August 30: The Moon, Neptune, and Saturn
Within the night sky, blazing Venus is lower than 2° southwest of Spica, the brightest star in Virgo the Maiden. Over the course of the following two days, Venus will seem to slip to the higher left (east) within the sky relative to stationary Spica, remaining inside roughly 2° of the star because it does so.
The pair is simple to identify within the west as quickly because the Solar goes down and the sky begins to develop darkish. At magnitude –4.6, Venus will come out first, roughly 12° above the horizon 20 minutes after sundown. Magnitude 1.0 Spica will take a bit extra time to look — use the chart above to notice its place, and see how quickly you possibly can see it.
You may as well benefit from the pair by binoculars or a telescope. Within the latter, Venus will present a 39%-lit disk that stretches some 30” within the sky, a powerful dimension. It’s presently some 0.55 astronomical unit from Earth, the place 1 astronomical unit, or AU, is the typical Earth-Solar distance of 93 million miles (150 million kilometers).
