Linked from

The 31 pages that link to Stellar parallax, each with the reason it gives.

• AstrometryRelated: Its annual angular shift gives astrometry a direct geometric method for measuring stellar distance.

• Tycho BraheRelated: Brahe found no detectable annual stellar parallax, a central objection to a moving Earth in his time.

• Nicolaus CopernicusRelated: Its absence from Renaissance observations was a major objection to a moving Earth.

• Absolute magnitudeRelated: Parallax distances allow absolute magnitudes to be calculated for nearby stars.

• HeliocentrismRelated: Its eventual measurement confirmed that Earth moves around the Sun.

• Stellar radiusRelated: It provides the distance scale required for a physical radius measurement.

• Women in astronomyRelated: Henrietta Swan Leavitt’s distance scale helped extend measurements far beyond parallax’s reach.

• GeocentrismRelated: Its eventual measurement confirmed Earth’s orbital motion, though its absence initially favored geocentrism.

• PolarisRelated: Different parallax measurements have produced debated estimates of Polaris’s distance.

• ParsecRelated: A star’s parallax angle determines its distance in parsecs.

• Alpha CentauriRelated: It provides the geometric basis for measuring Alpha Centauri’s distance.

• Proxima CentauriRelated: Parallax measurements establish Proxima’s distance from Earth.

• StarRelated: Parallax provides direct distances to nearby stars.

• Aristarchus of SamosRelated: An undetected parallax was used to challenge heliocentrism, prompting the possibility that stars were extremely distant.

• PleiadesRelated: Parallax provides a direct geometric route to measuring the cluster’s distance.

• Yerkes ObservatoryRelated: Yerkes astronomers used precise observations to improve measurements of stellar distances.

• Henry Norris RussellRelated: Parallax provides distances for calculating luminosities, complementing Russell’s use of spectral evidence.

• RigelRelated: Parallax measurements help establish Rigel’s distance, though its large distance makes precision challenging.

• AldebaranRelated: Parallax measurements establish Aldebaran’s distance from the Solar System.

• Stellar astronomyRelated: Parallax supplies direct distances that anchor estimates of stellar luminosity.

• Local BubbleRelated: Parallax maps nearby stars and helps establish the Bubble's structure and scale.

• SN 1572Related: Tycho’s failure to detect parallax helped place the new star beyond the Moon.

• SubdwarfRelated: Parallax distances allowed astronomers to establish that some stars were intrinsically underluminous.

• Timeline of cosmological theoriesRelated: Its eventual measurement supported Earth's motion and the vast scale of the stellar universe.
