Iota Ursae Majoris is a star system composed of two double stars, a white subgiant of the spectral type A7 IV that is in fact a spectroscopic binary, and another pair of 9th and 10th magnitude stars. When the B component was first discovered in 1841, the two binary stars were separated by 10.7 arc seconds. The distance between the two has decreased dramatically since, and is now only 4.5 arc seconds. The two components orbit each other with a period of 818 years. Iota Ursae Majoris is approximately 47.3 light years distant from the solar system.

How to speed up to Spica?

To do this, find the Big Dipper and take a look at the arc that is formed by the Dipper’s three handle stars (these would be Alioth, Mizar, and Alkaid).

How far away is Arcturus from Earth?

As far as stars go, Arcturus is pretty close to us at only about 37 light-years away — appreciably more than the 4 or 8 light-years of Alpha Centauri or Sirius, respectively. But it’s much closer than the hundreds of light-years that separate us from other red giants such as Betelgeuse or Antares. This proximity to Earth is certainly a contributing factor to Arcturus’s apparent brightness. In fact, Arcturus is the fourth-brightest star in the night sky, outshone only by Sirius, Canopus, and Alpha Centauri, and the second brightest for much of the Northern Hemisphere.

Where is Arcturus in the sky?

Arcturus is a fine spring and summer star, riding high in the southwest around Summer Equinox. But it’s also a nice autumn star, hanging lower in the west just after sunset in the fall.
