- Using it as a common noun (e.g., 'a hipparchus satellite').
FAQ
Frequently Asked Questions
The official mission name is 'Hipparcos', an acronym for 'High Precision Parallax Collecting Satellite'. It is named in honour of the ancient Greek astronomer Hipparchus.
It is the primary output of the mission—a database containing precise positions, parallaxes (distances), proper motions, and brightnesses for 118,218 stars.
Hipparcos (1989-1993) was the pioneering space astrometry mission, measuring about 120,000 stars. Gaia, launched in 2013, is its vastly more powerful successor, measuring over a billion stars with even greater precision.
It provided the first large-scale, highly accurate map of stellar positions and distances from space, revolutionizing fields like stellar astrophysics and galactic structure, and laying the groundwork for the Gaia mission.
The first satellite designed to measure the precise positions, motions, distances, and colors of stars with unprecedented accuracy.
Hipparchus satellite is usually technical/scientific in register.
Hipparchus satellite: in British English it is pronounced /hɪˈpɑːkəs ˈsætəlaɪt/, and in American English it is pronounced /hɪˈpɑrkəs ˈsæt̬əlˌaɪt/. Tap the audio buttons above to hear it.
