The planetarium show “Pluto & Some Planets” comes to the Edwin E. Ritchie Observatory at Battle Point Park at 8:30 p.m. Saturday, June 11.

Join astronomer Steve Ruhl as he examines the latest data on Pluto from the New Horizons spacecraft.

The show will also take a brief look at the three planets currently in the evening sky; Jupiter, Mars and Saturn.

There will also be special one-year anniversary kid’s shows at 5 and 6 p.m. with Dr. Erica.

If the sky is clear, astronomers will be on hand with telescopes for public star gazing afterward.

Admission is free to members of the Battle Point Astronomical Association; $2 donation suggested for nonmembers, $5 for families.

The Battle Point Astronomical Association is a nonprofit amateur astronomy organization that operates the Ritchie Observatory and John H. Rudolph Planetarium in the Helix House at Battle Point Park.
