geocentric parallax
Technical term in astronomy; the apparent shift of a celestial body's position when observed from the Earth's center versus its surface.
To accurately determine the Moon's position, it is necessary to correct for geocentric parallax.
Heliocentric parallax, measured from the Sun's center, while 地心視差 is measured from the Earth's center.
Compound of 地心 (geocentric) and 視差 (parallax). The exact historical derivation is uncertain; the spelling is conventionally associated with the astronomical meaning.
