HD 196050
HD 196050 is a triple star system located in the southern constellation of Pavo. This system has an apparent magnitude of 7.50 and the absolute magnitude is 4.01. It is located at a distance of 112 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +61 km/s. It is also called by the Hipparcos number 101806.
The primary component is a G-type main-sequence star with a stellar classification of G3V. It has a quiescent chromosphere and does not appear to be variable. The star has 18% more mass than the Sun and a 46% greater size. It is around 2.5 billion years old with a higher than solar metallicity, and is spinning with a projected rotational velocity of 3 km/s. The star is radiating 2.21 times the luminosity of the Sun from its photosphere at an effective temperature of 5.834 K.
A faint co-moving companion star, designated component B, was detected based on observations during 2003–2004, located to the south of the primary component. This corresponds to a projected separation of. The star is magnitude 10.62 A third companion, component C, was discovered in 2007, located about from component B. It has a visual magnitude of 15.6.
In 2002, the Anglo-Australian Planet Search team announced the discovery of an extrasolar planet orbiting the star. The discovery was independently confirmed by the Geneva Extrasolar Planet Search team.
