Cassiopeia, the Mother of Andromeda (Cas)


The Northern constellation of Cassiopeia, the Mother of Andromeda, is best viewed in Fall during the month of November. It's brightest star is Schedar at magnitude 2.24. The boundary of the Cassiopeia constellation contains 14 stars that host known exoplanets.

Cassiopeia is a circumpolar constellation, so is visible year-round in the Northern hemisphere. Conversely, it is not visible in the opposite hemisphere unless you are close to the equator.

                * Constellation shown for northen hemisphere skies. For the southern hemisphere, constellations appear rotated 180 degrees (upside-down and left-right reversed) from what is shown. Remember that seasons are reversed too - summer in northern latitudes is winter in southern latitudes.

                ** Circumpolar constellations are visible year-round in the hemisphere listed (and not at all in the opposite hemisphere).
