  Glossary
Astronomical unit (a.u.):
middle distance from Earth to 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.
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.

Home Note: All the times in this page are expressed in universal time (UT).
For Kyiv Local_Time=UT+2h (and Local_Time=UT+3h for summer time).
