Finding 2 more moons around Jupiter

Scientists at the Carnegie Institute of Science say they have discovered two more moons flying around Jupiter, bringing the planet's total moon count to 69 individuals.

New moon

2 Moon names are S / 2016 J1 and S / 2017 respectively J1 , they are set according to the detection date in the sky. The term 'S' in satellite means satellite and the word 'J' in Jupiter means Jupiter.

Both satellites are said to have diameters of about 1 km and 1.2 km respectively. They fly around Jupiter with a distance of 21 million km and 24 million km. In addition, S / 2016 J1 also takes 1.65 years and S / 2017 J1 takes 2.01 years to complete 1 rotation.

In addition, they also have a high inclination of about 140 to 149 degrees (compared to the plane of the parent star). The two Moon's orbit is also very strange; when they fly fast and very close to the planet, sometimes fly slowly and far away.

Many moons yet to be found are turning around Jupiter

Scott Sheppard, the leader of the research team, said the above moons were first observed in the sky in March 2016 and March 2017 by the Subaru telescope in Mauna Kea, Hawaii.

While searching for signs of the ninth planet outside the Solar System, experts accidentally discovered images of these two planets appearing near Jupiter; It is possible that there are many more Moon like this nearby.

" At these observation campaigns, scientists have found most satellites orbiting the star. However, sometimes we can detect some new satellites and do Sheppard lost some other instances, ' Sheppard wrote on her blog.

" We may also inadvertently find more than two new satellites in our observations in 2017, but wait until re-observing in 2018, scientists dare to claim which one is new, what Any old and any ones lost the mark ".

These were also the first new satellites discovered around Jupiter since the last time in 2011. At that time, Sheppard and his team found two other moons of similar size.

All satellites larger than 100 km in diameter have been discovered when Voyager 1 passed by in 1979.

So with this new discovery, Jupiter definitely owns 2 outstanding titles. First, it is the planet with the most moons (69 individuals); and second, it is also the oldest planet in the Solar System.
