Astronomy Calendar of Celestial Events

There is always something interesting happening in the sky. This astronomy calendar contains dates of notable events: including moon phases, meteor showers, comets, eclipses, oppositions, and conjunctions. Planetary, solar, astronomical, and spacecraft events will also be identified.

Some astronomical events on this calendar can be seen with the unaided eye, and others may require a good pair of binoculars, or a telescope, for best viewing.
