867 Kovacia (prov. designation: A917 DH or 1917 BS) is an elongated, dark asteroid and member of the Hygiea family from the outer regions of the asteroid belt. It was discovered on 25 February 1917, by astronomer Johann Palisa at the Vienna Observatory in Austria.^[1] The carbonaceous C/B-type asteroid has a rotation period of 8.7 hours and measures approximately 24 kilometers (15 miles) in diameter. It was named after Austrian physician Friedrich Kovacs (1861–1931).^[2]
