Asteroid Day is held each year on June 30, the anniversary of the largest asteroid impact in recent history, the 1908 Tunguska event in Siberia. 

There will be a meteorite expert on site evaluating rocks people bring in that might be from space.

There will also be meteorites on display and an impact cratering demonstrating. 

If the clouds clear, visitors can also take a look through the large Cronyn telescope to get a close-up look at the sun.
