Another Moon for Jupiter



Stephen P. Synnott of the Voyager Optical Navigation Team at the Jet Propulsion Laboratory in Pasadena has reported finding yet another moon of Jupiter—its 15th.

The new-found satellite, provisionally called 1979 J2, is estimated to be about 70 to 80 km in diameter and to have an orbit that places it between satellites Amalthea and Io, at a distance of about 151,000 km above the planet's clouds. The satellite circles the planet in 16 hours, 16 minutes.
