The system is traversing the celestial sphere with a relative proper motion of 24.9 mas/y, and is moving away from the Earth with a heliocentric radial velocity of +5.8 km/s. The dual nature of this system was discovered by W. Herschel in 1783, when they showed an angular separation of 9.8\u2033. As of 2015, the two components of this system had a separation of 9.60\u2033 along a position angle of 210\u00B0. This is equivalent to a projected separation of 241.3 AU; wide enough that, thus far, their orbital track appears linear. They are nearly identical F-type main-sequence stars with a stellar classification of F8V. The primary is slightly brighter at magnitude 5.64, while the secondary is magnitude 5.76."@en . "4.17"^^ .
