Pi Orionis (π Ori / π Orionis), formally designated Tabit, is a white F-type dwarf star approximately 26 light-years away in the constellation of Orion. It is thought that the star may, in fact, be a binary star system. Though no extrasolar planets have been observed around Pi Orionis, the star is considered a prime location for planets as small as the Earth. Pi Orionis is the brightest star in the lion's hide (or shield) that Orion is holding.

Pi Orionis (π Ori / π Orionis), formally designated Tabit, is a white F-type dwarf star approximately 26 light-years away in the constellation of Orion. It is thought that the star may, in fact, be a binary star system.

Pi Orionis is the brightest star in the lion's hide (or shield) that Orion is holding.
Pi Orionis is a dwarf star of spectral type F6V. It has been calculated that the star has 1.3 times the mass of the Sun, 1.6 times the radius, and 3 times the luminosity. The star may have anywhere from 20 to 151 percent of the Sun's enrichment in elements heavier than hydrogen (based on its abundance of iron). It is thought that Pi Orionis has a companion star, but the purported companion "B" may not in fact be part of the system.
Although a periodicity of 73.26 days has been observed in star's radial velocity, it seems likely bound more to...
