1064 Aethusa is a minor planet orbiting the Sun. Initially it received the designation 1926 PA.It was later named after a genus of plants Aethusa.[1]

It has a diameter of 17 km and has a high albedo.

Measurements made with the IRAS observatory give a diameter of 20.64 ± 1.37 km and a geometric albedo of 0.27 ± 0.03. By comparison, the MIPS photometer on the Spitzer Space Telescope gives a diameter of 8.621 ± 4.28 km and a geometric albedo of 0.17 ± 0.04.[2]

Photometric observations of this asteroid collected during 2006 show a rotation period of 8.621 ± 0.004 hours with a brightness variation of 0.18 ± 0.02 magnitude.[3]
