Hubble View of Comet Tempel 1 - After Outburst
The Comet was approximately 0.8AU (120 million km, 74 million miles) from Earth and approximately 1.5AU (224 million km, 139 million miles) from the Sun at the time of these exposures
The comet's nucleus is approximately 5-6 km (3-4 mi) in diameter. It is not resolved in the HST images. The image is 10 arcseconds wide, approximately 6100 km (3800 mi) at the distance to the comet.
The Hubble image was created from HST data from proposals 10144: P. Feldman (Johns Hopkins University), M. A'Hearn (University of Maryland), M. Belton (National Optical Astronomy Observatories), K. Meech (University of Hawaii), H. Weaver (Johns Hopkins University Applied Physics Laboratory).
