Answers
Answer:
There are billions of galaxies in the Universe. There are not many galaxies, which are visible to the naked eyes. It is a collection of only a few stars. Stars in the constellation are arranged in patterns resembling human beings or some animals.

Constellation
A cluster or group of fixed stars, or division of the heavens, designated in most cases by the name of some animal, or of some mythologial personage, within whose imaginary outline, as traced upon the heavens, the group is included.
Galaxy
very large collection of stars comparable in size to the Milky Way system, held together by gravitational force and separated from other such star systems by large distances of mostly empty space. Galaxies vary widely in shape and size, the most common nearby galaxies being over 70,000 light years in diameter and separated from each other by even larger distances. The number of stars in one galaxy varies, and may extend into the hundreds of billions.
Main difference
The main difference between Constellation and Galaxy is that the Constellation is a one of the 88 divisions of the celestial sphere, defined by the IAU, many of which derive from traditional asterisms and Galaxy is a astronomical structure.
