There are two planets visible as soon as the Sun sets this summer. Jupiter and Saturn are brighter than all of the surrounding stars, and will probably be the first objects you notice on a clear night. Jupiter is the brighter of the two, and visible in the southwest.
Jupiter stands out in the southwest when the Sun sets, because it is so much brighter than any star nearby. Image: Stellarium and me |
Jupiter appears in the constellation of Virgo the Maiden, for which Spica is the brightest star. Arcturus is the red-orange star above. |
Saturn is visible in the SSE as soon as the Sun sets. |
Saturn is near Scorpius in the summer sky. |
These two planets will be the brightest objects visible in our summer sky besides the Moon. However, the 4th and 5th brightest stars in the night sky are also visible right now. These stars shine through even city light pollution, so try to find them in your backyard on the next clear night!
Look high in the west to find the orange star Arcturus, the 4th brightest in the night sky. Arcturus is a spring star, but so far to the north that it stays visible most of the summer. You can follow the curved handle of the Big Dipper to make sure you've spotted the right star. Follow the "arc" to Arcturus, and you have found the constellation of Bootes.

The constellation of Bootes is supposed to represent a man, but it doesn't really look like one. Can you see a kite? Or a necktie? |
I like to think of Bootes as an ice cream cone. |
On the opposite side of the sky, high in the east, you can spot the bright blueish star Vega. Vega is the 5th brightest star in the night sky, because it is only 25 light years away, and is very hot. Thousands of years in the past, Vega was the North Star, not Polaris. It will be the pole star again thousands of years in the future. Read more about pole stars here.
Vega is the brightest star in the constellation of Lyra the Harp. See star chart below.
Vega is the brightest star high in the east. |
In the city, you can find Vega easily, and on a clear night, the four stars in a trapezoid shape below Vega. |
These four objects - two planets and two bright stars - are great targets for beginning stargazers to try to find this summer!
