type: Concept
contributor: AAS Frey.Katie
broader: Diurnal parallax
definition: The angle under which the radius of the Earth at the place of observation would be seen from a celestial body when it is in the horizon (at the instant of rising or setting). The amount varies with the latitude since the Earth is not exactly spherical, and is greatest at equator.
