On 1973 November 23, there was a close approach (0.013AU) between (704) Interamnia as the fifth largest minor planet, and (993) Moultona. It was made an attempt to determine the mass of Interamnia from its perturbations on the motion of Moultona, using 82 right ascensions, 72 declinations, and of 1 observation the portion normal to the apparent motion, from altogether 95 observations from 22 oppositions 1923 January to 1991 February with a mean error of 0.″51. For the mass of Interamnia was obtained a result of 0.37 ± 0.17 · 10-10 solar masses. Although its uncertainty, this result gives an independent information about the mass of Interamnia besides the estimation from the diameter and the suspected density, considering the uncertainty of these parameters.
