S/2003 J 4

S/2003 J 4 is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003.
S/2003 J 4 is about 2 km in diameter, and orbits Jupiter at an average distance of 23,571 Mm in 739.294 days, at an inclination of 147° to the ecliptic (149° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.3003.
It belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 Gm, and with inclinations ranging between 144.5° and 158.3°.
This moon has not been seen since its discovery in 2003 and is currently considered lost. Follow-up observations in 2018 are planned to secure its orbit.

In Space Travel a ship is tested by travelling to and landing on various planets and moons within the Solar System. Jupiter was one such planet used in the testing process so it is probable that some of its moons were used as well.
