Orion
(well-known constellation in the northern hemisphere)
Orion is a well-known, conspicuous constellation visible from
both hemispheres (spanning the equator)
named for the hunter from ancient Greek mythology, Orion.
It includes a number of prominent stars:
The latter three sit in a distinct row imagined as the hunter's belt,
an asterism making the constellation evident.
One of Orion's other "stars" is actually Orion Nebula,
which appears to be the middle star of a line of three
imagined to be Orion's sword, descending from the belt.
The nebula hosts some of the nearest
star-forming regions which include many objects of high
interest to astrophysics.
