64 Eridani is a single,

light years.[7] In addition to its proper motion, it is moving closer to the Sun with a radial velocity of around −9 km/s.[6]

This is an F-type main-sequence star with a stellar classification of F0 V.[4] It is catalogued a low amplitude Delta Scuti variable with a primary period of 0.273 days.[5] It was originally classified, tentatively, as an RR Lyrae variable of type 'c'.[13]

64 Eridani is spinning rapidly with a

Sun's luminosity from its photosphere at an effective temperature of roughly 7,346 K.[9]
