C/2006 W3 (Christensen) is a non-periodic comet that was observed through telescopes between 2006 and 2011. It is one of several comets discovered by American astronomer, Eric J. Christensen.
Physical characteristics Infrared observations from Herschel and Spitzer in 2009 allowed astronomers to estimate the size and rotation of C/2003 W3's nucleus. Initial estimates in 2010 revealed an effective radius of <, however this value was later revised to km in 2016, assuming a geometric albedo of 0.04. Data from Spitzer also revealed that the comet has a rotation period of 21 hours.
