Subject has value has definition

dynamical parallax The "parallax" (i.e., distance) for a binary star whose orbit is well known, derived by using the mass-luminosity relation and Newton's generalization of Kepler's third law.

horizontal parallax The difference between the topocentric and geocentric positions of an object, when the object is on the astronomical horizon.

secular parallax 4.09 AU per year A parallax based on solar motion; i.e., the baseline is the distance the Sun moves in a given interval of time with respect to the local standard of rest.

solar parallax 8.79 arcsecond Angle subtended by the equatorial radius of the Earth at a distance of 1 AU.
