An insider's look at the science of near-Earth comets and asteroidsOf all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objec

International audience; Many advancements in planetary science are achieved by seizing upon the opportunity created by rare natural events (e.g. comet Shoemaker-Levy 9 Jupiter impact; 1994) and by planned physical interactions (e.g. Deep Impact into

Comet 85P/Boethin was selected as the original comet target for the Deep Impact extended mission, EPOXI . Because this comet had been only observed at two apparitions in 1975 and 1986 and consequently had a large ephemeris error, an early intense rec

We present observational data for two long-period and three dynamically new comets observed at heliocentric distances between 5.8 to 14.0 AU. All of the comets exhibited activity beyond the distance at which water ice sublimation can be significant.

Deep Impact collided with comet Tempel 1, excavating a crater controlled by gravity. The comet's outer layer is composed of 1- to 100-micrometer fine particles with negligible strength (1000 kelvins). A large increase in organic material occurred dur

When compared to the discovered set of near-Earth asteroids, the Earth impact flux of all known active comets, including Jupiter family comets, Halley-type and long period comets, is below 1%. However, the comet impact fluxes may be higher for those
