Mimas

By: Cheyenne Erickson

Introduction

Mimas is one of Saturn's moon. Mimas is also known as 'Saturn's "Death Star" because it supposedly looks similar to the Death Star in Star Wars.

Fun Facts

Here are some fun facts about Mimas. Mimas' full journey around Saturn is 22 hours and 37 minutes. It rotates on its axis at the same rate it circles its planet which is under an Earth Day. Mimas faces towards Saturn at all times. Mimas is the most heavily cratered surface in the Solar System. Its face is smaller than 250 miles across. Mimas contains small amounts of rock along with the water-ice, which is most of the moon. In conclusion, those were some fun facts about Mimas.

Appearance

Here is some facts about Mimas' appearance. Mimas travels in an Elliptical Orbit meaning out of round, which has an average of 125,000 miles. It is 242 miles or 390 kilometers across. Mimas created the Cassini Division between rings A and B, which is 2,980 miles or 4,800 kilometers. Mimas is the closest to Saturn than the rest of the moons. To conclude, those were some facts about Mimas' appearance.

Discovery

Here is some information about the discovery of Mimas. Mimas was discovered by the English Astronomer, Sir William Hershel. Sir William Hershel discovered Mimas on September 17, 1789. Mimas was named after a Greek God by the discoverers son, John. In conclusion, that was some information about the discovery of Mimas.

Other Information

Here is some other information about Mimas. The Axis of the semi-major orbit is 115,289 miles or 185,289 kilometers. The orbit eccentricity is 0.01%. The mean radius is 123 miles or 189 kilometers. The surface area of Mimas is 190,599 miles2 or 493,648 kilometers2. The escape velocity is 0.099 mph (miles per hour) or 0.159 kph (kilometers per hour). Mimas has a solid temperature of 209 C or -344 F. The mass of Mimas is 3.80e+19 kilograms. The equatorial radius is -1%. The mean density is 1.17 grams/centimeters3. The rotational period or one day on Mimas is 0.942422 days. The mean orbit velocity is 1.32 kilometers/seconds. The orbit eccentricity is 0.0202. The orbit inclination is 153 . The essential velocity of Mimas is 161 kilometers/seconds. The visual geography albedo is 0.5. The magnitude or velocity is 12.9. The surface temperature of Mimas is -200 C. In conclusion, those were some other facts about Mimas.

Herschel Carters & Other Craters

Here are some facts about the Herschel crater and the other craters. The Herschel crater is a 3rd of the side of the entire moon itself. The Herschel Carter on Mimas is 81 miles or 130 kilometers wide and 3 miles or 5 kilometers high. The shock wave of the Herschel Crater can be shown by the cracks all around the moon. On Mimas there are overlapping depressions covering the surface. Several of the craters reach 25 miles or 30 kilometers in diameter. In the South Pole, craters are smaller then 12.4 miles or 20 kilometers across. In conclusion, those were some facts about the Herschel crater and the other craters on Mimas.
