The Planets and Special Events

The Orionid Meteor Shower peaks on the night and early morning of October 20/21. The Orionid Meteors are associated with Comet 1P/Halley. Unfortunately the Last Quarter Moon will interfere this year.

A Public Star Party with telescopes provided by the Los Angeles Astronomical Society and the Los Angeles Sidewalk Astronomers will take place on the front lawn of the Griffith Observatory from 2 p.m. until 9:45 pm on Saturday Saturday October 5..

Venus (Mag -3.9) is still very close to the West-Southwest horizon and won't be easily visible until late in the month at which time it will be very bright at sunset.

Jupiter (Mag -2.0) can be seen in the southwest at twilight. It will set earlier each day throughout the month of October.

Mars (Mag +1.8) will appear low in the East later this month.

Saturn (Mag +0.5) is visible in the Southwest near Jupiter as darkness falls. Saturn's ring system is tilted 25 and well placed for viewing through a telescope.

Fun Facts

When you hear somebody talk about a celestial object being 30 (or 30 degrees) above the horizon, how in the world do you know how far up that is ? Well, hold your hand out at arms length with your thumb and fingers together, the palm of your hand facing you with the sky behind it. The distance from the edge of the little finger on the bottom of your palm to the edge of your thumb on the top is about 10 (10 degrees). Two palm widths is 20, three is 30 and so on.

The theory that our Sun is the center of the universe and our planets revolve around it was first documented by Nicolas Copernicus. The interesting thing is that Copernicus was a Catholic Priest and Philosopher, not an Astronomer. But he believed that God would have made the movements of the planets more simple than the previously documented theory (which was very complex). As we know today, Corpernicus was right !
