Twelve new moons were discovered around Jupiter, bringing to 79 its total number of known satellites, a record among the planets of our solar system, announced an American team of astronomers. Researcher Scott Sheppard of the Carnegie Institution for Science has called one of these new moons a "strange ball" because of its small size: just under one kilometer in diameter, making it "probably The smallest satellite of Jupiter. Its orbit is also "different from that of all other known Jupiterian moons," said the astronomer. It takes about a year and a half for this "strange ball" to circle Jupiter, whose inclined orbit intersects those of a cloud of other moons moving in the opposite direction of the rotation of Jupiter. Astronomers have proposed to call "Valetudo" the "strange ball", named after the great-granddaughter of the Roman god Jupiter, goddess of health and hygiene.
