70 Ophiuchi -- Double Star in Ophiuchus
Colorful Double Star in Ophiuchus
The sky is full of double stars.  Star Systems are more likely to have two or more stars
gravitationally bound to each other, than to exist as a single lone star like our sun.  Most
observers, myself included, enjoy finding and observing these multiple star systems,
especially when a pretty color contrast exists between the stars.  70-Ophiuchi is just such
a pair; providing a pretty yellow-orange and an orange-red contrast.  Both stars in the
70-Ophiuchi system are dwarf-stars and only appear reasonably bright because they are
so close, only 16.6 light-years from Earth.
