In 1991 he was honored by the International Astronomical Union with the designation of Minor Planet 4435 Sykes for his discoveries and in 2007 he was the first recipient of the NASA Planetary Science Division Distinguished Service Award. In 2016 he was given the Harold Masursky Award for Meritorious Service to Planetary Science by the Division for Planetary Sciences of the American Astronomical Society.
