Glossary

Astronomical Unit (AU):

middle distance between Earth and Sun, equal 149.6 millions km.

Eccentricity:

a parameter that specifies the shape of a conic section; one of the standard elements used to describe an elliptic orbit.

Ecliptic::

the mean plane of the Earth's orbit around the Sun.

Inclination::

the angle between an orbital plane and the ecliptic plane.

Perihelion::

the point at which a body in orbit around the Sun most closely approaches the Sun.

Period:

the interval of time required to complete one revolution in an orbit or one cycle of a periodic phenomenon, such as a cycle of phases.


Comet search projects:

LINEAR:

The Lincoln Near Earth Asteroid Research project.

LONEOS:

The Lowell Observatory Near-Earth Object Search.
