Ariel: Uranus Brightest Moon

From its discovery in the depths of space, to what makes it special in terms of composition, and more! Allow us to show you Ariel Uranus Brightest Moon.

10. The Discovery of Ariel
In terms of its finding, Ariel was discovered on October 24, 1851 by William Lassell, it is named for a sky spirit in an Alexander Pope's story and Shakespeare's The Tempest. Which is not too uncommon given the power that literature and mythology have in regards to naming things like this.
Both Ariel and the slightly larger Uranian satellite Umbriel were discovered by William Lassell on the same day believe it or not.
9. Its Surface
All of Uranus' larger moons, including Ariel, are thought to consist mostly of roughly equal amounts of water ice and silicate rock. Carbon dioxide has also been detected on Ariel. Which is important in helping determine various things about the moon itself.
8. Rotations and Orbits
Among Uranus's five major moons, Ariel is the second closest to the planet, orbiting at the distance of about 190,000 km, or over 118,000 miles.
7. Observation and Exploration
The only close-up images of Ariel were obtained by the Voyager 2 probe (one of the most important scientific tools in the history of the space program), which photographed the moon during its flyby of Uranus in January 1986.
6. Atmosphere
Despite there being carbon dioxide on the moon of Ariel in some capacity, there is no detectable atmosphere or magnetosphere that we can find.
5. Surface Temperature
Measurements have shown that Ariel's surface temperature rises and falls quickly with the coming and going of sunlight, without a "thermal inertia" lag. That supports the picture of a porous surface, which would tend to insulate the moon and keep the subsurface from heating up. This texture could be the result of eons of micrometeorite strikes tilling the soil.
