The 58 pages that link to Astrometry, each with the reason it gives.

• Tau CetiRelated: Astrometric measurements constrain Tau Ceti’s distance, motion, and stellar characteristics.

• Andrea M. GhezRelated: Ghez’s team used astrometry to chart stars’ changing positions around the central source.

• Astronomical nutationNarrower topic: Accurate astrometry requires accounting for nutation’s shifts in the celestial coordinate frame.

• Heinrich Wilhelm Matthias OlbersNarrower topic: Precise positional measurements underpinned Olbers’s discovery and tracking of asteroids.

• Minute and second of arcRelated: Arcseconds and smaller units express the precision of celestial positions.

• Nibiru cataclysmRelated: Repeated positional measurements would reveal a large planet before a close encounter.

• Pi PuppisRelated: Precise positions and motion help characterize the components of Pi Puppis.

• Zeta OphiuchiRelated: Astrometric measurements constrain the star's speed and trace its trajectory backward.
