Even the guide stars in Capricorn are fairly dim and obscure. Find Capricorn and then take a look about two-thirds of the way (3.3 degrees) down the front leg of Capricornus. Vesta will be brighter than any star within a degree of that spot. Here's how you can be sure you are looking at an asteroid and not a star: You can see Vesta moving. It's not immediately perceptible, but with patience you can see that Vesta is in a different place if you check on it over a period of time. Just by luck a distinctive appearance of stars will make this easy tonight. Once you've found Vesta, verify that there are two small 7th magnitude stars nearby (HIP104229 and HIP104216). Read more

Hot on the heels of last months' arrival of NASA's spacecraft Dawn at asteroid Vesta, backyard skywatchers throughout August get a chance to see the space rock for themselves in its best and brightest apparition until 2018. Vesta officially reaches opposition - opposite in the sky from the Sun, - on August 5 and will be at its brightest at magnitude 5.6 around that date- the most brilliant any asteroid can technically ever get in our skies.

Vesta reaches magnitude +5.6 on Aug. 6 and is visible to unaided eyes if you have a very dark sky and can pick out its dim speck of light from actual faint stars in the area. Binoculars will show it readily. The asteroid is currently travelling through the constellation Capricornus the Goat, which is seen in the south-southeast sky at about 11 p.m. as August begins.
