Epsilon Crateris

Epsilon Crateris (ε Crateris) is a solitary^[12] star in the southern constellation of Crater. Visible to the naked eye, it has an apparent visual magnitude of 4.84.^[2] It is located in the sky above Beta Crateris, and slightly to the left, or east, marking the lower right edge of the rim of the bowl and is somewhat closer to Theta Crateris, which is further east at the top of the bowl. With an annual parallax shift of 8.67^[1] mas as seen from the Earth, its estimated distance is around 376 light years from the Sun.
