Jupiter's family of moons grows by two

The largest planet in our solar system is home to two of the smallest moons.  The discovery pushes the number of Jovian moons to 67.  Named S/2010 J 1 and S/2010 J 2, the two moons are only three and two kilometres in size respectively.

S/2010 J 1 (circled) measures three kilometres in diameter and takes two years to orbit the planet Jupiter.
