The new satellites bring Jupiter's tally to 47 compared with 30 for Saturn, the planet with the second most number of moons.

Jupiter's new satellites were discovered in early February 2003 by Scott Sheppard and David Jewitt of the University of Hawaii, US, working with Jan Kleyna of Cambridge University, UK.
They were found using the world's two largest digital cameras at the Subaru Telescope (8.3-metre diameter) and the Canada-France-Hawaii (3.6-metre diameter) telescopes on Mauna Kea in Hawaii.
The satellites were formally announced to the astronomical community on 4 March.
The new moons are all small; two to four kilometres in size, and orbit Jupiter at great distances from the planet.
Jupiter is now some way ahead of Saturn in the number of its moons
Two of the seven new satellites (S/2003 J1 and S/2003 J6) have an orbit around Jupiter that is in the same direction as Jupiter's spin).
The other five have distant so-called retrograde orbits like the majority of the known irregular satellites of Jupiter.
