Diurnal parallax is a parallax that varies with the rotation of the Earth or with a difference in location on the Earth. The Moon and to a smaller extent the terrestrial planets or asteroids seen from different viewing positions on the Earth (at one given moment) can appear differently placed against the background of fixed stars. The diurnal parallax has been used by John Flamsteed in 1672 to measure the distance to Mars a… WebDec 20, 2024 · The definition of Parallax is that the 1 au radius of the Earth's orbit around the Sun causes an angular change of 1 arcsecond in the apparent position of a star that is 1 parsec distant. But this definition can be extended to any angular displacement.
