of the known orbital and physical properties of
all NEAs, together with information for calculating
their future close approaches to the Earth. Updated
This Program Office was established
in mid-1998 to help coordinate, and provide a focal
point for, the study of those comets and asteroids
that can approach the Earth's orbit.
This site contains Documents,
a Bulletin Board, Links and a Photo Gallery all
dealing with the Tunguska event.
LONEOS, operated by Ted Bowell
at Lowell Observatory, is a system designed to find
NEOs as part of the Spaceguard Survey.
This is on Space Resources, which
is not directly our subject, but it looks like a
good page for general NEO stuff.
NEAT is an autonomous celestial
observatory located at the USAF/Ground-based Electro-Optical
Deep Space Surveillance (GEODSS) site on Haleakala,
Maui, Hawaii. NEAT is a cooperative effort of NASA,
JPL, and the USAF.
Spaceguard UK is a private organization
that serves as the national focus in the UK for
studies of the impact hazard.
An association aimed at the protection
of the Earth environment against the bombardment
of objects of the solar system (comets and asteroids).
"The MPC is responsible
for the collection and dissemination of astrometric
observations and orbits for minor planets and comets."
"EARN is an informal association
of European research groups active in asteroid research.
The idea behind this service is to provide a means
for easy and fast communication, exchange of data
and other information in both observational and
theoretical research on asteroids."

Under the direction of Tom Gehrels
and Bob McMillan, the University of Arizona's
Spacewatch Observatory pioneered in the automated
discovery of NEAs.
