Authors


Abstract

With the International Astronomical Union's formal announcement on 16 May of 11 newly-discovered moons orbiting Jupiter, the number of known moons around that planet now totals 39. This is the largest number orbiting any planet in the solar system, and nine more

Each of the newly-found Jovian moons measures 2 to 4 kilometers in diameter, and they are irregular satellites with large, elongated, and inclined orbits.
