What Is a Light
... What is the nearest star to Earth? Our sun is the nearest star. It is about 150,000,000 km away. The next closest star to Earth is Proxima Centauri. Proxima Centauri is 40 trillion (40,000,000,000,000) kilometers from Earth. Such a large number is difficult to understand and use in calculations. For ...
