Two new Jovian moons confirmed

"Jupiter's tally of moons has gone up by two, after researchers
published their observations of two previously unknown Jovian
satellites.

The romantically-named S/2010 J 1 and S/2010 J 2 are both
tiny. The former is just three kilometres across. The latter is
even smaller, boasting a diameter of just two kilometres. That
small dimension is nonetheless noteworthy, as it means the
discovering scientists from the University of British Columbia
have claimed the crown for spotting the smallest moon so far
observed from Earth."
