How far away are the stars?

Out there in space, blazing just a scant 150 million kilometers away lies the brightest and most massive object in our Solar System: the Sun. Shining hundreds of thousands of times as bright in Earth’s skies as the next brightest object, the full Moon, the Sun is unique among Solar System objects for producing its own visible light, rather than only appearing illuminated because of reflected light. However, the thousands upon thousands of stars visible in the night sky are all also self-luminous, distinguishing themselves from the planets and other Solar System objects in that regard. Unlike the planets, Sun, and Moon, the stars appear to remain fixed in their position over time: not only from night-to-night but also throughout the year and even from year-to-year. Compared to the objects in our own Solar System, the stars must be incredibly far away. Furthermore, in order to be seen from such a great distance, they must be incredibly bright. <a href="https://medium.com/starts-with-a-bang/how-far-away-are-the-stars-126fb67c56bc">Visit Now</a>
