Trivia

What makes it special

Goldilocks zone. Sits where it's neither too hot nor too cold — liquid water could exist.
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 28.1 Earth days.

By the numbers

Size. About 1.8× the width of Earth.
Volume. About 5.5 Earths could fit inside it.
Mass. About 3.8× the mass of Earth.
Your weight. You'd weigh about 1.2× 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.

Nearby objects

About GJ 667 C c

GJ 667 C c is an anomaly exoplanet. It lies about 23.6 light-years from Earth, spans roughly 1.77 Earth radii, weighs about 3.8 Earth masses and completes an orbit every 28.14 days.

Sits where it's neither too hot nor too cold — liquid water could exist.

How to see it

Like any astronomical target, GJ 667 C 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 GJ 667 C c is an anomaly exoplanet

GJ 667 C c scores 75 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 20 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, In the habitable zone, 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.
