Earth is the third planet from the Sun and the only astronomical object known to harbor life.This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water.
Blue light is scattered more than other wavelengths by the gases in the atmosphere, surrounding Earth in a visibly blue layer at the stratosphere, above the clouds of the troposphere, when seen from space on board the ISS at an altitude of 335 km (208 mi) (the Moon is visible as a crescent in the far background).
A wide variety of sources [5] [6] [7] define LEO in terms of altitude.The altitude of an object in an elliptic orbit can vary significantly along the orbit. Even for circular orbits, the altitude above ground can vary by as much as 30 km (19 mi) (especially for polar orbits) due to the oblateness of Earth's spheroid figure and local topography.
The original 2013 map by Ken Myers, with the interior of the circle inverted. A Valeriepieris circle [1] [2] [3] is a figure drawn on the Earth's surface such that the majority of the human population lives within its interior.
Earth's rotation imaged by Deep Space Climate Observatory, showing tilt. Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space.
The Big Bang theory, which explains the Evolution of the Universe from a hot and dense state, is widely accepted by physicists.. In astronomy, cosmogony is the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the Solar System, or the Earth–Moon system.
Tsk, tsk, tsk. Embarrassing. People in the comments section were totally judging. "He’s giving Cristina Yang in Grey's Anatomy when she screams SOMEBODY SEDATE MEEEEE," quipped one commenter ...
Asia (/ ˈ eɪ ʒ ə / ⓘ AY-zhə, UK also / ˈ eɪ ʃ ə / AY-shə) is the largest continent [note 1] [10] [11] in the world by both land area and population. [11] It covers an area of more than 44 million square kilometres, [note 2] about 30% of Earth's total land area and 8% of Earth's total surface area.
