The closer objects are to each other, the greater their gravitational force of attraction, and as they get farther apart, the force between them becomes weaker. Even though the Sun is much more massive than Earth, the distance betwee ...

The first quasar found has the unromantic designation, 3C273, and it was discovered by a radio telescope when the object disappeared behind the moon during a lunar occultation. Quasi-stellar radio sources, or quasars, are amazingly faint ...

Lunar theory

Lunar theory attempts to account for the motions of the Moon. There are many irregularities (or perturbations) in the Moon's motion, and many attempts have been made to account for them. After centuries of being problematic, lunar motion is now modeled to a very high degree of accuracy (see section Modern developments).Lunar theory includes: the background of general theory; including mathematical techniques used to analyze the Moon's motion and to generate formulae and algorithms for predicting its movements; and also quantitative formulae, algorithms, and geometrical diagrams that may be used to compute the Moon's position for a given time; often by the help of tables based on the algorithms.Lunar theory has a history of over 2000 years of investigation. Its more modern developments have been used over the last three centuries for fundamental scientific and technological purposes, and are still being used in that way.
