Confirmed exoplanet · Database record + computed analysis
LkCa 15 c
A confirmed world orbiting LkCa 15, 515.8 light-years away.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about -214 °C. Deep-freeze territory, colder than Antarctica's worst. It receives only 0.00 times Earth's starlight.
Its sun
Its star is an orange K-type (4,194 K): cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability. It shares the system with 1 other known planet.
How far is that, really?
At 516 light-years, tonight's light from this system left it around the year 1510. A Voyager-speed probe would need roughly 9,126,243 years to get there.
How we found it
It was directly imaged, one of the rare planets actually photographed as its own point of light, possible only for young, hot, wide-orbiting giants. The discovery was announced in 2015 from Large Binocular Telescope 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.
