Two new Jovian moons confirmed
'S/2010 J 2' is smallest moon ever spotted from Earth
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.
The moons were first spotted in 2003, but are so small it's taken a while to make sure they have properly moon-like orbits, rather than being cosmic freeloaders. The recent publication of a paper, Discovery of two additional Jovian irregulars, means all the necessary i's have been dotted and all the tees crossed to officially add the pair to the now 67-strong list of Jupiter's moons.
On the off-chance you'd like to visit, S/2010 J 1 can be found a mere 23.45 million kilometres from the gas giant, while its smaller cousin is a little nearer at 21.01 million kilometres. ®

Re: "21.01 million kilometres"
The linguini in my cupboard is 10" long, when cooked it is longer so all we need to do now is clear up how well you like it cooked.
Actually my home made can be up to 6' long damp as it comes out of the machine so that can be cut to 20cm which is a good size and about 40% less shirt spray than the dried stuff if eaten properly.
That eventually leads to 2.101billion* anti-pastis, or the same number of main courses in a posh restaurant where the course is indicated by the plate size not the portion size.
*That's 10**9 or girly** billions as opposed to 10**12 for british journals prior to lots of bad engineering.
**girly is a non sexist term referring to the diminutive - though this does not apply in the US or cafes.
just to get rid of the lame, obvious joke, let me be the first who says "that's no moon..."
(blame this lame comment on the lack of sleep)
