Comet Garradd, formally designated as C/2008 Q3, is a non-periodic comet that was observed from August 2008 to June 2010. It is the 11th out of 17 comets discovered by Australian astronomer, Gordon J. Garradd.
Physical characteristics Infrared and spectroscopic observations by the Herschel Space Telescope determined that while the comet was around from the Sun, its water production rate was measured at 1.7–2.8×1028/s−1. Data obtained by Akari detected a relatively high CO/ ratio for such a dynamically new comet, which may be caused by an outburst event prior to being observed by the satellite itself.
Its nucleus is estimated to have an effective diameter of , with a mass roughly about .
