Earth
Earth
is one of the 8 planets of our solar system. It is the third closest
planet to the Sun.
Description
of our planet:
Size:
The planet Earth is a relatively small planet for our solar
system with a mass of 5.9736×1024 kg and a diameter of
12,756.3 km.
Orbital Characteristics:
The planet Earth obits the Sun at an average speed of 29.78 km/s.
At this speed it takes this planet 365.2 days to complete its
revolution around the Sun. A day on Earth lasts 24 hours.
Brightness:

visual magnitude of -3.86 V(1,0) and an irradiance of 1367.6 W/m2.
Atmosphere:
Earth has a relatively thick atmosphere with an average density
of 5,515 kg/m3 and a mean pressure of 1014 mb. It's
atmosphere is composed of the elements 78.084% Nitrogen (N2),
20.946% Oxygen (O2), and other trace elements.
The mean temperature of Earth is 15 degrees Celsius.
Moons:
Earth has 1 moon. It is usually simply called "the Moon"
but it is sometimes referred to by its Latin name "Luna".
