The two stars share a [[common proper motion]] and lie about 340 light years away.

The primary star is an [[A-type main-sequence star]] with a spectral class of A2V and an [[apparent magnitude]] of 6.1, just visible to the [[naked eye]] om ideal conditions. The 10th-magnitude companion lies at an [[angular separation]] of 4.6[[arc second|″]] along a [[position angle]] of 110° (as of 2010).<ref name=WDSC2014/>

The A-type star is over twice as massive as the [[Sun]] and over 40 times as [[bolometric luminosity|luminous]]. It has an [[effective temperature]] of {{val|fmt=commas|9,434|ul=K}}.<ref name=dr3a/> The fainter secondary has only 80% of the [[Sun's mass]] and 40% of [[solar luminosity|its luminosity]] and its photosphere is at a temperature of {{val|fmt=commas|5,099|u=K}}.<ref name=dr3b/>
