Mercury reaches greatest   Thursday

elongation' before dawn on

Mercury will briefly reveal 

itself at pre-dawn tomorrow (June 16) when the planet reaches its farthest separation from the sun as seen from Earth

Mercury will

 be nearly as far from the sun on the surrounding mornings

Between about 4:30 and 

5 a.m. in your local time zone, look for the magnitude 0.45 planet shining very low in the east-northeastern sky

Exact time of event  

varies depending on your specific location, so you'll want to check out a SkySafari app or  Starry Night software 

Mercury is usually tricky

 planet to spot as its orbit lies closer to the sun than Earth's, and is often obscured by the sun's glare

Mercury zips around sun

 every 88 Earth days, traveling through space at nearly 112,000 mph (180,000 km/h), faster than any other planet
