Trivia

What makes it special

  • Lava world. Its surface is likely an ocean of molten rock.
  • Cotton-candy planet. So low-density it would float on water.

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 50.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 4.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 28.8 thousand years in a starship at a tenth of light speed.
  • Distance. 2878 light-years from Earth.

Look-back time

  • Look-back time. Its light left before the last ice age ended.

Saying hello

  • Say hello. A radio message and its reply would take 5756 years round-trip.

Standing on it

  • A year here. A full year lasts just 4 Earth days.

By the numbers

  • Size. About 15.6× the width of Earth.
  • Volume. About 3766 Earths could fit inside it.
  • Mass. Roughly 148× Earth's mass — about 0.5 Jupiters.
  • Your weight. You'd weigh about 0.6× your Earth weight standing here.
  • Density. Less dense than water — drop it in a big enough ocean and it would float.
  • Temperature. Around 1165°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by CoRoT using the transit method.

About CoRoT-5 b

CoRoT-5 b is an epic exoplanet. It lies about 2,878.2 light-years from Earth, has an equilibrium temperature near 1,438 K, spans roughly 15.56 Earth radii and weighs about 148.42 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, CoRoT-5 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-5 b is an epic exoplanet

CoRoT-5 b scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 13 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Lava world, Puffy low-density world and Distant (>1000 ly) — 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.
