beta Pic b
beta Pic b
beta Pic b is an exoplanet orbiting the star beta Pic, located about 63.4 light-years (19.4 pc) away from Solar System. Its discovery was publicly announced on 2008.
The host star beta Pic has apparent magnitude of 3.9, with absolute magnitude of 2.4. It is 1.7 times more massive and 1.4 times bigger compared with our Sun. The surface temperature is 8100 with its spectral types of A6V
In this planetary system, the extrasolar planet beta Pic b orbits around the star beta Pic every 7707.0 days with its orbital distance of 9.93 AU ( 1485506856.1 km)

: 2.018 AU ( 301857778.9 km)
Earth Boundary (the orbital distance at Earth's Equivalent Radiation)
: 2.789 AU ( 417246335.2 km)
Outer Boundary (the orbital distance at Mars's Equivalent Radiation)
: 4.250 AU ( 635791078.5 km)
Snow Line (the orbital distance at Snow Line Equivalent Radiation)
: 6.254 AU ( 935594424.2 km)
