Hubble View of Comet Tempel 1, Before Impact
About the Object
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.The comet was approximately 0.91AU (136 million km, 85 million miles) from Earth and approximately 1.51AU (224 million km, 139 million miles) from the Sun at the time of these exposures.
