The planetarium show “Jupiter & the Trojans” will be presented at 7 p.m. Saturday, Nov. 10 in the Edwin E. Ritchie Observatory at Battle Point Park.

Jupiter, the largest planet in the solar system, is now rising in the eastern sky. Steve Ruhl, president of the Battle Point Astronomical Association, will talk about the spectacular planet’s structure, its more than 60 moons, and its influence on asteroids and other bodies in the solar system, including Earth.

If the sky is clear, the group will also check out the real thing through the telescopes of BPAA astronomers.

The show is free to members; $2 donation suggested for nonmembers, $5 for families.
