Beautiful Earth and Moon - Space Engine

Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is enabled by Earth being a water world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering 70.8% of Earth's surface. The remaining 29.2% of Earth's surface is land, most of which is located in the form of continental landmasses within one hemisphere, Earth's land hemisphere. Most of Earth's land is somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined. Earth's land is part of Earth's crust, consisting of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation.

The Moon is Earth's only natural satellite. It orbits around Earth at an average distance of 384400 km (238900 mi; 1.28 ls), or about 30 times Earth's diameter. The Moon faces Earth always with its near side by having a rotation period that equals its orbital period, resulting from being tidally locked to Earth. This period is in relation to the Sun 29.5 days long and visible as the cycle of the lunar phases. For Earth, the Moon has been aside from the Sun the most influential celestial object, particularly with its gravitational influence it has been the main driver of Earth's tides.
