Asteroid Juno Grabs the Spotlight
Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky. Those who get out to a dark, unpolluted sky will be able to spot the asteroid's silvery glint near the planet Uranus with a pair of binoculars.

"It can usually be seen by a good amateur telescope, but the guy on the street doesn't usually get a chance to observe it. This is going to be as bright as it gets until 2018" - Don Yeomans, manager of NASA's Near Earth Object Program Office at JPL.

Skywatchers with telescopes can probably see Juno from now until the end of the year, but it is most visible to binoculars in late September. On or before Sept. 21, look for Juno near midnight a few degrees east of the brighter glow of Uranus and in the constellation Pisces. It will look like a grey dot in the sky, and each night at the end of September, it will appear slightly more southwest of its location the night before. By Sept. 25, it will be closer to the constellation Aquarius and best seen before midnight.
