A bibliografic search for new mass determination of asteroids yielded two promising candidates, (10) Hygiea and (15) Eunomia. Ussing a close approach between the asteroids (15) Eunomia and (1284) Latvia of 0.014 AU at a relative velocity of 0.041 km/s in 1960, we determined a first value for the mass of (15) Eunomia. We obtained a value of (2.0 ± 0.4)x10-11 solar masses. Other close approach between the asteroids (15) Eunomia and (1313) Berna of 0.031 AU at a relative velocity of 0.022 km/s in 1955 gives a mass for Eunomia of (1.3 ± 0.7)x10-11 solar masses
