  1. Large semi-axle 149.598.023 km
  2. Distance to perihelion 147.095.000 km
  3. Distance to aphelion 152.100.000 km
  4. Average orbit speed 11,186 km/s
  5. Average radius approx. 6.371 km
  6. Inclination of the equator in orbit 7,155°
  7. Surface temperature 288 K 

And as you know this is the earth, the third planet from the Sun, a day lasts 23 hours, 56 minutes and 4 seconds. Okay, taking after us meant 24 hours, but it's not very scientifically correct. It is the only planet where life has been proven, where humans exist. The planet has a varied relief, being in the middle of the order of the planets. It has mountains, plains, meadows, hills, meadows, plateaus, water and land and millions of animal species, including man. The earth was formed 4.5 billion years ago. Life on earth in the first billion years of life, life was in the water, there were bacteria, and then, dinosaurs, animals, birds, fish, insects, etc. and people. 

And 3.5 billion years ago, its magnetic field stabilized. Theoretically we still have a long way to go, because the sun increases its brightness in the next 1.1 billion years by only 10%, a lot! The problem is after 3.5 billion years, when it will increase by 40%, then the carbon cycle accelerates, and then we will no longer exist.

The problem is after 3.5 billion years, when it will increase by 40%, then the carbon cycle accelerates, and then we will no longer exist. The average diameter is 12,742 kilometers. And, as we know, the Earth is bulging at the equator and flattened at the poles, so only with the eye can we say that it is spherical, but not physical. Earth is also a terrestrial planet, like Mercury and Venus, it has the same composition. Below you have some data:

  1. 0-60 km Lithosphere
  2. 0-35 km Bark
  3. 35-60 km Upper Mantaua
  4. 35-2890 km Mantaua
  5. 100-700 km Asthenosphere
  6. 2890-5100 km Outer core
  7. 5100-6378 km Inner core

When we talk about the atmosphere approx. 75% of its mass is in the first 11 km of the atmosphere, ie where the planes pass. The Earth's natural satellite is the Moon, and the highest peak on Earth is Everest Peak. When we talk about climate the easiest is to use the Köppen classification system, which divides the world into five zones: tropical wetland, arid desert, wetland at medium latitudes, continental climate zone and cold polar zone, which are then subdivided into May many more specific subtypes.
