Gravitational Microlensing

(gravitational lensing by "small" objects such as individual stars and planets)

Gravitational Microlensing is Gravitational Lensing by smaller objects, e.g., by stars within a Galaxy rather than the galaxy. The patterns by which individual stars affect the light from distant objects reveals information about the relative Proper Motion of the two objects as well as other physical phenomena such as mass.

Such microlensing is also used to detect Extra Solar Planets which can affect the light of stars passing behind them.
