New Moon
2 Jupiter's new moons are named S / 2016 J1 and S / 2017 respectively J1. According to scientists from the Carnegie Institute of Science, those who discovered these two new moons, they are placed according to the date of detection in the sky. Jupiter's "J" means Jupiter and the "S" in satellite means satellite.
Both of these new Moon fly around Jupiter at a distance of 21 million km, 24 million km and have diameters of about 1 km and 1.2 km respectively.
In addition, S / 2016 J1 needs 1.65 years and S / 2017 J1 needs 2.01 years to complete 1 rotation.
Especially, S / 2016 J1 and S / 2017 J1 has a high inclination of about 140 to 149 degrees (compared to the parent star's plane). According to astronomers observations, the trajectories of these two moons are also very strange, they fly fast and very close to the planet but sometimes fly slowly and far away.
Jupiter also has many moons orbiting it that we have not yet discovered
For the first time, scientists observed these moons in the sky respectively in March 2016 and March 2017. At that time, they were looking for signs of the 9th planet outside the Solar System with the Subaru telescope in Mauna Kea, Hawaii, when they accidentally saw images of these two planets appearing near Jupiter.
Jupiter is the largest planet of the Solar System and there are 53 officially named Moon and more than a dozen Moon waiting to be recognized by the International Astronomical Association. According to astronomers, there is a possibility that there are many Moon like this nearby.

With this new discovery, Jupiter becomes the most moon-shaped planet (69 individuals) and is the oldest planet in the Solar System.
