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. ≈ 8.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 731.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4683 years in a starship at a tenth of light speed.
Distance. 468 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1558.

Saying hello

Say hello. A radio message and its reply would take 937 years round-trip.

By the numbers

Size. About 12.5× the width of Earth.
Volume. About 1953 Earths could fit inside it.
Mass. Roughly 2860× Earth's mass — about 9 Jupiters.
Your weight. You'd weigh about 18.3× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 1702°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Multiple Observatories using the imaging method.

About ROXs 42 B b

ROXs 42 B b is an anomaly exoplanet. It lies about 468.3 light-years from Earth, has an equilibrium temperature near 1,975 K, spans roughly 12.5 Earth radii and weighs about 2,860 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, ROXs 42 B 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 ROXs 42 B b is an anomaly exoplanet

ROXs 42 B b scores 76 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 19 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Eccentric orbit, 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.
