Lysithea

Lysithea, formerly known as Jupiter X, is an outer irregular satellite of Jupiter that is within the Himalia Group. It’s the 13th largest moon of Jupiter, and 3rd largest in the Himalia Group. Very little is known about Lysithea, primarily due to a lack of interest.
==Discovery==
Lysithea was initially discovered when astronomer Seth B. Nicholson found it using the 100-inch telescope at the Mount Wilson Observatory. It was found on July 6, 1938.
==Appearance & Size==
It’s not known what Lysithea exactly looks like, as all images of it do not show any details of its surface. However, it’s assumably a small object with a similar appearance to other objects in the Himalia Group. Like other objects in its group, it’s thought that it originated from an asteroid that was torn apart and captured by Jupiter’s gravity or vice versa.
Lysithea has a diameter of about 22.37 miles, making it the 3rd largest object in the Himalia group, and the 13th largest overall.
==Orbit==
Similarly to other Himalia Group members, it has a slightly tilted and eccentric orbit. It orbits at 7.2 million miles away from Jupiter, and takes nearly 258.6 days to complete one orbit. This makes it the 15th closest moon to Jupiter.
