Trivia
What makes it special
- Frozen world. A deep-frozen world far from its star's warmth.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 10.5 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 930.5 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 5959 years in a starship at a tenth of light speed.
- Distance. 596 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1430.
Saying hello
- Say hello. A radio message and its reply would take 1192 years round-trip.
Standing on it
- A year here. A full year lasts about 13.3 Earth years.
By the numbers
- Size. About 12.6× the width of Earth.
- Volume. About 2000 Earths could fit inside it.
- Mass. Roughly 2476× Earth's mass — about 7.8 Jupiters.
- Your weight. You'd weigh about 15.6× your Earth weight standing here.
- Temperature. A frigid -174°C — colder than dry ice.
How we found it
- Discovery. Found by Roque de los Muchachos Observatory using the radial velocity method.
Cosmic context
- Crowded system. One of at least 2 planets orbiting its star.

How to see it
Like any astronomical target, Pr0211 c 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 Pr0211 c is a rare exoplanet
Pr0211 c scores 42 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.
That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Frozen world, Long-period world, Eccentric orbit and Multi-planet system — 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.
