Achernar, the ninth-brightest star in the night sky, is estimated to be around 58 million years old. This makes it a relatively young star compared to others in the galaxy. Its high rotational velocity causes it to be slightly flattened at the poles.
The size of a galaxy refers to its physical dimensions, typically measured in terms of its diameter or radius. Larger galaxies can contain billions to trillions of stars, while smaller galaxies may have fewer stars. Galaxy size can also provide clues about its age, structure, and evolutionary history.
