AB Pic b
AB Pic b is a exoplanet orbiting the K2 V star AB Pic in the constellation Pictor. It lies about 163 light-years from Earth and was discovered in 2005 using the imaging method.
Is AB Pic b in the Habitable Zone?
The position of AB Pic b relative to the habitable zone of AB Pic cannot be precisely determined from the available orbital data.
Orbit and Year Length
AB Pic b orbits at an average distance of 260.000 AU.
How Was AB Pic b Discovered?
AB Pic b was discovered in 2005 using the imaging method, with observations from Paranal Observatory.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is AB Pic b?
AB Pic b is 163.2 light-years (50.0 parsecs) from Earth. Light arriving here tonight left the planet around the year 1863. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 2,872,320 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. AB Pic b scores 0.07, ranking #4,881 of 5,568 planets with a known ESI. For reference, Mars scores about 0.70.
