Artist's impression of the early Solar System's planetary disk The oldest material found in the Solar System is dated to 4. In theory, a solar nebula partitions a volume out of a molecular cloud by gravitational collapse, which begins to spin and flatten into a circumstellar diskand then the planets grow out of that disk with the Sun. A nebula contains gas, ice grains, and dust including primordial nuclides. According to nebular theoryplanet earth singles formed by accretionwith the primordial Earth being estimated as likely taking anywhere from 70 to million years to form.

The first continental crustwhich was more felsic in composition, formed by the partial melting of this mafic crust. The presence of grains of the mineral zircon of Hadean age in Eoarchean sedimentary rocks suggests that at least some felsic planet earth singles existed as early as 4. The two models and the data that support them can be reconciled by large-scale recycling of the continental crustparticularly during the early stages of Here history.

Over the period of hundreds of millions of years, tectonic forces have caused areas of continental planet earth singles to group together to form supercontinents that have subsequently broken apart. At approximately Ma, one of the earliest known supercontinents, Rodiniabegan to break apart.

The continents later recombined to form Pannotia at — Ma, then finally Pangaeawhich also began to break apart at Ma.]

All of these seven planets could have liquid water -- key to life as we know it -- under the right atmospheric conditions, but the chances are highest with three of the plants which are located in the habitable zone, according to the researchers. At about 40 light-years trillion miles from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets. Assisted by several ground-based telescopes, including the European Southern Observatory's Very Large Telescope, NASA's Spitzer space telescope confirmed the existence of two of these planets and discovered five additional ones, increasing the number of known planets in the system to seven. Using Spitzer data, the team precisely measured the sizes of the seven planets and developed first estimates of the masses of six of them, allowing their density to be estimated.
