The constellation Ursa Minor, also known as the Little Bear, sparkling in the night sky.

Ursa Minor

Ursa Minor, which means "Lesser Bear" in Latin, is a special group of stars in the night sky. It is also called the Little Bear or the Little Dipper because its shape looks like a small spoon.

The most important star in Ursa Minor is Polaris, also called the north pole star. This bright star helps people find the north direction. It was very useful for sailors long ago.

Ursa Minor is one of the 88 modern constellations and has been known since ancient times. The Greek astronomer Ptolemy listed it many years ago.

People in different cultures had their own names and stories for these stars. They were important for navigation and telling stories around the world. Ursa Minor is next to other star groups like Draco and Cepheus.

Because Ursa Minor is far in the northern sky, only people in the northern part of the world can see it. Its brightest stars form a shape that looks like a little dipper, just like a bigger group of stars called the Big Dipper.
