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. ≈ 7.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 693.4 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 4441 years in a starship at a tenth of light speed.
Distance. 444 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1582.

Saying hello

Say hello. A radio message and its reply would take 888 years round-trip.

Standing on it

A year here. A full year lasts about 20 thousand Earth years.

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. Around 2175 K — hot enough to vaporise iron.

How we found it

Discovery. Found by Gemini Observatory using the imaging method.

About Oph 11 b

Oph 11 b is an anomaly exoplanet. It lies about 444.1 light-years from Earth, has an equilibrium temperature near 2,175 K, spans roughly 12.3 Earth radii and weighs about 4,449.62 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, Oph 11 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 Oph 11 b is an anomaly exoplanet

Oph 11 b scores 77 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 18 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Long-period 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.
