A team of US astronomers announced the discovery of 12 new satellites around Jupiter, bringing to 79 the number of known moons, a record number in the solar system.
The researcher Scott Shepard of the Carnegie Institution for Science, one of these satellites described as a bit strange because of its small size, the diameter of less than one kilometer, which is probably the most small satellites of Jupiter.
The astronomer explains that his rotation is "different from other known satellites of the buyer". This moon needs a year and a half to revolve around the Jupiter, whose curve orbit meets a constellation of other satellites that rotate in the opposite direction of Jupiter.
"It's an unstable situation," said Shepard, "and face-to-face accidents can lead to the disintegration of satellites and their transformation into dust."
The Moon is like two other satellites recently discovered in the same sense as Jupiter. Nearby satellites need about a year to circulate around the planet, versus two years for more distant satellites. All of these satellites can be part of a collision between larger objects.
The Italian astronomer Galileo discovered in 1610 the first satellites of Jupiter.
The team of astronomers behind the discovery was not looking for new satellites for the buyer, but they appeared in the telescope field that they were using when they were trying to detect planets beyond Pluto.
The new satellites were spotted for the first time in 2017 by a telescope stationed in Chile and working for the US National Astronomical Observatory.
and asked for verification of how these satellites run for a full year using telescopes in the United States and Chile.
