Position of Mercury


Over the next week, Mercury presents itself climbing in the west-northwest each night. Look about 9:30 p.m., or slightly before for this little star-like object shining near the true stars of Pollux and Castor in Gemini. By 10 p.m. it will have dropped to low to find. 

On June 21st, Mercury lies half way between the thin crescent moon and Pollux. Two nights later, it forms a straight line with Pollux and Castor. By July 4th, it will be lost from view as it dips quickly towards the sun.

This is tough object to spot, especially in the summer haze. Binoculars are sure to help.

Such is our view from Earth...
