Mercury holds the reward for the smallest and most innermost planet. It is about 3,030 miles in diameter, and its distance from the Sun can range from 29 million miles to 43 million miles.  Although Mercury is the closest planet to the sun, its surface can still be extremely cold. During the day, the temperature can reach a scorching 840°F, but at night, temperatures can get as low as -275°F. Speaking about day, one day on Mercury (the time it takes for it to spin once with respect to the stars) takes 59 Earth days. One day-night cycle on Mercury takes 176 Earth days.  A year on Mercury is equivalent to 88 Earth days.
