Astronomers have found ten new Jupiter moon and an Oddball
Astronomers discovered 10 more moons of Jupiter, bringing to 79 the number known to circle the massive gas planet, including one “Odd-ball” that seems bound to collide with different moons sharing its orbital expressway.
All the recently discovered moons are smaller in size. While Jupiter, the fifth planet from the Sun, has substantial moons, for example, Ganymede – the greatest in the close planetary system with a breadth of 3,273 miles (5,268 km) – the new ones territory in measure from around six-tenths of a mile (1 km) to 2.5 miles (4 km) – is little contrasted with whole diameter of Jupiter 88,846 miles (142,984 km).
Space researchers of Carnegie Institution for Science in Washington led by Scott Sheppard have discovered 12 smaller Jovian moons, including the ten announced. Sheppard said these moons were most likely formed closer to Jupiter at the beginning of solar system and were “captured” by the planet’s solid gravitational force.
Jupiter is like vacuum cleaner since it’s so huge,” Sheppard said. “These objects started orbiting Jupiter, instead of falling into it. So we think they’re intermediate between rocky asteroids and icy comets. So they’re probably half ice and half rock.”
The most intriguing of the new moons is Valetudo (val-eh-TOO-doh), named after the Roman god Jupiter’s granddaughter, the goddess of wellbeing and cleanliness. Valetudo orbits Jupiter in the same direction, whereas a smaller group of other moons share the same orbital way while orbiting opposite ways.
“Valetudo’s going down the highway the wrong way, so it’s very likely it will collide with these other objects. It probably has collided with them over time,” Sheppard said.
Jupiter’s 79 known moons are most of any planet in the planetary system, trailed by the 62 found orbiting around planet Saturn. Jupiter and Saturn may actually have a similar number of moons, with some of Saturn’s smaller ones not yet detected, said Sheppard.
