 It is known as a weak-lined WNE star because of the high temperature but relatively weak emission strength.The physical parameters of WR 46 are all estimates from assumptions about the distance and models for stars of its type, complicated by the suspicion that there is a companion star.The effective temperature is over 110,000K, the luminosity greater than 200,000 times the solar luminosity (), the mass around 14 times that of the Sun () and a radius of 1.36 times the solar radius ().
