Euporie (// ew-PORR-ə-ee or // ew-POHR-ee; Greek: Ευπορία), also known as Jupiter XXXIV, 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 2001, and given the temporary designation S/2001 J 10.
Euporie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 19,088 Mm in 538.780 days, at an inclination of 145° to the ecliptic (145° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.0960.
It is the innermost member of the Ananke group, retrograde irregular moons that orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
