us as we celebrate our smallest planet Mercury as he makes his presence known this year and transits across the sun on May
9th. Mercury transits the sun much more often than Venus about 13 to 14 per century and
they happen in May and November. We will also watch him hang out with
the moon in April and September and with Jupiter in August.
Like Venus, he appears at the horizon (low) at sunrise or sunset these are called elongation. To
catch him at sunrise or Greatest Western Elongation (meaning west side of the sun) on Feb 2nd; Jun 5th; and Sep
28th. To see him at sunset or Greatest Eastern Elongation (meaning east side of the sun) look for him on
Apr 18th; Aug 16th and Dec 11th.
The Lunar and Planetary Institute
has a catalog of maps of Mercury, it will be great to talk about all his cratered surface.
A log sheet to draw his phases is provided in the resource section for a great hands-on activity. He
will have the same look like Venus and the moon!
