759 Vinifera (prov. designation: A913 QC or 1913 SJ) is a large background asteroid from the central regions of the asteroid belt, approximately 50 kilometers (31 miles) in diameter. It was discovered on 26 August 1913, by German astronomer Franz Kaiser at the Heidelberg-Königstuhl State Observatory in southwest Germany. The dark X-type asteroid has a rotation period of 14.2 hours and a heavily elongated shape. It was named after the plant species vitis vinifera, also known as the common grape vine.
