Lambda Pictoris

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]
