanet

2MASS J01033563-5515561 AB b scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 3 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, 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.
