Previously unknown moons in the solar system were discovered by telescopes in Hawaii and Chile.
Accordingly, astronomers have revealed that in addition to the 2 moons orbiting Neptune, there is also a small satellite around Uranus.
The International Astronomical Union announced that with the new discoveries, the number of Neptune's moons has increased to 16 and Uranus to 28.
Astronomer Scott Sheppard of the Carnegie Institution for Science in Washington, D.C., said the small satellite takes about 27 years to circle Neptune, the farthest icy planet from the Sun.
Sheppard also said that there may be many small satellites that have not yet been discovered.
The new satellite orbiting Uranus, with an estimated diameter of 8 kilometers, is likely to be the smallest of the planet's moons.
