DENIS-P J082303.1-491201 b
A confirmed world orbiting DENIS-P J082303.1-491201, 67.7 light-years away.
A gas giant
11.90 Earth radii, Jupiter-class (Jupiter is 11.2). With 9057.8 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 246 Earth days (0.7 Earth years). The orbit is strongly stretched (eccentricity 0.34), so its distance from the star, and with it the climate, swings dramatically.
How far is that, really?
At 68 light-years, tonight's light from this system left it around the year 1958. A Voyager-speed probe would need roughly 1,198,544 years to get there.
How we found it
It was found by astrometry, which measures the star's tiny sideways drift across the sky. The discovery was announced in 2013 from Paranal 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.
