AB Pic and Its Imaged Companion
AB Pic is a K0 star 163 light-years away, with measurements placing its age at a reported upper limit of 1 billion years, its mass at 0.9 solar masses, its radius at 0.73 solar radii, and its temperature at 5380 K. The star's reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.
That planet, AB Pic b, was discovered by imaging in 2005. Its reported mass estimate is 4290 Earth masses, larger than Earth's and roughly 13.5 times Jupiter's mass. No orbital period is reported for AB Pic b.
