Astronomers have discovered 11 additional moons orbiting the planet Jupiter. With
Revelations The number of known moons and holidays around Jupiter reached .39
The moons were first discovered in December by a team led by astronomers
David Jewitt and Scott Shepherd of the University of Hawaii, and their existence was confirmed
Now by Jewitt's team and other astronomers. The "Union
The International Astronomer officially confirmed the existence of the new moons.
Jupiter is now considered to be the planet with the largest number of moons in the system
the sun; It is followed by Saturn with thirty moons, and Uranus with twenty
moons
In an official statement issued by the University of Hawaii, Jewitt said that "their size
of the new moons is small compared to Jupiter's 'big four moons'
(Io, Europa, Ganymede and Callisto) discovered by Galileo in 1610 according to
The calculations made by the researchers, the diameter of the new moons varies between two
for four km.
The moons are defined as "unusual," Jewitt said, "because they are holidays
around Jupiter in an orbit opposite to the direction of its rotation, and their orbit an oval shape,
Unlike, for example, the moon's orbit around the earth. as far as we know,
Jupiter has 31 'unusual' moons today."
Researchers still don't know what the new moons are made of, but
They are thought to be rocky bodies, reminiscent of asteroids in composition.
The discovery of the moons was made through observations from the Canadian-French telescope in Hawaii
And one of the most powerful digital imaging cameras in the world. "The information he collected
The telescope is translated into digital information and quickly scanned by computers,"
Jewitt said.
The researchers speculate that Jupiter has many more moons, “maybe a hundred, maybe
More," Jewitt estimates. The team's research, he said, will now focus
In an attempt to understand how "Jupiter acquired such a strange collection of moons,
which may also help us in understanding the development of our solar system."
Scientists: The 17th moon around Jupiter has been discovered
25/07/2000
The discovered moon is the smallest: less than 5 km in diameter
by Tamara Traubman
Astronomers announced yesterday that they may have discovered an unknown moon around the holiday
Jupiter, the first moon of Jupiter to be discovered in about 20 years.
The researchers said that if their observations are confirmed, it would be the smallest moon
Among the 16 moons (already known) the holidays around Jupiter - its diameter is small
from five kilometers (compared to the 3,475 kilometers of the sphere's moon
Country).
At this point the small moon does not have a name, only the designation S/1999J1 and its diameter is calculated
for 4.5 km.
"It's exciting to realize that you are the first person to see something that no one has seen before,"
Jeff Larsen, a team member from the Spacewatch project, told reporters
University of Arizona, where they scan the solar system with the telescope
""Kitt Peak in search of comets and asteroids.
Larsen and his colleagues discovered the moon during observations conducted in October
and November last year, when Jupiter was at its closest point to Earth
in its 12-year orbit around the sun. The researchers said that before they gave
to the moon there, they want to make further observations to confirm the discovery.
Larsen noted that "this moon belongs to a group of moons moving in the outer part
of Jupiter, in a peculiar orbit, opposite to that of the inner moons of
justice".
Astronomers believe that the origin of this outer group of moons is
In asteroids captured by Jupiter's gravity, the planets are large
in the solar system.
Astronomers from the University of Arizona and Cambridge participated in the discovery.
in Massachusetts. At first they thought it was an asteroid, since the research is
An extensive project called Spacewatch (the sky scanner) intended for the site
Asteroids that may collide with Earth. But now "the mask has been removed"
Above the face of the mysterious sky gram and it turned out to be the moon that belongs to it
to the system of Jupiter's moons. This fact came up only now after it was clarified that the moon
A holiday around Jupiter and not around the sun.
