[ this star is too dim to be seen with the naked eye. It is close enough to the Earth that its distance can be determined using parallax measurements, yielding a value of roughly {{Convert|224|ly|pc|abbr=off|lk=on}}.[1]]This is a G-type main sequence star with a stellar classification of G6 V.[4] It has around 95% of the Sun's mass and is around 8.1[16] billion years old.
Planetary system
In October 2008 the planet HD 143361 b was reported to be orbiting this star. This object was detected using the radial velocity method during an astronomical survey conducted by the Magellan Planet Search Program using the MIKE echelle spectrograph on the 6.5-m Magellan II (Clay) telescope.[15]
