A Sol is a day on Mars. A Earth day is twenty four hours but a Mars day is twenty four hours thirty nine minutes and thirty five seconds. Since the length of their days are longer that means that their year is longer too. A Earth year is three hundred and sixty five days and a Mars year is six hundred eighty seven days. The formation of the days means the lengthening of the seasons and also seasonal growths. The lengthening of the seasons means that plants or life forms have a different growth pattern than we do on earth. On one clear sol the output averaged seven hundred watt-hours. On a summer day on mars the day would be 95 degrees F (fahrenheit) and then fall to -130 degrees F at night.
