The Earth is also called the Blue Planet, "Planet Earth", and "Terra". The Earth is home to millions of species of plants and animals, including humans. Earth is the only planet in the galaxy known to support life. Earth has many places that are suitable for humans to live in, although some areas of the planet can be very dangerous, too.
Earth, has been referred to as the Blue Planet due to the abundant water on its surface and/or the atmospheric hue; Neptune, a planet in the solar system that appears blue and can therefore be called "Blue planet" The Blue Planet, a BBC documentary series narrated by David Attenborough; Blue Planet II, a sequel to the documentary
Earth orbits the Sun, making Earth the third-closest planet to the Sun and part of the inner Solar System. 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 .
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
Earth is a pale blue dot, rather than dark blue, because white light reflected by clouds combines with the scattered blue light. [ 23 ] Earth's reflectance spectrum from the far-ultraviolet to the near-infrared is unlike that of any other observed planet and is partially due to the presence of life on Earth. [ 23 ]
The planet’s equivalent of the Sun, called Gliese 12, is a cool red dwarf located in constellation Pisces. The star is only about 27% of the Sun’s size, with about 60% of the Sun’s surface ...
A planet in the Solar System that have orbits smaller than the asteroid belt. [nb 2] Mercury, Venus, Earth, Mars: Outer planet: A planet in the Solar System beyond the asteroid belt, and hence refers to the gas giants. Jupiter, Saturn, Uranus and Neptune Pulsar planet: A planet that orbits a pulsar or a rapidly rotating neutron star. PSR B1257 ...
We also see the Rayleigh effect at play in: -Sunsets where the sky is red.Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow ...
