Some of it is self explanatory, but there is confusion about the difference between OSD and DoD Components. Points to keep in mind when writing or revising a DoD issuance are: â¢ The OSD as a whole is considered a DoD Component. By law, the Secretary and Deputy Secretary of Defense are the âheadâ of OSD.
The Big Dipper is an asterism that makes up part of the constellation of Ursa Major (The Big Bear). It is seen here at the lower left of the image. The Little Dipper, part of the constellation of Ursa Minor (The Little Bear), is seen at the upper right. Polaris, the North Star, is at the end of the handle of the Little Dipper.
In practice, the term pole star usually refers to Polaris, which is the current northern pole star, also known as the North Star.The south celestial pole lacks a bright star like Polaris to mark its position.he closest bright star to the north celestial pole is Polaris. At magnitude 1.97 (variable), it is the brightest star in the Ursa Minor constellation (at the end of the handle of the Little Dipper asterism).
