What is planet? A planet is a celestial body that is in the orbit of the sun. 1here are 9 planets in our solar system. 1. Mercury 2. Venus 3. Earth 4. Mars 5. Jupiter 6. Saturn 7. Uranus 8. Neptune 9. Pluto
Mercury planet Mercury is the 1st smallest planet in our solar system. We can also call this planet evening star. It the planet that close to the sun about 58 km and in diameter is 4,850. The temperature in the day rise to 800 0F (430 0C) and at night it will cold as -280 0F (175 0C). In this planet there is no atmosphere, rain, cloud, wind or water, and no living thing in this planet. Mercury 1
Venus is the planet that close to our earth and we also can call this planet as the earth’s twin. This planet is the hottest planet in our solar system and the distance of Venus to the sun it take 108 million kilometers (67 million miles). The surface of the Venus is cover by the soil and it also have the mountains and volcanos. It also have toxic atmosphere at there. Venus 2
The Earth The earth is the third planet that close to the sun and the distance is in 150 million (93 million miles). For 71% of earth surface is cover by water and 29% is land. The earth takes 365 days to round the sun. The earth has one moon and the distance is 384,629 km. Earth is the only planet that living thing can live on it. The atmosphere on earth is exist of 78% nitrogen, 21% and 1% other gases. 3
Mars is a rocky planet that contains iron oxide and we can also call “the red planet”. The distance of the Mars to the sun is 228 million km and it take 687 days to round the sun. The surface there mountains, volcanoes, and craters. Because there have a high quantity of carbon dioxide, no water, and have a little amount of oxygen so, it is not impossible for the living thing to exist. Mars 4
Jupiter is the largest plants in our solar system and it orbits has about 484 million miles (778 million km). To complete one orbit of the sun it takes about 12 earth years. The atmosphere at there is made up of hydrogen and helium. There are also more than 75 moons at Jupiter. Jupiter 5
Saturn is the second biggest planet in our solar system and it also have many rings around it. The distance of Saturn to Sun it takes about 886 million miles (1.4 billion km) and it also take 29 Earth years to round the orbit of the sun. there are 82 moons on the Saturn. Saturn is a gas planet and the atmosphere at there is made up of hydrogen and helium. Saturn 6
Uranus has 2 sets of rings and 27 known moons. Surface of the Uranus is as an ice giant and the atmosphere at there mostly is hydrogen and helium. To complete the one orbit of the sun the Uranus will take 84 Earth years and the distance to the Sun is 1.8 billion miles (2.9 billion km). Uranus 7
Neptune is cold giant plant and it has a dark spot on it. Neptune has a radius of 15,299.4 miles (24,662 km) and it about 4 time wider than our Earth. It distance to the sun is 2.8 billion miles (4.5 billion km) and it take 165 Earth years to round the sun. At Neptune it has 14 known moons and 5 main rings at there. The atmosphere at there is made up of hydrogen, helium, and methane. Neptune 8
Pluto is the last planet in our solar system. The wide of Pluto is about 1,400 miles and there are 5 moons at the Pluto. To complete one orbit of the Sun it take 248 Earth years and form Pluto to the Sun it will take 3.6 billion miles (5.8 billion km). the atmosphere at there is made of carbon monoxide, methane and nitrogen.
