It has been seen that the parallaxes afford little information as to the distribution of the main bulk of the stars and that the chief evidence on this point must be obtained indirectly from their proper motions.

For stellar parallaxes see Star; the solar parallax is discussed below.
Cassini's new method of parallaxes was inserted in the Ada Eruditorum of Leipzig in 1685.
As early as 1573, Thomas Digges had suggested that this theory should necessitate a parallactic shifting of the stars, and, consequently, if such stellar parallaxes existed, then the Copernican theory would receive additional confirmation.
