Astronomers have found what are probably two new satellites of Uranus,
bringing the total to 20—the most known for any planet. The two are the
faintest satellites ever found by ground-based telescopes. Each one is about 20
kilometres in diameter, says J. J. Kavelaars of McMaster University in Hamilton,
Ontario, a member of the team that made the discovery. Both satellites have
irregular, continually changing orbits which do not lie in the plane of the
planet’s equator.
