Earthsky.org - 9/8/13, Deborah Byrd
Tonight – Sunday, September 8, 2013 – there will be a very close pairing of the moon and Venus, especially as seen from the Americas. The moon and Venus will be seen from around the world, but, since the moon is moving in orbit around Earth, its distance from Venus on our sky’s dome will vary throughout that day. North and South America, and Europe, are all well placed for viewing this event. These are the brightest nighttime objects in Earth’s sky. They will be beautiful, no matter where you are on the globe.
Start looking for the moon and Venus about 30 minutes after sunset on September 8. Look west. Don’t wait too late because, especially from latitudes in the Northern Hemisphere, Venus soon follows the sun below the western horizon.
