Draco, "the Dragon," is a sinuous
constellation that winds its way among the circumpolar constellations.
Face north and look high in the sky. Find the Big Dipper (Ursa Major), our March 2013
Constellation of the Month. The open
part of the bowl of the Big Dipper faces the smaller bowl of the Little Dipper
(Ursa Minor). The tail of Draco is about
halfway in between. Draco is comprised
relatively faint stars – more of the brightness of the stars of the Little
Dipper than those of the Big Dipper.
Follow the tail south, in the direction of Hercules, our July 2013. Then, Draco curves north in an arc around the
Little Dipper, heading toward Cepheus our October 2013 constellation. Then, Draco curves south again and ends with
a "head" formed by a quadrilateral of stars near Hercules.
The head is east of Vega, the very bright
star in the constellation Lyra, our August 2013
constellation. The 4 stars in the head
are among the brightest in the constellation.
That, and its compact size, makes the head relatively easy to find. So, you may want to start there, if you're
having trouble finding the tail.
Draco is home to the Cat's Eye Nebula, NGC
6643. This is a Planetary Nebula, which is the remnant of an
exploded star. A Hubble Telescope photo shows a complex interplay
of shapes structure, within the roughly spherical shape of the nebula.
