    Solution

    Astronomers have discovered three previously unknown moons around Uranus and Neptune, the most distant planets in our solar system. The find includes one moon spotted orbiting Uranus — the first discovery of its kind in more than 20 years — and two detected in Neptune’s orbit. The three newly discovered moons are the faintest ever found around these two ice giant planets using ground-based telescopes. The revelations will be helpful for missions that may be planned to explore Uranus and Neptune more closely in the future, a priority for astronomers since the ice planets were only observed in detail with Voyager 2 in the 1980s. The three moons were announced on February 23 by the International Astronomical Union’s Minor Planet Center.
