Astronomers have found three previously unknown moons in our solar system — two additional moons circling Neptune and one around Uranus. The latest tally puts Neptune at 16 known moons and Uranus at 28.
Astronomers have discovered 3 previously unknown moons in our solar system: 2 additional moons orbiting Neptune, and 1 orbiting Uranus. The latest statistics show that Neptune has 16 known satellites and Uranus has 28.
The distant tiny moons were spotted using powerful land-based telescopes in Hawaii and Chile, and announced Friday by the International Astronomical Union’s Minor Planet Center.

One of Neptune’s new moons has the longest known orbital journey yet. It takes around 27 years for the small outer moon to complete one lap around Neptune, the vast icy planet farthest from the sun, said Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington who helped make the discovery.
One of Neptune’s new moons has the longest known orbital journey to date. The discovery was facilitated by astronomer Scott Shepard of the Carnegie Institution for Science in Washington. He said that it took the small outer satellite about 27 years to complete one orbit around Neptune, the giant icy planet farthest from the sun.
The new moon orbiting Uranus, with an estimated diameter of just 5 miles (8 kilometers), is likely the smallest of the planet’s moons.
