Concept:A constellation is a group of stars that forms a recognizable pattern in the night sky.
Explanation:Constellations are human-defined groupings based on apparent positions as seen from Earth.
The stars within a constellation are not physically close; they may be at very different distances from us.
Thus, they are
not necessarily equidistant from the Earth.
This matches the definition in option B.
Famous constellations include Ursa Major (Big Dipper), Orion, Cassiopeia, and Leo Major.
Option A is incorrect because stars in a constellation are not equidistant.
Option C is wrong because constellations are mostly stars, not planets.
Option D is incorrect because constellations include only stars, not planets or satellites.
Answer:Option B: A particular pattern of stars that may not be equidistant from the earth in the sky.
