1020 Arcadia is an asteroid that was discovered by German astronomer Karl Wilhelm Reinmuth on March 7, 1924. Its provisional designation was 1924 QV. This object was named after Arcadia, a mythological Greek location and modern Greek province. Measurements of the lightcurve made in 2010 and 2011 give a rotation period of 17.02 ± 0.02 hours. It has a diameter of 25.9 km and a Tholen classification of S.
This object is a member of the Agnia family of asteroids that share similar orbital elements and physical properties. This family was named after the asteroid 847 Agnia. They most likely formed from the breakup of a basalt object, which in turn was spawned from a larger parent body that underwent igneous differentiation.
