Explanation is in a file
The Sun is by far the brightest object in the sky, with an apparent magnitude of -26.74, which is about 13 billion times brighter than the next brightest star (Sirius, which has an apparent magnitude of -1.46). The mean distance of the Sun to Earth is approximately 1 astronomical unit or AU (150,000,000 km/93,000,000 mi), though this changes due to variations in Earth’s orbit.
