WASP-45 is a K-type main-sequence star about away. The star's age cannot be well constrained, but it is probably older than the Sun. Yet WASP-45 is enriched in heavy elements compared to the Sun, having 240% of the solar abundance. WASP-45 has low ultraviolet emission, therefore it is suspected to have a low starspot activity, although chromospheric activity was reported elsewhere.

There is a companion star at a separation of 4.4 arcseconds, corresponding to 929 AU. The companion is estimated to have a mass of and a temperature of . Although it shares a similar distance and common proper motion with the primary star, its relative space velocity appears to be high enough that the pair are not gravitationally bound.
