What is the Earth like? (Send a picture)

Details and pictures of what the Earth looks like are as follows:

Earth is one of the eight planets in the solar system. It is the third planet in order from closest to the sun and is also the third planet in the solar system. The largest Earth-like planet in terms of diameter, mass and density, it is 150 million kilometers away from the sun. The earth rotates from west to east while revolving around the sun. It is 4.0 to 4.6 billion years old. It has a natural satellite, the moon, and the two form a celestial body system, the earth-moon system. Originated from the primitive solar nebula 4.6 billion years ago.

The earth has an equatorial radius of 6378.137 kilometers, a polar radius of 6356.752 kilometers, an average radius of about 6371 kilometers, and an equatorial circumference of about 40076 kilometers. It is an irregular elliptical sphere with slightly flattened poles and slightly bulging equator. The earth's surface area is 510 million square kilometers, of which 71% is ocean and 29% is land. The earth appears blue when viewed from space.

The interior of the Earth has core, mantle, and shell structures, and the exterior of the Earth has the hydrosphere, atmosphere, and magnetic field. The Earth is currently the only celestial body known to contain life, and is home to millions of species of creatures, including humans.

Cavendish believed that the mass of the earth is about 5.96×10^24 kilograms. The equatorial radius of the earth is ra=6378137m≈6378km, the polar radius rb=6356752m≈6357km, and the oblateness e=1/298.257. Neglect The Earth is aspherically symmetrical, with an average radius of r=6371km. The value of gravity acceleration at a certain sea level at the equator is ga=9.780m/s^2, the value of gravity acceleration at a certain sea level at the North Pole is gb=9.832m/s^2, and the global standard value of gravity acceleration is g=9.807m /s^2, the Earth’s rotation period is 23 hours, 56 minutes and 4 seconds (sidereal day), that is, T=8.616×10^4s.
