Confirmed exoplanet · Database record + computed analysis
GJ 667 C e
A confirmed world orbiting GJ 667 C, 23.6 light-years away.
A super-Earth
1.45 Earth radii. Worlds between Earth and Neptune in size are the most common in the galaxy, yet our Solar System has none, which is why each one matters.
The orbit
Its year, one full orbit, takes just 62.2 Earth days.
Temperature and starlight
It receives 0.30 times Earth's starlight, the same order as our own world.
Its sun
Its star is a red dwarf (3,350 K surface), type M1.5 V: small, dim, flare-prone, and destined to outlive the Sun many times over. The system holds 3 stars, so its skies have more than one sun. It shares the system with 4 other known planets.
How far is that, really?
At 24 light-years, tonight's light from this system left it around the year 2002. That is close by galactic standards, which makes it a prime target for follow-up telescopes. A Voyager-speed probe would need roughly 418,016 years to get there.
How we found it
It was found by the radial-velocity method: the planet's gravity swings its star in a small circle, and that wobble shows up as a rhythmic Doppler shift in the starlight. The wobble's size gives the planet's minimum mass. The discovery was announced in 2013 from La Silla Observatory.
Everything above is computed from the archive’s measured values for this planet. Where a quantity is missing, the statement is omitted rather than guessed.
About this record
The measured values come from the NASA Exoplanet Archive, and any missing value has not been determined yet; the Atlas never fills gaps with guesses. More standout worlds: Proxima b, TRAPPIST-1e, K2-18 b, 55 Cancri e, and the detection methods that found them all.
