Comet 8P/Tuttle on 10 December 2007, in an image by Peter Lawrence of Selsey, West Sussex, UK. He writes: "Here are two images of two very different comets combined at the same scale to illustrate just how massive Comet Holmes now looks compared to another periodic comet, 8P/Tuttle, which is set to brighten as we pass into January 2008."
