1947 Iso-Heikkilä, provisional designation 1935 EA, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 29 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory on 4 March 1935.[7]
The C-type asteroid orbits the Sun at a distance of 3.0–3.3 AU once every 5.60 years (2,046 days). It has a rotation period of 5.016 hours.[6] It has an albedo of 0.06, according to the Light Curve Database project.[3]
It is named for the farm, located in the Iso-Heikkilä district and owned by Turku University. It became the site of the Turku Observatory, which is also called Iso-Heikkilä Observatory, in Finnish: Iso-Heikkilän tähtitorni. The discovery of minor planet 1947 Iso-Heikkilä in 1935 was the first one made by the observatory.[2]
