- The sun of galaxy X has a diameter of about 796,000 mi with a maximum distance from Planet X's surface of about 78,700,000 mi. Planet X's moon has a diameter of 2,731 mi. For a total solar eclipse to occur, the moon must pass between the sun and Planet X. The moon must also be close enough to Planet X for the moon's umbra (shadow) to reach the surface of Planet X. The maximum distance that the moon can be from Planet X and still have a total solar eclipse occur i (Round to the nearest thousand as needed )(a) The distance to a star is approximately 7.80 1018 m. If this star were to burn out today, in how many years would we see it disappear? years (b) How long does it take for sunlight to reach Saturn?Calculate the apparent magnitude of the Sun.
