Mercury will briefly reveal itself before dawn tomorrow (June 16) when the planet reaches its longest separation from the sun as seen from Earth, also known as its largest western extension.

The elusive planet Mercury will reach a maximum angle of 23 ° west of the sun; viewers who are close to the equator and further south will experience the best viewing options.
