Suzanne Wilson, 11, of Cheyenne, Wyo., for her question:

WHO NAMED THE SEVEN SISTERS CONSTELLATION?

A cluster of stars called the Seven Sisters is 490 light years away. Also called Pleiades, about 200 stars may be seen in the constellation with a telescope, but only six stars can easily be seen with the eye alone.

Pleiades, which is sometimes mistaken for the Little Dipper, received its name from a Greek myth.

According to the story, Zeus transformed the seven daughters of Atlas into doves, and then into stars to enable them to escape the attention of Orion. The sisters were Alcyone, Merope, Celaeno, Taygeta, Maia, Electra and Sterope.

Legend says that only six of the stars can be seen because Merope hid herself in shame over marrying a mortal.
