Confirmed exoplanet · Database record + computed analysis
RR Cae b
A confirmed world orbiting RR Cae, 69.1 light-years away.
A gas giant
13.00 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year takes 4,344 Earth days (11.9 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about -237 °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 (3,904 K), M: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability. The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 69 light-years, tonight's light from this system left it around the year 1956. A Voyager-speed probe would need roughly 1,222,872 years to get there.
How we found it
It was inferred from eclipse timing variations in its binary star system. The discovery was announced in 2012 from Leoncito Astronomical Complex.
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.
