Harold Anthony "Hal" Weaver, Jr. (born 1953) is an American astronomer, known for his research into the composition of solar system bodies including comets and Kuiper belt objects.
His involvement in the New Horizons mission to Pluto and beyond meant that Weaver was also co-discoverer of Kerberos and Styx in 2011 and 2012 respectively. Weaver has frequently appeared with New Horizons principal investigator Alan Stern at press briefings announcing the mission's findings following the fly-bys of Pluto and 486958 Arrokoth, and has made media appearances to discuss the mission.[4]
