Paulo Renato Centeno Holvorcem (born 10 July 1967) is a Brazilian amateur astronomer and mathematician who lives in Brasilia, Brazil.
He is a prolific discoverer of asteroids. He is credited by the Minor Planet Center with the discovery or co-discovery (with Charles W. Juels) of about 197 minor planets between 1998 and 2010.
Holvorcem with Juels also discovered two comets: C/2002 Y1 (Juels-Holvorcem) and C/2005 N1 (Juels-Holvorcem). Holvorcem was also involved in the discovery of C/2011 K1 (Schwartz-Holvorcem).
The main-belt asteroid 13421 Holvorcem was named after him on 9 January 2001 .
Paulo's SkySift[1] pipeline software is used by many observatories across the world for the detection of minor planets and transients.
