Moons of Jupiter

Moons of Jupiter 

Jupiter has a total of 79 known moons, which are divided into several groups based on their orbital properties. The four largest moons of Jupiter, known as the Galilean moons, are Io, Europa, Ganymede, and Callisto. These moons were first observed by Galileo Galilei in 1610 and are among the most studied objects in the solar system.

There are some Jupiter moons which we discuss: 

1. Elara
2. Dia 
3. Erinome 
4. Eirene 
5. Ersa

• Dia: 

The Himalia group, which includes Dia, is a group of irregular satellites that orbit Jupiter at a distance of 11-13 million kilometers. These moons have prograde orbits, meaning that they orbit in the same direction as Jupiter's rotation. The group is named after its largest member, Himalia. It is located at a distance of 12 million km from Jupiter and completes one cycle in 274 days. It was discovered by Scott S. Sheppard in 2000.  

• Erene: 

Eirene, also known as Jupiter XLV, is a retrograde irregular satellite of Jupiter. It was discovered in 2003 by Scott S. Sheppard and its orbit is highly inclined and elliptical. Eirene's size is estimated to be around 2 kilometers in diameter.

• Elara: 

Elara, another member of the Himalia group, is the eighth largest moon of Jupiter and was discovered by Charles Dillon Perrine in 1905. Elara has a diameter of about 86 kilometers and orbits Jupiter at a distance of 11.7 million kilometers.  Its distance from Jupiter is 11.7 million km and it completes one revolution in 258 days.  Discovered by D. Perrine and passed by the New Horizons spacecraft in March 2007. 

•  Erinome: 

Erinome, also known as Jupiter XXVIII, is a small irregular moon of Jupiter that was discovered in 2003 by David C. Jewitt. It has a diameter of about 3 kilometers and orbits Jupiter at a distance of approximately 22 million kilometers. It completes one cycle in 711 days. It was discovered by David C. Jewitt in May 2003. 

• Ersa: 

Ersa, the most recently discovered moon on this list, was discovered in 2018 by Scott S. Sheppard. It is about 3 kilometers in diameter and orbits Jupiter at a distance of approximately 11 million kilometers.. It completes one cycle in 252 days. It was discovered by Scott S. Sheppard in May 2018.

Jupiter's moons provide scientists with valuable information about the formation and evolution of the Jovian system, and ongoing missions such as the Juno spacecraft continue to study these intriguing objects in more detail.
