C/1652 Y1 was a naked-eye comet observed, among others, by Jan van Riebeeck. It was first spotted on 14 December 1652, in Mexico City, by Novohispano friar Diego Rodríguez, and next sighted on 16 December 1652, by Dutch observers at Pernambuco (Brazil). As of June 2008 the comet was about 280 AU from the Sun (very approximate due to poorly determined orbit).
