| Asteroid - One of many small rocky bodies orbiting
the Sun; a concentration of these bodies makes up the Asteroid
Belt between Mars and Jupiter. |

- Near
Earth Asteroid Program the web page of NASA's Near-Earth
Object Program Office at the Jet Propulsion Laboratory. 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. The Earth's mean
orbital distance from the sun is defined as an astronomical
unit (1 AU) or approximately 93 million miles. Near-Earth Objects
(NEOs) are generally defined as those objects whose close approaches
to the sun are 1.3 AU or less. As a result, Near-Earth Objects
are those comets and asteroids that can come within about 28
million miles of the Earth's orbit.
- NEAR
Earth Asteroid Rendezvous NEAR is conducting the first
long-term, close-up study of an asteroid. Using innovative sensors
and detection equipment, NEAR is collecting information on Eros'
mass, structure, geology, composition, gravity and magnetic
field. The NEAR mission aims to answer fundamental questions
about the nature and origin of the many asteroids and comets
close to Earth's orbit. These "near Earth" objects may contain
clues about the formation of Earth, other planets, even the
whole universe. Eros' pristine surface offers a look at conditions
in space when Earth was formed more than 4.5 billion years ago.
- Meteorite
Central The latest information on Meteorites and the
impact that they have on our planet. If you want to find a Meteorite
this is the place to go. If you think you have found a Meteorite
this is the place to find the facts.
- International
Meteor Organization The International Meteor Organization
(IMO) was founded in 1988 and has more than 250 members now.
IMO was created in response to an ever growing need for international
cooperation of meteor amateur work
- The
Torino Scale The Torino Scale is a "Richter Scale"
for categorizing the Earth impact hazard associated with newly
discovered asteroids and comets. It is intended to serve as a
communication tool for astronomers and the public to assess the
seriousness of predictions of close encounters by asteroids and
comets during the 21st century.
