This site provides information related to the recently discovered asteroid 1997XF11 and how close it will come to Earth in 30 years. The Harvard-Smithsonian Center for Astrophysics provides a hyperlinked press release about 1997XF11, discovered by Professor James Scotti of the University of Arizona. The first estimates were as close as 30,000 miles. Scientists at the National Aeronautics and Space...

NASA's Near Earth Object Program Office at the Jet Propulsion Laboratory (JPL) offers this Webpage (for another similar page from JPL, see the March 13, 1998 Scout Report for Science & Engineering) containing relevant information on Near Earth Objects (NEO). The site includes current tables with tracking data for potentially hazardous asteroids and their approaches towards earth, detailed...

This site provides information related to the recently discovered asteroid 1997XF11. NASA's Near Earth Asteroid Tracking (NEAT) is an observatory in Maui, Hawaii. The site provides images and information about newly discovered asteroids, comets, and other unusual objects.

NeoDys, a project developed at the University of Pisa in Italy, supplies data and services for all Near Earth Asteroids. Updated daily, researchers can find links to all NeoDys objects and observatories as well as data on Earth Impact Possibilities. Educators and students will find instructive explanations of Near-Earth Asteroids and three dimensional visualizations of the objects' orbits....
