Answer:
Option (3)
Explanation:
A constellation is usually defined as a collection of stars that appears in the sky forming a particular type of shape or pattern. They are located at a very large distance from one another. These constellations are often used in order to locate any astronomical objects in space.
These stars appearing in a constellation generally appears to be closer to one another in the night sky, but they are actually located at about many light years away from one another. Â
For example, in the Orion constellation, the stars appearing in the sky are about 25-30 light-years away from one another.
Thus, the correct answer is option (3).
