What is the earthly planet?

Earth planet is a term used to describe four planets in the solar system that is closest to the sun, mercury, Venus, Earth and Mars. These four planets are mainly made of rock and have solid surfaces. The word earthly is derived from the Latin word terra , which means land or land.

In addition to rocky, solid composition, earthly planets share certain similar properties:

• are near the sun.
• either have no months or several months.
• Everyone has weak magnetic fields.
• They all have closely distributed orbit.
• none of the planets has rings around him. Gas planets are much larger than earthly planets and are mainly composed of gas and liquid.

  in Contrast on earthly planets, some characteristics of gas planets are:

  • are all away from the sun.
  • have more months.
  • Everyone has strong magnetic fields.
  • There is a greater distance between the orbit.
  • Everyone has some form of rings orbiting every planet.

  Mercury is the smallest earthly planet and is the nearest planet in the solar system in the sun. The planet's surface temperature ranges from 840 ° Fahrenheit (450 ° C) to a possible minimum of -275 ° Fahrenheit (-170 ° Celsius). Mercury was named after the Roman god Mercury, which was considered a rapid messenger between the gods, because it seemed that the planet was moving so quickly in the sky.

  Venus is the second planet from the Sun and its size is very similar to the size of the Earth. The Venus is surrounded by a heavy, dense, mostly composed of carbon dioxide. Carbon dioxide layer allows heat to enter the planet, but does not allow heat to leave, causing the greenhouse effect. The net result is that the high temperature of the Venus, which is 900 ° Fahrenheit (482 ° Celsius), is actually more than the temperature of mercury.

  Earth is the third planet from the Sun and is the only known planet to have life in space. Earth is the largest earthly planet and the fifth largest planet in the solar system. Like other earthly planets, the Earth surrounds the atmosphere. The country also has one month.

  Mars is the fourth planet from the Sun and the last earthly planet of the solar system. Mars was named after the Roman god of war and could be named for his red appearance. Mars is two months old, Phobos and Deimos, and is the only earthly planet different from the Earth that has months around him.

  Martian surface temperatures can be low -207 ° Fahrenheit (-133 ° Celsius) to 80 ° Fahrenheit (27 ° Celsius). Like Venus, Mars has an atmosphere consisting mainly of carbon dioxide. However, the greenhouse effect on Mars is much less than Venus. On July 31, 2008, US National Aviation Administration and Space Administration (NASA) announced that its Phoenix Mars Lander has identified water in sample mArian land.
