The planet Mercury transits the sun only about 13 times a century, and you can witness it Monday, May 9.
The Ritter Planetarium at The University of Toledo is helping the community mark the occasion with programs at 11 a.m., noon, 1 p.m. and 2 p.m. The 15-minute programs will be followed by a live-streaming image projected on the full-dome screen.
The Toledo Astronomical Association also will have a telescope with a solar filter on hand outside the planetarium so that people can see the transit live, weather permitting.
The planet will take about seven and a half hours to cross the sun. The last such transit was Nov. 8, 2006.
