其直径约为两公里，轨道平均半径为19,088 Mm，轨道周期为538.780地球日，与黄道间的轨道倾角为145°，运转方向为逆行，离心率为0.0960。

它于2003年正式以希腊女神欧波里亚（Euporie）命名，她是丰饶女神，同时是希腊神话中荷赖的一员（因此是宙斯的女儿）。

它是阿南刻群中的成员。

Euporie, also known as Jupiter XXXIV, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi 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 19.266 million km in 550.69 days, at an inclination of 145.7° to the ecliptic, in a retrograde direction and with an eccentricity of 0.148. It is affected by the Kozai mechanism.

It was named in August 2003 after Euporie, a Greek goddess of abundance and one of the Horae in Greek mythology (and thus a daughter of Zeus). It is a member of the Ananke group.
