Is what you see the way it is?

Constellations:

• Leo
  
  This is supposed to be a lion. You can see it in late spring.

• Orion
  

  This is a great hunter. You can see him in winter.

• Ursa Major (the Big Dipper)
  
  This is (part of) a bear. The two stars at the end point to the North Star.

Two dimensions vs. three dimensions:

Really, the stars are different (big) distances away.

We can imagine the stars located on a celestial sphere.
"Distances" on the celestial are measured as angles.

The unit of angular measurement is usually the degree. A full circle is 360 degrees. One degree is divided into 60 arc minutes. One arc minute is divided into 60 arc seconds.
