Aoede is a very small moon of Jupiter’s, and is a member of the Pasiphae group. It’s also known as Jupiter XLI. It was discovered by a team of astronomers led by Scott S. Sheppard at the University of Hawaii in 2003. Very little is known about it.

5 Interesting Facts

1. Aoede is a member of the Pasiphae group, which orbits retrograde and at a highly inclined and eccentric orbit. Probably a captured asteroid.

2. Its original temporary designation was S/2003 J 7.

3. It’s pronounced ay-ee-dee.

4. Sheppard has been involved in the discovery of 75 moons. Okay, so this isn’t about Aoede.

5. Really, there’s very little known about Aoede. I can’t do five interesting facts.

With such a highly inclined and eccentric orbit, and such a small size, it’s unlikely we’ll see any kind of exploration of this moon any time soon.
