Astronomers from the University of Carnegie discover 12 new satellites of the gaseous giant Jupiter
The study is published on the site of the institute
Thus, the total number of bodies Celestial known in the cloud of the largest planet in the solar system rose to 79.
A team of scholars led by Scott C. Sheppard of Carnegie spotted satellites for the first time in the spring of 2017 when they were looking for objects far removed from the solar system as part of a "hunt" for a supposedly massive planet Luton, often called the "ninth planet."
The presence of a large celestial body indicates the unusual behavior of objects in the far outlines of the solar system, moving as if they had a powerful gravitational influence.
"Jupiter was right in the field of vision where we were looking for objects extremely remote from the solar system, so we were able to discover new satellites around Jupiter and at the same time we were looking for a planet at the edge of our system
Gareth Williams of the Center for Small Planets of Mi The International Astronomical Union used the observation team to calculate the orbits of newly discovered satellites. [19659003
"Several observations are needed to confirm that the object is actually revolving around Jupiter," Williams said. "The whole process took a year."
All Open satellites are small and detected in the spring of 2017 with the help of a 4-meter telescope christened Victor Blanco in Chile.
Nine satellites to the outer group of satellites of Jupiter, and go around the planet in retrograde orbit in about two years. The other two are at a less distance from the celestial body and turn with it in one direction. One of the satellites received the name "Valetudo" – its diameter is less than one kilometer, the object is the smallest known satellites of Jupiter.
There is a high risk that Valetudo collides with another celestial body. Sheppard compares this satellite with a car traveling in the opposite lane
"This shows just how chaotic our solar system was in the past These outer Jupiter satellites are the remains of chaos, the reason these objects are "Just open, lies in the fact that over the last ten years, telescope technology has improved dramatically," Sheppard said.
