Characteristics of a Galaxy

A Galaxy is a large group of stars, gas, and

dust held tighter by

gravity.

Page 2: Characteristics of a Galaxy A Galaxy is a large group of stars, gas, and dust held tighter by gravity.

Types of Galaxies

Spiral Galaxy*Have spiral areas that

wind outward from inner regions.

*The arms are made up of stars and dust.

*Milky Way (our universe is a spiral).

*Brightest stars.*Most common galaxy.

Types of Galaxies

Elliptical Galaxy*Shaped like large

three –dimensional ellipses.

*Oldest stars.

Types of Galaxies

Irregular Galaxy*Have many shapes*Smaller than other

types of galaxies.*Newest stars.
