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.

Mean Distance:

the semimajor axis of an elliptic orbit.

Opposition:

a configuration of the Sun, Earth and a planet in which the apparent geocentric longitude of the planet differs by 180° from the apparent geocentric longitude of the Sun.

Semimajor Axis:

half the length of the major axis of an ellipse; a standard element used to describe an elliptical orbit.

Note: All time moments are given in Universal Time (UT) units.
For Kyiv Local_Time=UT+2^h (and Local_Time=UT+3^h for summer time).
