Looking up at the night sky can fill you with awe as you sift through the tiny points of light. Some stars are more luminous than others because of their proximity to Earth and the closest stars to Earth will appear the brightest. In astronomy, brightness is measured in negatives. This means, the larger the number, the dimmer the object. For example, Earth’s moon has a magnitude of -12.6 and our Sun has a magnitude of -26.7. The farthest stars are not seen with the naked eye, but only seen wit ...read more
