Lambda Pictoris
Star in the constellation Pictor
λ Pictoris , Latinised as Lambda Pictoris , is a solitary,[ 7] orange-hued star in the southern constellation of Pictor . It is visible to the naked eye, having an apparent visual magnitude of +5.29.[ 2] With an annual parallax shift of 8.71[ 1] mas as seen from the Earth, it is located around 374 light-years from the Sun . At the estimated age of 2.24[ 4] billion years old, it is an evolved K-type giant star with a stellar classification of K0/1 III.[ 3] Lambda Pictoris has 2.2 times the mass of the Sun and is radiating 112 times the Sun's luminosity from its photosphere at an effective temperature of 4,581 K .[ 4]
