There is also a "parallactic" libration, depending on the earth's rotation; and a species of nodding movement -- the "libration in latitude" -- is produced by the inclination of the moon's axis to her orbit, and by her changes of position with regard to the terrestrial equator.
Four hundred years ago, he realized that if Copernicus was right—that the Earth orbits the Sun—they could show it by observing the 'parallactic motion' of the nearest stars.
The team plans to use parallactic motion again in the future.
Now known as "Alcor B," the star was found with an innovative technique called "common parallactic motion," and was found by members of Project 1640, an international collaborative team that gives a nod to the insight of Galileo Gallilei.
Using a parallactic barrier in the LCD display, the AL3DU laptop can turn ordinary movies and photos into 3-D video and images.
Unless the deviations from the parallactic line of the stellar motions balance one another on the whole, their discussion may easily be as fruitless as that of observations tainted with systematic errors.
In order to determine the loss of energy attending the reflection of the rays by the diagonal mirrors, I have constructed a special apparatus, which, by means of a parallactic mechanism, faces the sun at right angles during observations.
Hipparchus, the parallactic rules of Ptolemy, Regimontanus Purbach, and
The mounting of the largest instrument was parallactic, but without divided circles, without clock-work, without clamp and slow motion.
The double ellipses are the images of the terrestrial orbit projected on the celestial sphere by the parallactic displacement of the stars and by the finite velocity of light.
