Here's why:
* Constellations are patterns: They're groupings of stars that appear close together from Earth but are actually spread out across vast distances.
* No defined boundaries: Constellations are not bounded areas in space. The stars within them are located at various distances from Earth.
Instead of miles, we can measure a constellation's size in degrees:
* Angular size: The apparent size of a constellation in the sky is measured in degrees.
* Orion's angular size: Orion covers approximately 1,000 square degrees of the sky. This means it's a relatively large constellation.
Important note: While we can measure the angular size of a constellation, it's impossible to express its true size in miles because the stars within it are at vastly different distances from Earth.
