Jupiter has 12 more moons, scientists found while looking for Planet X

Scientists announced the discovery of 12 new moons orbiting the planet Jupiter, including one that bucks the trend by orbiting in the opposite direction from others of its kind. The moon, tentatively named Valetudo, also has a more inclined orbit than other prograde moons and is one of the smallest moons of Jupiter discovered to date, measuring less than 1 kilometer in diameter.

The number of known objects orbiting Jupiter is now 79, the most of any planet in the solar system.

The discovery actually took place in the spring of 2017 but as Gareth Williams at the International Astronomical Union's Minor Planet Center points out, it takes several observations to confirm an object actually orbits Jupiter.

"We're looking for new possible planets and dwarf planets in our solar system, just seeing what is out there", Sheppard said.

"This is an unstable situation", said Scott S Sheppard, who helped lead the team that made the discovery of the 12 new moons. It's also likely Jupiter's smallest known moon, being less than one kilometer (0.6 miles) in diameter. Two of the newly discovered moons were found among these prograde moons, and take a little less than a year to go around in their orbit once. Near those nine is one moon that likes to move to the beat of its own and, like the two closer to Jupiter, has a rotation that mimics its host planet.

Astronomers have proposed the name "Valetudo" for the oddball moon, after the Roman god Jupiter s great-granddaughter, the goddess of health and hygiene. "Head-on collisions would quickly break apart and grind the objects down to dust."Some of Jupiter's moons and moon groupings, including the "oddball", could have formed from collisions like this, according to the statement".

The researchers believe the oddball may be a leftover fragment from a larger prograde moon that split apart from repeated collisions.

She believes that he has "demonstrated his quality working under Maurizio Sarri ", and that he will " help bring further success to Stamford Bridge ".

That seems to be what happened to astronomers working at the Cerro Tololo Inter-American Observatory in Chile, where a planned survey of trans-Neptunian objects was interrupted by Jupiter.

Telescopes in Chile, Hawaii and Arizona were used for the original discovery and year-long confirmation of the moons.

In fact, as technology continues to improve there is a chance even more moons could be found around Jupiter.

"Valetudo is like driving down the highway on the wrong side of the road".

All the newly identified moons are relatively small, ranging in size from about six-tenths of a 1km to 4km. They were also the first to realise that there just might be a massive planet out there in the outer reaches of the solar system. What's truly weird is that this set up prone to four moon-to-moon collisions. One possibility is NASA's Europa moon mission planned in the late 2020s or early 2030s.

This isn't likely to be the last new moons that we hear about coming from the gas giant, and astronomers believe there are still plenty of smaller satellites that remain undetected. These moons orbit in a clockwise direction, in the view above.
