Astronomers announced the rediscovery of 10 new Jupiter satellites, bringing the total number of Jupiter to 79.
Jupiter is the largest planet in the solar system If you look at the night sky from Earth, Jupiter is the third most brilliant object after the Moon and Venus. Until now, astronomers have sent several unmanned spaceships to explore Jupiter, from the first Spacecraft Pioneer 10 (Pioneer 10 or Pioneer F) to Jupiter, the first navigators of Jupiter browsers 1 and 2, to the late Galilee.
The spacecraft that recently visited Jupiter has a new horizon number that hangs at Pluto (the closest to Jupiter on February 28, 2007 and accelerated to Jupiter with the gravity of Jupiter), and the Juno is currently the only one on Jupiter's orbit. Detectors in service, there are still many space missions in the future to prepare for the detection of the Jupiter system, such as the detection of the Europa Europa flight mission of the Jupiter satellite.
Jupiter has the largest number of satellites in the solar system, with a total of 69 previously known, two of which are astronomers from the Carnegie Institution for Science, who discovered a new batch of satellites. The team that Scott Sheppard's team has announced for the first time in June 2017 has announced 10 more on July 16, 2018.
But the original research goal of the team is to have the team. Scott Sheppard's team was not the Jupiter satellite, but the legendary ninth planet in the solar system (Planet X), large enough to rearrange small celestial bodies on the edge of the solar system. Follow
In March 2017, when they used the 4-meter Blanco telescope at the Inter-American Observatory of Cerro Tololo (CTIO) in Chile, they observed outside of Pluto. When the solar system is at the edge of the object, it is not expected that Jupiter enters the field of view of the telescope because of the edge, and there are several new objects that were previously unknown.
They are very small, about 1 to 4 kilometers in diameter, after about a year of tracking the orbit of the object, the team finally confirmed that it was 12 new satellites orbiting Jupiter.

These new satellites all belong to the peripheral satellites of Jupiter (10 to 20 million kilometers from Jupiter, tens of times more than the distance from the Earth to the Moon), Three have the same prograde orbit as the Earth's moon, and nine have a retrograde orbit, which can be subdivided into three categories based on orbital characteristics, said Scottrade: they may have been large. Part of the satellite has been split for some reason, and astronomers are currently doing computer simulations to determine how the old satellites created this situation.
The most special thing is that a new member is treated as a "monster" and the team called it "Valetudo" (formerly known as MMA). Although it has an orbital orbit, it is snuggled near the retrograde orbit satellite, described by Scott Cork, as a lost vehicle traveling backwards in a highway car. Valetudo revolves around Jupiter 18 months per week, in astronomy. The family believes that she will face other satellites in the future.
The team is ready to solve this question: Where does Valetudo come from? How does he enter the field of retrograde satellites? As telescope technology continues to improve, Scott Scuba expects us to find more Jupiter satellites that will help scientists to reveal the story of Jupiter's formation and the future. other gaseous giant planets and discover the mystery of retrograde satellites. The team believes that the retrograde satellite may be just a pbader by at first, but it is captured by the gravity of Jupiter and earns income.
Note: Astronomer Scott Sheppard has discovered many moons of Jupiter, Saturn, Uranus and Neptune, as well as a 2004 UP10 Neptune Troy, a 2008 LC18 and some celestial asteroids Cooper. Discoverers with objects close to the Earth.
