Abstract

A POSSIBLY NEW SATELLITE TO JUPITER.—A note in No. 4237 of the Astronomische Nachrichten (p. 207, March 6) announces the discovery of a new minor planet, or, possibly, a satellite, near Jupiter. The object was discovered by Mr. P. Melotte on a plate taken by him with the 30-inch equatorial reflector on January 27, and is of the sixteenth magnitude; it has been observed at Greenwich on seven nights since that date, and Prof. Wolf photographed it at Heidelberg on March 3. Should this faint object prove to be a minor planet, its temporary designation will be 1908 CJ, and it will probably prove to be a unique object, as regards its orbit, of its class. But it seems likely-so far as can be judged from the few observations yet made-that it is, really, an eighth member of Jupiter's satellite system, and if this is so it is probably the faintest and most distant yet discovered.
