| | Atlas |
 | | Atlas, 425 light years away (as is the rest of the cluster), is (at class B8) a bit on the cooler side (for the class), with a temperature around 12,300 Kelvin. |
 | | Like the other naked-eye Pleiades (well, Dad actually), Atlas is brilliant, radiating 940 times as much light as the Sun, much of it in the invisible ultraviolet, the luminosity and temperature telling of a star with a mass about 5 times solar. |
 | | Atlas has a reputation as something of a mild "B-emission" star, implying a ring of radiating material formed as a result of its rapid rotation. |
