Where to Go
What to Bring
While stars twinkle, planets reflect a steady light. They can be seen along a low path in the sky, never higher than 30 degrees above the horizon. (Holding your fist out at arms length with the thumb on top is approximately 10 degrees. Three fists will equal about 30 degrees.)
The planet Venus, often seen just after sunset and just before sunrise, is the second brightest object in the night sky, next to the moon. Mars, Jupiter, and Saturn can often be seen later at night.

Man-made satellites can often be spotted crossing the night sky. Look for a bright, steadily moving object that does not twinkle and is moving in a straight line. Communications satellites orbit the earth moving east to west. Military satellites travel north to south.
"Shooting stars" and "falling stars" are both terms describing meteors, small fragments of debris that create streaks of light across the sky when they come in contact with the Earth's atmosphere. Shooting stars can be seen any night of the year, but the best opportunities for seeing them are during meteor showers.
The meteor showers that usually offer the best shows are the Perseids in August, the Orionids in October, the Leonids in November, and the Geminds in December. Meteor showers are named after the constellation they appear to originate from.
