The Terrestrial Planets of the Milky Way

The Terrestrial Planets of the Milky Way

Aterrestrial planet is a period utilised to recount the four planets in the solar system that are nearest to the sun, Mercury, Venus, soil, and Mars. These four planets are created mainly of rock and have solid surfaces. The phrase terrestrial is drawn from from the Latin phrase terra, significance ground or soil.

Besides a rocky, solid composition, the terrestrial satellites share certain alike characteristics:

They are close to the sun.

They either have no moons or couple of moons.

They all have feeble magnetic fields.

They all have closely positioned orbits.

None of the satellites have rings round them.

The four other foremost planets, Jupiter, Saturn, Neptune, and Uranus, in the solar scheme are referred to as gas planets or Jovian satellites, after the planet Jupiter which is the largest planet in the solar system. The gas satellites are much larger than the terrestrial satellites and are created mostly of gas and liquid.

In compare to the terrestrial satellites, some characteristics of the gas satellites are:

They are all farther away from the sun.

They have multiple moons.

They all possess powerful magnetic fields.

There is a greater distances between orbits.

They all have some pattern of rings orbiting each planet.

Mercury is the smallest terrestrial planet and is the closest planet in the solar scheme to the Sun. The surface temperature of the planet varieties from a high of 840° Fahrenheit (450° Celsius) to likely low of -275° Fahrenheit (-170° Celsius). Mercury was named after the Roman god Mercury, who was considered to be the speedy messenger between the gods, because the planet seemed to move so rapidly in the sky. (Battaglia, 2005)

Venus is the second planet from the Sun and its size is very alike to that of the Earth. Venus is enclosed by a heavy, dense atmosphere mostly composed of carbon dioxide. The carbon dioxide level allows heat to go in the planet but does not permit heat to leave, initating a greenhouse effect. The net result of this is that the high temperature of Venus, which is 900° Fahrenheit (482° Celsius), is actually larger than that of Mercury.

Earth is the third planet from the Sun and is the only renowned planet to harbor life in the universe. Earth is the biggest terrestrial planet and the fifth biggest planet in the solar system. Like the other terrestrial satellites, soil has an air surrounding it. Earth furthermore has one moon.

Mars is the fourth planet from the sun and the last terrestrial planet of the solar system. Mars was entitled after the Roman god of conflict and may have been so entitled because of its red appearance. Mars has two moons, Phobos and Deimos, and is the only terrestrial planet other than the soil to have moons in orbit around it. The terrestrial satellites make up the inward solar system. They pattern a associated assembly of rocky worlds that are very distinct from the gas satellites of the outside ...
