Difference between Hipparcos and International Celestial Reference System

Hipparcos vs. International Celestial Reference System

Hipparcos was a scientific satellite of the European Space Agency (ESA), launched in 1989 and operated until 1993. The International Celestial Reference System (ICRS) is the current standard celestial reference system adopted by the International Astronomical Union (IAU).

Similarities between Hipparcos and International Celestial Reference System

Hipparcos and International Celestial Reference System have 5 things in common (in Unionpedia): Astrometry, Epoch (astronomy), Minute and second of arc, Quasar, Very-long-baseline interferometry.

Astrometry

Astrometry is the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies.

Epoch (astronomy)

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.
