The Planets in Autumn
The next few months will offer exceptional planetary viewing, highlighted by Saturn reaching opposition (the point when the Sun, Earth, and Saturn form a straight line space with Earth in the middle) and by prominent evening appearances of Venus and Mars.
- Saturn reaches opposition on October 3–4 and remains visible all night, with its rings well positioned for observation.
- Venus is our “Morning Star” in November. Look east 45-90 minutes before sunrise. On Nov. 20, it reaches maximum brilliance. On Nov. 7, an hour before sunrise, the crescent moon hangs just below Venus, making for a great photo op.
- Jupiter appears in the morning sky, where you can see its moons moving closer together. On Oct. 6, the Moon will pass in front of Jupiter, briefly hiding it from view–a rare event called a lunar occultation.
- Mars is visible in the late night and early morning hours, moving across Taurus, Gemini, and Cancer.
World Space Week – October 4-10
The world’s largest annual space event, World Space Week is the United Nations’ official celebration of space and the use of technology to help humanity. This year’s theme is “Rocket Revolution.” Check out their website at worldspaceweek.org.
The Orionid Meteor Shower peaks on October 21/22
This meteor shower is expected to produce 15 to 20 meteors per hour and will be active from October 2 to November 7. The origin of these meteors is Halley’s Comet (1P/Halley). Unfortunately, during the peak, the Moon will be mostly illuminated (Waxing Gibbous at 80%), brightening the night sky and potentially washing out the fainter meteors. Look near the constellation Orion after midnight until 5 a.m.
The Leonid Meteor Shower peaks on November 17-18
This meteor shower is expected to produce 10 to 15 meteors per hour and will be active from November 6 to the 30th. The origin of these meteors is debris from comet Temple-Tuttle. These will be bright meteors that leave glowing trains in the sky. During the peak, the Moon will set before the show really begins. Look to the southern sky near the constellation Leo after midnight until 5:30 a.m.
Voyager 1 Reaches One Light-day from Earth
At some point in November, NASA’s Voyager 1 spacecraft, still active almost 50 years after its 1977 launch, will reach 25.9 billion kilometers (16.1 billion miles) from Earth. At this distance, light will take a full day to travel between our planet and Voyager 1.
