Polaris It is a star almost 50 times larger than the sun and is a Cepheid variable star, meaning that its brightness varies in a regular pattern. This property allowed astronomers to calculate the distance to other galaxies and make important discoveries about the structure and expansion of the universe.
In short, Polaris is the main star of the Big Dipper and is of great importance for navigation and astronomy. Its alignment with the Earth’s axis of rotation makes it a constant reference point in the night sky, making it very useful as a guide for travelers and explorers.
