Trivia

What makes it special

Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 12.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 1.1 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 6956 years in a starship at a tenth of light speed.
Distance. 696 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1330.

Saying hello

Say hello. A radio message and its reply would take 1391 years round-trip.

Standing on it

A year here. A full year lasts just 1.7 Earth days.

By the numbers

Size. About 16.4× the width of Earth.
Volume. About 4437 Earths could fit inside it.
Mass. Roughly 1103× Earth's mass — about 3.5 Jupiters.
Your weight. You'd weigh about 4.1× your Earth weight standing here.
Temperature. Around 1248°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by CoRoT using the transit method.

About CoRoT-2 b

CoRoT-2 b is a rare exoplanet. It lies about 695.6 light-years from Earth, has an equilibrium temperature near 1,521 K, spans roughly 16.43 Earth radii and weighs about 1,102.82 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, CoRoT-2 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 CoRoT-2 b is a rare exoplanet

CoRoT-2 b scores 33 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter and Lava world — 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.
