Sun

The Sun is a bright, white square in the sky that first appeared in Update 0.7.3. It only appears during the day, which in Minecraft lasts for 10 minutes of real time. During the day, the sun emits a light level of 15 worldwide.

Trivia

 * The Sun will become larger during sunset and sunrise.
 * Before Update 0.8.0, if the player went to the edge of the world during night in third person mode, the sun was at the bottom of the world.
 * Also, if the player dug to the Void at night, the they could see the sun below the themselves and vice versa during the day.
 * After Update 0.10.0, the size of the sun was increased.
 * When beautiful skies is turned off, the sun is not visible. This is the same with the Moon.
 * After Update 0.12.1, the Skeletons' and Zombies' AI was improved to avoid direct contact with the sunlight whilst seeking a nearby area with a solid block above or any water block to avoid burning.
 * If a skeleton or a zombie cannot locate a tree or a water source, e.g. in a desert, it will stand in its position until it spots a player within a 15 block radius.
