Confirmed exoplanet · Database record + computed analysis
omi CrB b
A confirmed world orbiting omi CrB, 276.5 light-years away.
A gas giant
13.70 Earth radii, Jupiter-class (Jupiter is 11.2). At only 356.0 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
The orbit
Its year takes 187 Earth days (0.5 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 674 °C. Hotter than Venus's surface. It receives 135.8 times the starlight Earth gets.
Its sun
Its star is an orange K-type (4,769 K), K0 III: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 277 light-years, tonight's light from this system left it around the year 1749. A Voyager-speed probe would need roughly 4,892,753 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 2012 from Okayama Astrophysical 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.
