No because microlensing requires the object being to be producing a light source and a plant doesn't. Even if a planet were reflecting light it wouldn't be enough to be seen.
Gravitational microlensing has not yet been used to detect planets around other stars. This method involves the gravitational deflection of light from a background star due to the presence of a foreground object, such as a planet, but no planets have been directly detected using this technique.
Wobble,transit,and gravitational microlensing
Planets around other stars are typically detected through indirect methods, such as the transit method (observing a star's brightness dip as a planet passes in front of it) or the radial velocity method (observing the star's wobble caused by the planet's gravitational pull). Other techniques include gravitational microlensing and direct imaging using specialized telescopes.
microlensing can be produced by MACHO's
Exoplanets are currently being detected using various methods, including the transit method (detecting the decrease in a star's brightness as a planet passes in front of it), the radial velocity method (measuring the wobble of a star due to the gravitational pull of an orbiting planet), and the direct imaging method (taking pictures of exoplanets themselves). Other techniques like microlensing and astrometry are also used to detect exoplanets.
Discovering the essential Universe by Neil F. Comins fourth edition Extrasolar planets can be discovered by observing them indirectly by using microlensing, by observing the Doppler shift of the star due to the pull of the orbiting planet, by observing the periodic variation of the proper motion of a star, and by observing the periodic variation of the starlight due to the planet passing between that star and Earth, an event called a transit.
Microlensing is an astronomical phenomenon due to the gravitational lens effect. Microlensing can be produced by MACHO's. and for your last question...idk Im doing my science homework now and I have the same question and I'm stuck. Hope my other answers helped!
Pluto, was detected in 1938. It was discovered as a planet since 1938, but in 2007 it was declared not a planet.
No life has been detected except on the planet earth.
