Hang Ten

The circle of sky is divided into 360 degrees. The “hang ten” sign shows about a 20-degree distance when holding your hand out at arm’s length. This is roughly the length of the Big Dipper. A closed fist measures about 10 degrees, and one finger equals one degree. At night, identify a major constellation, like Orion or Ursa Major.
