The solar system is about the system of the sun and the eight largest planetsare rotating around the sun. The solar system is formed by the billion years ago.The Four outer planetcan be rotate around the sun. The four inner planets are the smaller that is the mercury, Venus, earth, and mars and the largest planet is the Jupiter or Saturn.
Theseplanets can rotate around the earth. These are the planet that can revolve around the sun. The only on planet is available where we can live and it is called the earth. The atmosphere of the earth is best and can suit our nature. We can survive only in the earth in other planet we cannotsurvive because the atmosphere of the other planet is not the perfect for the living. Some planet is the hot planet and some planet is the cold that where we cannot survive. The atmosphere of the earth is normal. In the solar system the sun and star is present. The eight planets can be rotate around the sun and the earth is the 3th planet from the sun
List of the planets:
Mercury is the nearest planet to the sun and it is the smaller planet. This is the larger plant than the earth and it is the rock planet of the solid surface. The atmosphere of this plant composed that the human cannot take the breath. It has no moon and the ringscannot be around this planet.
Venus is the 2nd planet from the earth and the rotating period of this planet is bout the 243 earth days. It is the opposite direction to the planet. This is 2nd nearest planet to the sun and the surface of this planet is volcanic. This planet is the moon less and rings less. The temperature of this planet is about the 800 degree. Theatmosphere of this planet is about the super rotating that can complete the in every 5 days.
Earth is our home planet and it can be the 3rd planet from the sun. This is the only planet were we can survive. The size of the earth is small and its distance from the sun is about the 90 million miles. Theearth can rotate in the 24 hours and it is called the 1 day. We can survive on this planet because it is a rocky planet and have a dynamic surface. Thisplanet is the ring less planet. The moon of this planet is 1. The atmosphere of this planet is the great and has many oceans can be present in this planet. The protection layer can be protecting the earth from other atmosphere. This is the best place to live.
mars is the 4th planet nadit is coldest planet from the sun. Thisplanet is the smallest planet. the number of this palnt in the solar system is 4th and the distance is about the 280 million from the sun. the day of this planet is longer and it can complete the one orbit is about 685 days around the sun. this planet is the rocky planet and the surface of this palnet is solid. the atmosphere of this planet is the thin including the carbon dioxide and has the samll amount of the oxygen. there are the no rings around this planet and the has the double moon planet. thispalnet can not to support live on this planet.
jupiter is the 5th planet from the sun. the size of the jupiter is bigger from the earth and look like a basket ball size. the distance from the sun of this palnet is about the 490 million. it can complete the one rotation is about the 11 earth year. in the atmosphere of this palnet the helium and hydrigen amount is present. there are the 75 + moon present in this palnett and has this planet is the solar ring system.
thesaturnpalnet is 6th planet from the sun and the distance of this palnet is about the 885 million from the sun. the day of this planet is shorter about the 10 hours and the year is longer about the 29 earth yaers. it is the gas gaint planet and the surface of this planet is the solid. the atmosphere of this planet is the hot air including the helium and hydrogen. wecan notsurvie in this planet and it is the mini solar system .

A look up at the sky at night uncovers an expansive broad strip of light. This captivating line of light is the focal point of our universe, as observed from one of its external arms. Understanding the structure of the Milky Way has always been a difficult challenge as the Universe is huge enough to study. The close planetary system sits on the external edges of one arm in a circle of material. Cosmic systems are rambling frameworks of residue, gas, dim issue, and anyplace from a million to a trillion stars that are held together by gravity. Almost all enormous systems are thought to likewise contain dark gaps of huge masses at their focuses. In our system, that is the Milky Way, the sun is only one of around a hundred to four hundred billion stars.
Many observations and debates had been done on the Milky Way. Everybody was eager to know the reality behind this mystery. The band of light was first resolved into separate stars by a renowned space scientist “Galileo”, with his telescope. Galileo's discoveries are very famous.Cosmologists imagined that every one of the stars, known to mankind, is contained in the Milky Way. This assumption was done at the start of the 1920s. There was a big debate between Harlow Shapley and Heber Curtis about the topic. Later on, observations were made by Edwin Hubble and he brought up a conclusion that the Milky Way is actually one of the galaxies.
Milky Way Galaxy
Galaxy contains a star and many planets revolving around it. This galaxy is known as Milky Way Galaxy. The more profound we investigate the universe, the more cosmic systems we see. One examination was done in 2016 that evaluated that the perceptible universe contains two trillion or 2,000,000 million galaxies. A portion of those far off frameworks resembles our own Milky Way world, while others are very distinct. Milky Way is probably the only galaxy where life exists. What bounds the gas, dust and the big group of stars in the galaxy, is the gravity. The Milky way system is an enormous banned winding spiral galaxy. There are stars of various shapes and sizes. We see stars at night and wonder they are near but in reality, they are very far and appear in our Milky Way. The name Milky Way was given to our galaxy since it shows up as a smooth band of light in the sky when you see it in an extremely dark area. Since there are many stars in the galaxy, so it is difficult to count their number from the position where we are. An estimate says that there are around a hundred billion stars.
A light-year is mostly used to express astronomical distances. Since our solar system is much far away from the galaxy, so we can somehow say that solar system lies about twenty-five thousand light-years away from our galaxy.Our world likely contains hundred to four hundred billion stars and is around one hundred thousand light-years over. That sounds enormous, and yet it is. The Andromeda galaxy, known to be our neighboring galaxy, is around two hundred and twenty thousand light-years wide. We live in the outskirts of the galaxy.Just like the Sun circumvents the focal point of the Milky Way, the Earth circumvents the Sun. So, it takes almost two hundred and fifty million years for our sun and the planetary group to go right around the focal point of the Milky Way.
What NASA says about Milky Way
The National Aeronautics and Space Administration (NASA) is the US government agency that is in charge of aviation research, air transportation, and the ordinary citizen space program. Where explorers chart the continents of the globe, out astronomers have engaged themselves in making up the map of the spiral structure of the Milky Way. Utilizing infrared pictures from NASA's Spitzer Space Telescope, researchers have found that the Milky Way's exquisite winding structure is overwhelmed by only two arms. Beforehand, our cosmic system was thought to have four noteworthy arms.
NASA’s James Webb Space Telescope is the most dominant as well as complex space telescope. It will investigate the universe utilizing infrared light, from planets and moons inside our close planetary system to the most antiquated and far off galaxies.When we talk about the tremendousness of the universe, it's easy to hurl out enormous numbers, however progressively hard to fold our brains over exactly how huge and far various divine bodies truly are.
At the focal point of the spiral, a great deal of vitality is generated along with clear flares, once in a while. In light of the massive gravity that would be required to clarify the development of stars and the energy discharged, the space experts infer that the focal point of the Milky Way is a dark hole having a mass of millions or billions of times than that of the sun.Different galaxies have different shapes. Some galaxies have circular shapes, and a couple of others have strange shapes just like toothpicks or rings.
