The chance find brings the gas giant's tally of moons to 79 - 17 more than Saturn, the planet with the second most orbiting moons in the solar system.
Being less than 1km in diameter, this moon is more distant and more inclined than those found orbiting in the same direction as Jupiter's rotation (prograde) and would also likely be the planet's smallest. These distant retrograde moons are grouped into at least three distinct orbital groupings and are thought to be the remnants of three once-larger parent bodies that broke apart during collisions with asteroids, comets, or other moons.
Astronomers Just Announced The Discovery of 12 New Moons Around Jupiter
It also "has an orbit like no other known Jovian moon" and is "likely Jupiter's smallest known moon", he added. One moon detected by Sheppard and his colleagues is the smallest Jovian moon ever discovered.
The newly discovered Jupiter moons, with diameters of one to three kilometres (0.62 to 1.9 miles), required multiple observations to verify. That is, it is moving prograde while all the other objects at a similar distance from Jupiter are moving retrograde. "We could kill two birds with one stone: survey for Jupiter moons and very distant objects at the same time". "So that's why we're able to find these new moons".
A moon is defined as any object, regardless of size, that orbits a planet, not the Sun.
Astronomers are still finding moons at Jupiter, 400 years after Galileo used his spyglass to spot the first ones.
Klopp hands Sturridge a lifeline on Liverpool future
Jürgen Klopp has insisted that Daniel Sturridge still has a future at Liverpool despite consistent links of a move away this summer.
Jupiter's moons are arranged in a specific pattern that the giant planet has worked out over time. Which direction the moons swing around the planet depends on how they were first captured by Jupiter's gravitational field.
In March 2017, Jupiter was in the ideal location to be observed using the Blanco telescope at the Cerro Tololo Inter-American Observatory in Chile, which has the Dark Energy Camera and can survey the sky for faint objects.
A team of astronomers looking for a proposed planet past the orbit of Pluto got a surprise of their own when they discovered new moons around Jupiter.
Croatia greeted by 500,000 fans in return home after World Cup
During the award ceremony, Macron raised two victorious fists next to host president Vladimir Putin. But, despite the convincing French victory, there is little feeling of disappointment in Croatia .
If the "oddball" guy - set to be named Valetudo after the great-granddaughter of Roman god Jupiter - continues in its destructive ways and has more collisions, scientists think it may even destroy itself. "So, the whole process took a year", Dr. Williams said. "They also are fragments of the early solar system before the planets were formed, which makes studying them important to learning about the solar system's history". The telescope recently was upgraded with the Dark Energy Camera, making it a powerful tool for surveying the night sky for faint objects.
If they had formed earlier, the influence of gas and dust would have created drag and caused them to spiral inward to the planet, lost forever.
