On February 22, 2019, you’ll have to stay up fairly late to view the moon and Spica, the constellation Virgo’s brightest star, rising into your eastern sky. At mid-northern latitudes, look for the twosome to be up by around 10 to 11 p.m. At more southerly latitudes, the moon and Spica will rise earlier in the evening.

Spica - Example - Star - Words - Stars
Spica serves as a prime example of a 1st-magnitude star; in other words, it’s one of the brightest stars in our sky. You should have little trouble picking it out, even in the glare of the waning gibbous moon, over these next few nights.
Keep watching, and try to recognize patterns of stars around Spica if you can. If you do, once the moon leaves the evening sky in another few days, you’ll easily note Spica’s color. It is a blue-white gem of a star, and, for stars, color reveals temperature. Spica’s blue-white complexion shows that its surface temperature is extremely high (39,860 degrees Fahrenheit, or 22,127 degrees Celsius). In contrast, our yellow-colored sun has a much cooler surface (only 9,980 degrees F, or 5,527 degrees C). The surface temperature of a red star, such as Antares, is even cooler (5,840 degrees F, or 3,227 degrees C).
