The planet has a mass less than 0.3 Jupiter masses (90 Earth masses) and a radius nearly equal to that of Jupiter, just 4% smaller, or the same as 10.7 Earth radii. [1] It is still enshrouded in an hydrogen envelope, and will shed its outer layers during its evolution, [2] becoming either a sub-Neptune, super-Earth or a sub-Saturn.
Drinking water has been distilled from seawater since at least about AD 200, when the process was clearly described by Alexander of Aphrodisias. [1] Its history predates this, as a passage in Aristotle's Meteorologica refers to the distillation of water. [2]
In 1959–1961 Great Britain Atomic Energy Authority produced 125 g of 99.9% pure protactinium at a cost of $ 500 000, giving the cost of 4 000 000 USD per kg. [44] Periodic Table of Elements at Los Alamos National Laboratory website at one point listed protactinium-231 as available from Oak Ridge National Laboratory at a price of 280 000 USD/kg.
The value of G times the mass of an object, called the standard gravitational parameter, is known for the Sun and several planets to a much higher accuracy than G alone. [13] As a result, the solar mass is used as the standard mass in the astronomical system of units .
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
The 12.7×108mm cartridge is a 12.7 mm heavy machine gun and anti-materiel rifle cartridge used by the former Soviet Union and Warsaw Pact countries, including Russia, China, Iran, North Korea, and many others.
