136 Austria is a main-belt asteroid that was found by the prolific asteroid discoverer Johann Palisa on March 18, 1874, from the Austrian Naval Observatory in Pola, Istria. It was his first asteroid discovery and was given the Latin name of his homeland. Based upon its spectrum, it is classified as an M-type spectrum, although Clark et al. (1994) suggest it may be more like an S-type asteroid. It shows almost no absorption features in the near infrared, which may indicate an iron or enstatite chondrite surface composition. A weak hydration feature was detected in 2006.
