Trivia
What makes it special
- Packed system. Crammed into a system of five or more planets.
Could we get there?
- Verdict. Hopelessly far for any craft humanity can build today.
Getting there
- Aboard Voyager 1. ≈ 415.2 thousand years at Voyager 1's speed (17 km/s).
- Fastest probe ever. ≈ 36.9 thousand years even at the Parker Solar Probe's 192 km/s.
- At 10% light speed. ≈ 236 years in a starship at a tenth of light speed.
- Distance. 23.6 light-years from Earth.
Look-back time
- Look-back time. The light you'd see left around the year 2002.
Saying hello
- Say hello. A radio message and its reply would take 47.3 years round-trip.
Standing on it
- A year here. A full year lasts just 62.2 Earth days.
By the numbers
- Size. About 1.4× the width of Earth.
- Mass. About 2.7× the mass of Earth.
- Your weight. You'd weigh about 1.3× your Earth weight standing here.
How we found it
- Discovery. Found by La Silla Observatory using the radial velocity method.
Cosmic context
- Crowded system. One of at least 5 planets orbiting its star.

How to see it
Like any astronomical target, GJ 667 C e 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 667 C e is a rare exoplanet
GJ 667 C e scores 45 points on Spacedle's rarity scale, which places it in the rare tier. Another 1 point would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Super-Earth, Multi-planet system, Richly packed system and Nearby (<25 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.
