Trivia
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 1.6 million years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 144.9 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 928 years in a starship at a tenth of light speed.
- Distance. 92.8 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 1933.
Saying hello
- Say hello. A radio message and its reply would take 186 years round-trip.
Standing on it
- A year here. A full year lasts just 70 Earth days.
By the numbers
- Size. About 4.2× the width of Earth.
- Volume. About 72.5 Earths could fit inside it.
- Mass. About 16.2× the mass of Earth.
- Your weight. You'd weigh about 0.9× your Earth weight standing here.
- Temperature. A surprisingly temperate 38°C average.
How we found it
- Discovery. Found by Multiple Observatories using the radial velocity method.

How to see it
Like any astronomical target, GJ 2056 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 GJ 2056 b is a common exoplanet
GJ 2056 b scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 6 points would lift it into a rarer tier.
That score comes from 3 science badges — Confirmed exoplanet, Neptune-like and Eccentric orbit — 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.
