Earth's average orbital distance is about 150 million km (93 million mi), which is the basis for the astronomical unit (AU) and is equal to roughly 8.3 light minutes or 380 times Earth's distance to the Moon. Earth orbits the Sun every 365.2564 mean solar days, or one sidereal year. With an apparent movement of the Sun in Earth's sky at a rate ...

The history of life on Earth traces the processes by which living and fossil organisms evolved, from the earliest emergence of life to present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. The similarities among all known present-day species indicate that they have diverged through the process of ...
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine-and-a-half times that of Earth. [26] [27] It has only one-eighth the average density of Earth, but is over 95 times more massive.

[1] The term came into common usage during the 16th century, when it was used to refer to groups of various kinds, including those characterized by close kinship relations. [2]
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers ( stratigraphy ). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
Homer considers her a physical distinct existence not clearly conceived in anthropomorphic form. Gaia does not seem to have any personal activity. In Iliad Alpheia beats with her hands the bountiful ("polyphorbos") earth, but she calls Hades and Persephone to avenge her against her son In the poems
Early modern human. Early modern human ( EMH ), or anatomically modern human ( AMH ), [1] are terms used to distinguish Homo sapiens (the only extant Hominina species) that are anatomically consistent with the range of phenotypes seen in contemporary humans, from extinct archaic human species. This distinction is useful especially for times and ...
