Difference between Epoch (astronomy) and Sun

Epoch (astronomy) vs. Sun

In astronomy, an epoch is a moment in time used as a reference point for some time-varying astronomical quantity, such as the celestial coordinates or elliptical orbital elements of a celestial body, because these are subject to perturbations and vary with time. The Sun is the star at the center of the Solar System.

Similarities between Epoch (astronomy) and Sun

Epoch (astronomy) and Sun have 10 things in common (in Unionpedia): Apsis, Astronomy, Earth, Ecliptic, Equator, Julian year (astronomy), Perihelion and aphelion, Perturbation (astronomy), Sirius, Sun.

Apsis

An apsis (ἁψίς; plural apsides, Greek: ἁψῖδες) is an extreme point in the orbit of an object.

Ecliptic

The ecliptic is the circular path on the celestial sphere that the Sun follows over the course of a year; it is the basis of the ecliptic coordinate system.

Equator

An equator of a rotating spheroid (such as a planet) is its zeroth circle of latitude (parallel).

Julian year (astronomy)

In astronomy, a Julian year (symbol: a) is a unit of measurement of time defined as exactly 365.25 days of SI seconds each.

Perihelion and aphelion

The perihelion of any orbit of a celestial body about the Sun is the point where the body comes nearest to the Sun.

Perturbation (astronomy)

In astronomy, perturbation is the complex motion of a massive body subject to forces other than the gravitational attraction of a single other massive body.
