Radar Observations of Near-earth
Much useful information about physical and dynamical properties can be obtained from radar observations of near-Earth asteroids (NEAs) that come within reach of 1 Resolution of echoes in Doppler frequency and/or time groundbased radar telescopes . delay can be used to synthesize 1-D or 2-D images that show a target’s size, shape and rotation. Disc-integrated measurements also have value, becaus...
متن کاملRadar observations of Comet 2P/Encke during the 2003 apparition
The nucleus of Comet 2P/Encke was detected with the Arecibo radar during the close approach of November, 2003, making this the first comet to yield radar detections at two different apparitions. Although the measured radar cross section of 1.0 km2 was close to that obtained in 1980, the Doppler bandwidth was nearly four times larger. Most of this bandwidth difference can simply be attributed to...
متن کاملRadar imaging of binary near-Earth asteroid (66391) 1999 KW4.
High-resolution radar images reveal near-Earth asteroid (66391) 1999 KW4 to be a binary system. The approximately 1.5-kilometer-diameter primary (Alpha) is an unconsolidated gravitational aggregate with a spin period approximately 2.8 hours, bulk density approximately 2 grams per cubic centimeter, porosity approximately 50%, and an oblate shape dominated by an equatorial ridge at the object's p...
متن کاملPhysical characterisation of near-Earth asteroid (1620) Geographos: reconciling radar and thermal-infrared observations
Context. The Yarkovsky (orbital drift) and YORP (spin state change) effects play important roles in the dynamical and physical evolution of asteroids. Thermophysical modelling of these observed effects, and of thermal-infrared observations, allows a detailed physical characterisation of an individual asteroid to be performed. Aims. We perform a detailed physical characterisation of near-Earth a...
متن کاملSearch for Activity in 3200 Phaethon
We present deep optical imaging of Geminid meteor stream parent 3200 Phaethon taken in search of low-level cometary activity (i.e., coma or dust trail). Although no unambiguous cometary behavior was observed, we find an upper limit on the object’s cometary mass-loss rate of Ṁlim 0:01 kg s . The corresponding active fraction (the fraction of the surface area that could consist of freely sublimat...
