Question

Both galaxies and constellations are groups of stars. Give two differences between them.
​

Answer 1

Answer:

Galaxies may have millions or billions of stars. The most important difference between the two: galaxy is a scientific phenomenon while constellations are just works of art intended to help people to easily locate different sets of stars on the sky.

Answer 2

Constellation is a group of stars that form a specific shape like Orion, etc. and it contains only stars or nebulae. On the other hand, galaxy does not form any particular shape and there are planets, comets, asteroids, meteoroids, etc, which are not present in constellations
