Mercury passes Venus


Say goodbye to Mercury until it pops up in the dawn sky in July. The smallest planet can be found tonight to the lower left of Venus. Look to the west-northwest at 9:35 p.m. for Venus shining low above the horizon. Mercury lies to its left. Binoculars most likely will be need to spot i, though,t unless the sky is very clear. After tonight, it will be too low to spy its feeble light in the bright twilight. 

These two images were taken June 18 at 9:40 p.m.

Spotting Mercury as it rounds the sun


At 9:40 p.m. in the west-northwest, Venus can be easily found shining low above the horizon. The solar system's innermost planet, Mercury, while in the same general area, is not nearly so easily found. Over the next week, it drops quickly past Venus to the horizon as it orbits the sun. Mercury sits just to Venus' left on Tuesday night (June 18). Use binoculars to positively ID it since Mercury and Venus both glow in the same field of view. If conditions are very clear, binoculars may not be necessary to see Mercury.

In the image, taken at 9:40 p.m. on June 15, Mercury is seen to Venus' upper left.

Why not give Mercury spotting a try?

Monday night June 10, the moon provides a guide to locate the solar system's innermost planet, Mercury. At 9:20 p.m. look to the west-northwest for Venus and the thin crescent moon. If skies are clear, Mercury will be glimpsed above Venus and to the upper right of the moon. Binoculars will make the scene easier to see, but they are not essential.

Mercury is now at its highest in the early evening sky and drops towards Venus over the next week.

Three planets dance in the west


An unusual planetary grouping begins tomorrow night and lasts for a week or so. Very low in the west-northwest at about 9:05 p.m., three planets dance above the horizon. On May 26, bright Venus lies at the lower corner of an equilateral triangle. Jupiter, recently a bright object in the west, has sunk so that it now sits just to Venus' upper left. Dim Mercury occupies the final point of the triangle to the upper right of Venus. Binoculars may be needed to find Mercury's feeble light in the bright twilight.

As the nights pass, Jupiter drops from view until late July, while Mercury rises higher above Venus.
