777 Gutemberga (prov. designation: A914 BF or 1914 TZ) is a dark and large background asteroid, approximately 66 kilometers (41 miles) in diameter, from the outer regions of the asteroid belt. It was discovered by German astronomer Franz Kaiser at the Heidelberg-Königstuhl State Observatory on 24 January 1914.[1] The carbonaceous C-type asteroid (Cb) has a rotation period of 12.8 hours. It was named after Johannes Gutenberg (ca. 1400–1468), who introduced the printing press to Europe and started the Printing Revolution.[2]
