Gravitational microlensing - Wikipedia
Gravitational microlensing is an astronomical phenomenon caused by the gravitational lens effect. It can be used to detect objects that range from the mass of a planet to the mass of a star, regardless of the light they emit.

The effect is extreme around very massive objects, like black holes and entire galaxies. But even stars and planets cause a detectable degree of warping, called microlensing.
Space-Warping Planets: The Microlensing Method
Microlensing is capable of finding the most distant and the smallest planets of any currently available method for detecting extrasolar planets. In January 2006 scientists announced the discovery through microlensing of a planet of only five Earth masses, orbiting a star near the center of our galaxy, 22,000 light-years away!

Microlensing refers to the special case of GRAVITATIONAL LENSING where the multiple images produced are too close together on the sky to be observed as separate images. However, the lensing can still be detected because these multiple images appear as a single object of increased apparent brightness.
