Omicron Draconis, also known as 47 Draconis, is a double star in the constellation Draco. The primary star shines an orange/red hue. Also, let’s pretend you are standing on the planet Mercury and not melting. The “north star” on Mercury is Omicron Draconis as it’s the closest star to Mercury’s north celestial pole. My ObservationsContinueContinue reading “Omicron Draconis (47 Draconis): Mercury’s North Star”

Dziban (31 Draconis)
Dziban is a double star in constellation Draco. It’s also know as 31 Draconis or Psi Draconis. The name Dziban is derived from Arabic “Adh-Dhi’ban,” which means “the two wolves.” This double is bright enough, and wide enough, to be viewed using binoculars. In 2015, astronomers discovered an exoplanet orbiting the secondary star (the dimmerContinueContinue reading “Dziban (31 Draconis)”
Spica: Beautiful Blue Light of the Spring Night
On spring nights, the solitary blue star Spica rises in the eastern sky standing seemingly alone in the constellation Virgo. Spica will always be a special star to me. You see, in my teenage years, I stayed up into the early morning hours to catch a last glimpse of the Orion Nebula and other deepContinueContinue reading “Spica: Beautiful Blue Light of the Spring Night”
Nu Draconis: A Bright Double Shines Like Diamond Earrings
Most double stars are too dim, or close together, to identify with an average pair of binoculars. A few, however, can be enjoyed this way. The ever popular Mizar in Ursa Major comes to mind. Another double star bright enough with good separation is Nu Draconis in Draco. The individual stars, called ν1 Draconis and ν2 Draconis,ContinueContinue reading “Nu Draconis: A Bright Double Shines Like Diamond Earrings”
41 Draconis: Creamy-Looking Double Star in Draco
40 and 41 Draconis form a double star system in the constellation Draco. Since they have fairly bright magnitudes and good separation, most observers with small telescopes should be able to split this pair. I suggest first-time observers first study their pale-yellow color. Some observers have noted they are a cream color. Then, slew yourContinueContinue reading “41 Draconis: Creamy-Looking Double Star in Draco”
Struve 1825: A Close Orange and Yellow Double in Boötes
Struve 1825, sits near the bright star Arcturus and has an orange and yellow pair sitting in Boötes.
Gamma Virginis “Porrima”: Twins Pulling Apart
Not far from Virgo’s beautiful blue Spica is the double star Gamma Virginis. Also known as Porrima, this star is the second brightest in the springtime constellation of Virgo. At first glance, from a suburban location with light pollution, Porrima appears as a dim, white star. However, looking through the telescope, one will find twoContinueContinue reading “Gamma Virginis “Porrima”: Twins Pulling Apart”
Mizar: A Double Star Known for Generations
My guess is Mizar is the first double star most people ever see. When Ursa Major (the “Big Dipper”) takes its place high in the springtime sky, casual skygazers can point out the bright double star in the middle of the ladle called Mizar. Its companion, called Alcor, shines almost as bright, making both starsContinueContinue reading “Mizar: A Double Star Known for Generations”
