A planet is a celestial body in our solar world, and from which there are different species. The two types of planets are Jovian and terrestrial. Terrestrial planets are Earth-like and more Earth-like than Jovian. The Jovian planets include Earth and its moons, Venus, Mars and Mercury. These planets have variations among themselves, in terms of atmosphere, pressure, temperature, surface features and the possibility of water.
The first is about the planet on which we compare others and the Earth on which we live. Earth is very distinct among all the planets. It is believed to be 4.6 X 10^9 years old. The figure is not round, but has an ellipsoidal or geoidal shape. Earth is the third planet from the Sun in our solar system and the largest of the terrestrial planets. Obviously we have the best information on Earth because we are here. Earth has an atmosphere, a layer of gas that surrounds the planet and is restrained by gravity. This sphere contains Nitrogen, Oxygen, Argon, Water and Carbon Dioxide. The pressure of air is 10,330 g/cm^2 with an average temperature of 10C. The surface of the Earth is very dynamic and in two circles, consisting of dry land and ocean. It consists of silicate and basalt. Because of the tectonic plates (16 plates) at the center of the Earth, we have earthquakes and volcanic eruptions. Earth contains the most water of any planet in the solar world, from liquid ocean basins to frozen ice caps and water vapor. a> in the atmosphere.
We have the most information on the Earth’s moon, compared to the moons of other planets. It is roughly 384,400 km from Earth. It has many impact basins, from small to 3,000 km wide. Bowls with basins are the most common on the surface. The temperature can range from 103K to 383K. There are some molar fields that are eaten out of the lava, and also some mountains (walls of the basin and blankets ejected.) On the other hand, there is no motion of the Earth’s plate, while the Moon is one plate and has no motion. There is no water on the moon, which indicates very little chance for life on the moon.
Mars is a very interesting planet. The planet was the focus point of alien life and other such science fiction stories. It is the fourth planet from the Sun and can be referred to as the Red Planet because of its appearance from Earth. The surface of Mars is thought to be made of basalt. It is also common to believe that there was once liquid water on the surface of the planet. There is no magnetic field on Mars, but some parts of the planet indicate that the crust was magnetic. Mars also has some interesting surface features. Many impact craters and plains from lava flows. It also contains the highest mountain in the Solar System, Mount Olympus, which is three times the height of Mount Everest. the land. Compared to the Earth, Mars has a thin atmosphere, which is dusty, and gives a very different appearance than the Earth. Air contains Carbon, Nitrogen and Argon, Oxygen and Traces of Water. There is a great possibility of liquid water, not just solid ice. Some photographic evidence shows water. Earth and Mars are very closely compared when it comes to the times because of the similar inclinations of the two planets, although the times on Mars are twice as long as the times on Earth. In winters, temperatures can go down to -220F in winters and up to 70F in summers. Mars also has evidence that shows it has the largest dust storms of all the planets. It is said that Mars is close to the Sun, which can increase the global temperature and create these storms.
Venus is the second planet from the sun and the sixth largest planet in the solar system. It has an iron heart and a mantle crust. Compared to Earth, Venus’ rotation is slower. The Earth is a little smaller in comparison to the diameter and mass it shows, which is why many say that Venus is the sister of the Earth. Not only are they similar in size, but the surface of both planets has few craters, and the makeup and chemical density of the planets are very similar. This connection to Earth could be related to life, but the opposite is true. Venus is said to be very unlikely to support life in our solar world. The atmosphere is very different from that of the Earth. It has immense pressure and density and is composed of carbon dioxide. The clouds on Venus contain most of the sulfuric acid ac. Because of the density of the air, the greenhouse effect is multiplied by that of the earth. The temperature can reach 400 to 740 K. Compared to Mercury, which is twice as close to the Sun, it is twice as hot, showing the greenhouse effect of Friday. Most of the surface is level with some relief. It has two notable depressions and mountainous regions. Venus could hold an enormous amount of water at one time, but it was boiled away by the heat, leaving the planet extremely dry. It also does not have a magnetic field, but the interior of Venus is very similar to Earth’s. A very interesting effect since it happened in 2012 and involved Friday. It is called the transit of Venus, and it has not been since 1882. Venus passes between the Sun and the Earth, and appears as a huge black hole in the Sun.
The last of the terrestrial planets is Mercury, which is the smallest of the four. It is the closest planet to the Sun and the largest of the eight in the Solar System. Like Venus, the planet’s main layers are an iron core and mantle. It is close to the surface of our moon, which has many craters. These craters range from small to very large diameters. It has a low magnetic field and compared to Earth’s extreme temperatures (temperatures can range from -292F to 802F.) the density is also close to Earth’s. Mercury, like Mars, has a thin atmosphere and contains hydrogen, oxygen, sodium and helium. The atmosphere is not stable because mercury is very small due to its gravity, and it is difficult to retain any atmosphere. Mercury has a slow rotation and an even stronger magnetic field compared to some of the other terrestrial planets. Mercury has ice caps, but the planet contains the least amount of water.
Why is space and exploration so difficult? Why can’t we live on other planets? There are many reasons why, most of them very obvious. There are small amounts of oxygen and water, if any, on other planets. With this, the pressures and temperatures of other terrestrial planets would make human life impossible. Living in a shared space has many effects. Technology and human bodies are the two main obstacles. Today’s technology can’t have the life span to account for machines and technology. Most of our bodies are not suitable for living in space, let alone other planets, even though they are Earth-like. The human body has a huge a> gravity, air and water requirement. Without exercise in space, we would lose muscle tissue, which could result in organ failure. Medical News Today (www.medicalnewstoday.com) states that another aspect of gravity in the tissues is that space travel can alter the body’s natural clock and affect astronauts. This shows that there are not only physical limits and barriers, but psychological issues associated with space travel and on other planets. He has conquered the obstacles before men, and the distance is near. Many say that space is the last frontier and the possibility of human life on other planets with the right knowledge, which today’s technology will not provide.
