Definition of astrometry in English:

astrometry

noun əˈstrɒmɪtriəˈstrɑmətri

mass noun

The measurement of the positions, motions, and magnitudes of stars.
Example sentencesExamples
- One technique, known as astrometry, involves precisely measuring the position of a star.
- The main branches are astrometry, celestial mechanics, and astrophysics.
- This method, known as astrometry, is the oldest planet-hunting method, but no planets have yet been found based on it alone.
- In this way, astronomers will perform very precise astrometry to detect the reflex motion of stars due to orbiting planets.
- And while methods such as photometry and astrometry, which hold great promise in the long term, are still being perfected, other innovative approaches are already yielding results.

Derivatives

astrometric

adjective

It was designed to produce extremely accurate astrometric measurements in small fields, and has been used to measure parallaxes and therefore distance for faint stars.
Example sentencesExamples
- After obtaining the images, she used astrometric software to determine the coordinates of the target asteroid's apparent position in each image.
- The main objective of the astrometric instrument (ASTRO) is to obtain accurate measurements of the relative positions of all objects that cross the fields of view of Gaia's two telescopes.
- To date there have been no successful detections of extrasolar planets with the astrometric method.
- Tycho had collected in one place the finest astrometric instruments of his day - four decades before Galileo introduced the astronomical telescope.
