Orbit and Year Length
A year on DENIS-P J082303.1-491201 b — one full orbit around DENIS-P J082303.1-491201 — lasts 246.4 Earth days, between the years of Mercury (88 days) and Earth (365 days). It orbits at an average distance of 0.360 AU — closer to its star than Mercury is to the Sun. Its orbit is highly elliptical (eccentricity 0.35), swinging dramatically closer to and farther from its star.
How Was DENIS-P J082303.1-491201 b Discovered?
DENIS-P J082303.1-491201 b was discovered in 2013 using the astrometry method, with observations from Paranal Observatory.
Astrometry detects a planet by measuring the tiny periodic shift in a star's position on the sky as the star and planet orbit their common center of mass.
