Jupiter is the fifth planet from the Sun and the largest in the Solar System.A gas giant, Jupiter's mass is more than two and a half times that of all the other planets in the Solar System combined and slightly less than one one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm) with an orbital period of 11.86 years.
A wiki ( / ˈwɪki / ⓘ WI-kee) is a form of online hypertext publication that is collaboratively edited and managed by its audience directly through a web browser.

Science is a strict systematic discipline that builds and organizes knowledge in the form of testable hypotheses and predictions about the world. Modern science is typically divided into three major branches: the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and ...
An operating system is difficult to define,[7]but has been called "the layer of softwarethat manages a computer's resources for its users and their applications".[8] Operating systems include the software that is always running, called a kernel—but can include other software as well. [7][9]The two other types of programs that can run on a ...

DNA profiling was developed in 1984 by British geneticist Sir Alec Jeffreys, and first used in forensic science to convict Colin Pitchfork in the 1988 Enderby murders case. [167] The development of forensic science and the ability to now obtain genetic matching on minute samples of blood, skin, saliva, or hair has led to re-examining many cases.
The planet's density is the second highest in the Solar System at 5.427 g/cm 3, only slightly less than Earth's density of 5.515 g/cm 3. If the effect of gravitational compression were to be factored out from both planets, the materials of which Mercury is made would be denser than those of Earth, with an uncompressed density of 5.3 g/cm 3 ...
