General presentation

Its position near the north celestial pole makes it visible for much of the year, and it never completely disappears below the horizon for many observers. Cassiopeia is widely used as a reference point in the sky because it is located opposite Ursa Major in relation to the North Star. It thus makes it easy to orient oneself, even without instruments.

Shape of the Cassiopeia constellation

The constellation of Cassiopeia has a very characteristic W or M shape, depending on its position in the sky. This form consists of five relatively bright main stars that draw a broken line easily identifiable. This zigzag-shaped visual signature is what makes Cassiopeia so easy to recognize, even for beginners. Unlike other constellations that require an effort of imagination, Cassiopeia is directly visible as a geometric figure in the sky.
