A new moon in Jupiter.                                                      

A small world of only two km in diameter might be the smallest moon known in Jupiter’s orbit.

 This tiny rock it was recently discovered together with another small moon in the enormous orbit.

The finding will be published in the magazine “Astronomical Journal”.

In September of 2010 two distant and until recently unknowns moons were detected bi an international scientific time during the routine follow up of the other known moons.

This objects were observed in various occasions, to determined whether they wear satellites of Jupiter or not  

 June of 2011, finally were awarded the designations S/2010 J 1 y S/2010 J 2.

The orbit’s determination for these satellites has been affirmed enough so that its position can be predicted reliably for several years in the future.

The researchers could estimate the size of the moons based on their brightness. Estimate that in diameter, while has only 2 Km. S/2010 J 2 is the weakest satellite Jovian discovered apt now. J 1 rotates about 20 millions of km that Jupiter, while J2 makes some 23 millions.

With these new incorporates, Jupiter have 67 Satellites well nouns.
