WASP-41 is a G-type main-sequence star. Its surface temperature is 5450±150 K. WASP-41 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of −0.080±0.090,[4] but is much younger at an age of 2.289±0.077 billion years.[6] The star does exhibit strong starspot activity, with spots covering 3% of the stellar surface.[5]

Multiplicity surveys did not detect any stellar companions as of 2017.[8]
