Mimas / ˈ m aɪ m ə s /, also designated Saturn I, is a moon of Saturn which was discovered in 1789 by William Herschel. It is named after Mimas, a son of Gaia in Greek mythology.. With a diameter of 396 kilometres (246 mi), it is the smallest astronomical body that is known to still be rounded in shape because of self-gravitation.However, Mimas is not actually in hydrostatic …

Dec 19, 2019 · Mimas was discovered on Sept. 17, 1789 by English astronomer William Herschel, using his 40-foot reflector telescope. Ground-based astronomers could only see Mimas as little more than a dot until Voyagers I and II imaged it in 1980. The Cassini spacecraft made several close approaches and provided detailed images of Mimas. Overview

Uranus is the seventh planet from the Sun.Its name is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares (), grandfather of Zeus and father of Cronus ().It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.Uranus is similar in composition to Neptune, and both have bulk …

Mit Beginn der 1770er Jahre wandte sich Wilhelm Herschel mehr und mehr der Astronomie zu. Durch das Studium der mathematischen Musiktheorie angeregt befasste er sich mit Mathematik sowie dem Bau und Verkauf astronomischer Instrumente. Mit dem Studium astronomischer Werke wuchs sein Interesse an der Astronomie, die sich für ihn nicht nur auf die Beobachtung …

Having a diameter of only 250 miles (400 kilometres), Mimas is the smallest moon in the solar system that is still able to mold itself into a sphere under its own gravity. However, it’s not completely a sphere.

Oct 09, 2008 · William Herschel's son John Herschel suggested the name in his 1847 publication Results of Astronomical Observation made at the Cape of Good Hope, in which he suggested names for the first seven Saturnian moons discovered.

The resemblance of Saturn’s moon Mimas to an iconic moon-shaped fictional space station is largely the fault of a giant impact crater that covers a third of its diameter. The crater measures 130 km across with a 5 km surrounding walls is known as the Herschel Crater, after William Herschel who spotted the moon in 1789.

Hubble views extraordinary multi-tailed asteroid P/2013 P5.. One mystery of the asteroid belt is the relative rarity of V-type, or basaltic asteroids. Theories of asteroid formation predict that objects the size of Vesta or larger should form crusts and mantles, which would be composed mainly of basaltic rock, resulting in more than half of all asteroids being composed either of …
