The number of moons that Mercury has is 0. Mercury is classified as a terrestrial planet. A day on Mercury is 58 days, 25 hours, and 30 minutes on Earth and a year in Mercury is 88 Earth days. The average temperature on Mercury can be 800-290 degrees Fahrenheit the reason for this is because the part of Mercury that hits the Sun gets really hot but the other part of Mercury gets really cold because the sun is not hitting it. Mercury is about 4.503 billion years old and is 0.39 astronomical units from the Sun.
