There isn't a single queen who became a constellation. The stories of constellations are often based on myths and legends, and many of them involve queens, heroes, and other figures from ancient mythology.

However, some of the most famous constellations associated with queens are:

* Cassiopeia: In Greek mythology, Cassiopeia was the queen of Ethiopia who boasted about her beauty, angering the sea nymphs. She was punished by being chained to a celestial throne and forced to eternally circle the North Star.

* Andromeda: Andromeda was a princess who was chained to a rock as a sacrifice to the sea monster Cetus. She was rescued by Perseus, and both were placed in the sky as constellations.

It's important to remember that these are just myths, and the constellations were named and given these stories after people started observing the stars.
