The planets Neptune and Uranus grow: A research team has discovered three new moons, some of which orbit the planets at very large distances.

Washington, D.C. – This being So big that the search continues there Unknown celestial bodies or Previously unexpected phenomena Discover. Even in our country Solar System New discoveries are still being made, as the current example shows: a research team led by Scott Sheppard (Carnegie Center for Science) has discovered three new moons in the solar system. Two of the moons orbit Neptune, and a third, newly discovered moon orbits Uranus.

The moons, whose discovery was published by the Minor Planet Center of the International Astronomical Union (IAU), are small and inconspicuous. “The three newly discovered moons are the faintest ever detected by ground-based telescopes around these two icy giant planets,” co-discoverer Sheppard explains in an article. notice. “It required special image processing to detect these faint objects.”

In this image from the James Webb Space Telescope you can see the gas giant Neptune (below) in infrared light.  It's easy to see: its rings and clouds of methane ice (bright spots on the planet).  Seven of Neptune's fourteen known moons can also be seen.

The planets Uranus and Neptune have a total of three new moons

If you count the new moon called S/2023 U1, ice giant Uranus now has 28 natural satellites. The diameter of the newly discovered celestial body is eight kilometers, and it takes 680 days to orbit around its planet once. Like other moons of Uranus, S/2023 U1 will be named after a Shakespearean character.

With this discovery, Neptune, the outer planet in our solar system, now has 16 moons orbiting it. Neptune's brightest moon has been provisionally named S/2002 N5. It has a diameter of 23 kilometers and takes about nine years to orbit Neptune. Neptune's weakest moon (S/2021 N1) is 14 kilometers across and takes a full 27 years to orbit its planet once. Like all of Neptune's other moons, the two new discoveries are said to have names from Greek mythology. Previous moons were named after sea gods and nymphs.

Uranus and Neptune captured the moons through their gravity

The three newly discovered moons around Uranus and Neptune have distant, eccentric, and tilted orbits. According to experts, this indicates that they were captured by planetary gravity during or shortly after planet formation. A better understanding of how planets capture their moons could help astronomers learn more about the early years of our solar system and the motion of exoplanets.

It has the largest number of moons in our solar system Saturn has 145 known moons. Jupiter follows in second place With 92 confirmed moons. (unpaid bill)
