Examples of 'proper motion' in a sentence
Meaning of "proper motion"
In astronomy, the term 'proper motion' refers to the observed motion of a celestial object, such as a star, relative to other objects in the sky. It is the apparent change in the position of the object over time, due to its actual motion through space. Proper motion is measured in units of angular displacement per year and is an important parameter for studying the dynamics of stars and galaxies
