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. ≈ 9.2 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 814.3 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 5215 years in a starship at a tenth of light speed.
Distance. 522 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1504.

Saying hello

Say hello. A radio message and its reply would take 1043 years round-trip.

Standing on it

A year here. A full year lasts just 0.9 Earth days.

By the numbers

Size. About 1.7× the width of Earth.
Volume. About 4.8 Earths could fit inside it.
Mass. About 4.1× the mass of Earth.
Your weight. You'd weigh about 1.4× your Earth weight standing here.
Density. Denser than solid iron.
Temperature. Around 1483°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by CoRoT using the transit method.

Cosmic context

Crowded system. One of at least 3 planets orbiting its star.

About CoRoT-7 b

CoRoT-7 b is an anomaly exoplanet. It lies about 521.5 light-years from Earth, has an equilibrium temperature near 1,756 K, spans roughly 1.68 Earth radii and weighs about 4.08 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, CoRoT-7 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-7 b is an anomaly exoplanet

CoRoT-7 b scores 73 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 22 points would lift it into a rarer tier.

That score comes from 7 science badges — Confirmed exoplanet, Super-Earth, Lava world, Ultra-short period, Denser than iron, Multi-planet system and Blasted by starlight — 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.
