The Uranus Orbiter and Probe is an orbiter mission concept to study Uranus and its moons. [1] The orbiter would also deploy an atmospheric probe to characterize Uranus's atmosphere . The concept is being developed as a potential large strategic science mission for NASA .
The pronunciation of the name Uranus preferred among astronomers is / ˈ jʊər ə n ə s / YOOR-ə-nəs, [1] with the long "u" of English and stress on the first syllable as in Latin Uranus, in contrast to / j ʊ ˈ r eɪ n ə s / yoo-RAY-nəs, with stress on the second syllable and a long a, though both are considered acceptable.

In particular, he had introduced the Karlspfund ("Charles pound") as the basic unit of coinage and trade which, however, weighed only 8 ounces. In order to prevent a further reduction in the weight of a pound, a sign, the mark , was now stamped on the new weights.
The Earth's crust from the surface to 25 km (15 mi) down is calculated to contain 10 17 kg (2 × 10 17 lb) of uranium while the oceans may contain 10 13 kg (2 × 10 13 lb). [11] The concentration of uranium in soil ranges from 0.7 to 11 parts per million (up to 15 parts per million in farmland soil due to use of phosphate fertilizers ), [ 63 ...
Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on ...
This isotope mix causes the atomic weight of ordinary Earthly boron samples to be expected to fall within the interval 10.806 to 10.821. and this interval is the standard atomic weight. Boron samples from unusual sources, particularly non-terrestrial sources, might have measured atomic weights that fall outside this range.
Umbriel (/ ˈ ʌ m b r i ə l /) is the third-largest moon of Uranus.It was discovered on October 24, 1851, by William Lassell at the same time as neighboring moon Ariel.It was named after a character in Alexander Pope's 1712 poem The Rape of the Lock.
