Between 19,6 and 11,000 lightyears.
No, it isn't in the Andromeda Galaxy. BTW, there's also an Andromeda constellation.

All the stars we can see in the sky are in our own galaxy, the milky way. Stars in other galaxies are so far away that no optical instrument can actually distinguish them from the galactic bulk even in andromeda which is our neighbour galaxy.
Cassiopea is a constellation, so no distance can be defined for it. Distance can only be defined to stellar objects like stars, nebulae, clusters and galaxies.

A constellation isn't a certain distance away; the constituent stars of the constellation are various distances away. For example, Alpha Cassiopeiae is 229 light-years from earth, while Beta Cassiopeiae, which is only slightly dimmer, is a mere 54.5 light-years away. There are some deep space object in the constellation that are thousands of light-years away. These stars are in our own galaxy.

Constellations cannot be measured that way. They are merely a pattern of stars that appear in the same area of the sky. However the stars in that group are many varying distances away from us. So it is not possible to measure how far a constellation is. You could measure each individual distance of each star I suppose, but in three dimensions and viewed from any other angle it would not look like the familiar group of stars we recognize as a constellation. They can be many many light years apart.
Sorry - that's the best I can do........ [groan]

Cassiopea is definitely in our galaxy. It is made up of many stars each at a varying distance. Some are 150 light years away and some are 40 light years away.

Constellation : Cassiopeia
Distance from Earth : ~ 2500 LY (light years)
Apparent angular size : huge !!
Check this site out they have some great photographs.
