a)Look toward the south-southeast to find Sirius in winter in the Northern Hemisphere.

Locate the constellation of Orion, particularly the three stars of Orion’s belt. Focus in on the leftmost star of the belt.

Hold your right arm out straight with the right edge of your fist adjacent to where you see the leftmost star. Rotate your fist diagonally so it continues the left-and-downward slant of the belt. According to Space.com, one fist equals about 10 degrees of sky when held out at arm’s length.

Place your left fist next to your right, also diagonally. Sirius should be at the left edge of your left fist.

The North Star, also known as Polaris, is often used by campers to help them find their way when lost. You may also just want to find the North Star for fun if you're into star gazing. You can rely on constellations in the night sky to find the North Star. As most constellations you'll need to use are in the northern sky, you'll need to figure out which direction is north first. If you do not have a compass, you can rely on signs from nature to figure out whether or not you're facing north.
