The Four Terrestrial Planets
A planet consists of a solid body that revolves around a star and shines by reflected light. The sun is the only star known to have planets, although certain other stars have companions that may be planets. The sun, nine known major planets, in order of increasing distance from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The planets are divided into two groups according to their size and structure.
In our solar system, the terrestrial planets are the four planets closest to the Sun, namely, Mercury, Venus, Earth and Mars. The majority composition of these solar system planets is silicate rocks and iron. The small, rocky, terrestrial planets show similarities and differences

Earth is the planet that we live on. The Earth is the third planet away from the sun (Mercury and Venus are nearer) and is the fifth largest planet in the solar system. Earth is the only planet which is suited to life of any kind. It is usually said that the Earth is shaped like a ball but slightly bulges and flattened areas, which give it a slightly irregular shape. The planet is surrounded by an atmosphere. The oceans make up four fifths of the Earth’s surface. The land area consists of four large masses which are divided into seven contents, smaller masses and …show more content…
Magnetic field is a vector quantity defined by the force exerted on a given object at each point in a particular region. Venus’ magnetic field is much weaker compared to the magnetic field of Earth. The Earth’s magnetic field is generated internally, the result created by the planetary core and convection from the same area. Conversely, Venus’ magnetic field is created by the interaction of the ionosphere and the solar wind. Similarly to Earth, Venus appears to possess a liquid core that rotates like the Earth. However, Venus cannot transfer heat via convection due to the fact that the surface is encrusted by volcanic
Uranus is the only giant planet whose equator is nearly at right angles to its orbit and has 5 large moons and 22 smaller moons. It is, also, the only planet in our solar system to spin on its side. Uranus
Pluto has a crust believed to be composed mostly of water ice, with a relatively thin layer of nitrogen ice mixed with small fractions of methane and carbon. However, there is no particular scientific reason why this should exclude Pluto from being classified as a planet. It is just as reasonable to claim that all planets must have rocky surfaces, like the terrestrial planets: then Jupiter, Saturn, Uranus and Neptune would have to classified as something other than “planets” (perhaps they would be minor planets?). Alternatively, it could be declared that all
Earth is said to be the feminine element. It is perceived to be nurturing, stable, and full of endurance. The planet itself is a ball of life in which one is
Then red dwarf star that was discovered by Michal Gillion and his team with the spencer telescope. Once they discovered this star that is a lot small and colder than our sun, it allowed them to get a vision of the seven planets. The star is about 40 light years away. There are not 3 or four planets but there are 7 earth like planets.
The reading on terrestrial planets from chapter 6 provides readers with a little insight on the similarities and differences between the planets. These planets include Earth, Venus, Mercury, and Mars. Although these planets have very different properties, they are connected due to their history. There are scientific laws that help people understand, compare, and contrast these planets, such as gravity, chemical composition, and temperature.
In the Solar System there is nine planets total counting Pluto and eight not counting pluto. Named after the Greek god of the underworld Pluto is the ninth of the nine planets from the sun. Pluto was discovered in February 18, 1930 by Clyde Tombaugh. Plutos the only orbit planet in the Solar System after it was classified as an orbit planet back in 2006. The planet has nine moons total Charon, Hydra, Nix, Kerberos, and Styx. Although Pluto is the largest Dwarf Planet it's smaller than most moon of the other planets. Alongside Pluto is the eighth planet from the sun otherwise known as Neptune. Due to its blue coloration Neptune was named after the Roman god of the Sea. While neptunes the third largest planet with respect to mass, according to diameter it's the fourth largest. Neptune has 14 moons and a very thin collection of rings that are made up of ice and dust
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System.
Years and years ago, there were only eight known planets that orbit our sun; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Eight planets until that fateful day when Clyde W. Tombaugh discovered our ninth planet. Although, a little credit should be given to Percival Lowell,
Mars: Mars is the fourth planet from the sun and is named after the Roman God of War because of the red color is has. Mars is considered a terrestrial planet with a thin atmosphere made up of carbon dioxide.
The Earth was formed about 4.54 billion years ago in one in many galaxies. After many years have passed the Earth has evolved and land was created. Many species have formed also the life of nature. The land provides humans nutrients and resources for people to survive, such as nourishing foods and materials for building shelter.
With The Planets, Op. 32, composed 1914-1916, Gustav Holst incorporates a wide array of cultural and scientific references to create musical characters for each of the planets in our solar system. The scientific connection is immediately clear simply by looking at how Holst chose to order the movements. While he does not specifically place the planets in order of distance from the sun, they still follow a pattern that clearly references their positions in space. Mars, Venus, and Mercury open the suite, being numbers 3, 2, and 1 from the sun (neglecting to count Earth, which does not appear). Following this are Jupiter, Saturn, Uranus, and Neptune, being numbers 4, 5, 6, and 7 in order. While an awareness of their scientific positions is
The earth is so far the known planet to sustain life. Starting as small dense group, humans have populated the earth to where they the most populated species on earth. When humans first populated the earth, they did not live long lives. Disease, animals, and natural disasters made life on earth a nightmare. As humans
This makes the Venusian day equal to 117 earth days. It is thought that this slow rotation may be the reason why Venus has no magnetic field.
Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.
The terrestrial planets are Mercury, Venus, Earth, and Mars. These four planets are the planets that are closest to the sun. Terrestrial means earthlike; therefore, these planets are all earthlike because they have a solid ground. The terrestrial planets are the middle school years. The knowledge learned here orbits the sun. If the knowledge learned at the sun is not retained, a student may have a
