Answer Starts

A galaxy is a vast collection of stars, dust and gases held together by the gravitational attraction between its components.

Most of the galaxies are either spiral or elliptical. Elliptical galaxies are very bright, while spiralgalaxies are usually much bigger.

• All galaxies are moving away from each other.

• Our Earth and the Sun belong to the Milky Way galaxy. Milky Way galaxy contains about 100 billion stars. The Indian name of the Milky Way galaxy is Akash Ganga.

Elliptical galaxies are made of old stars. They are the most massive galaxies containing trillions of stars. Irregular galaxies have no apparent structure or shape.
