(341843) 2008 EV5 (or 2008 EV5) is a near-Earth, potentially hazardous, Aten asteroid. It was discovered by the Mount Lemmon Survey in Tucson, Arizona, United States, on March 4, 2008.

2008 EV5 is an oblate spheroid 400 m (1,300 ft) in diameter. It rotates in a retrograde direction.[1] There is a 150 m (490 ft) diameter concave feature, possibly an impact crater, or a relict feature from a previous episode of rapid rotation that caused the asteorid's shape to reconfigure.[1] Visible and near-infrared spectroscopy show that 2008 EV5's composition is similar to that of carbonaceous chondrite meteorites.[2] 2008 EV5 is listed in the JPL Small-Body Database and classified as: Aten NEO, PHA (SPK-ID: 2341843).[3]

2008 EV5 is the preliminary baseline target of a sample-return NASA mission.[4][5] Besides the asteroid 2008 EV5, several other space rocks, including Itokawa and Bennu, are being considered for this mission.[4][5]
