The Sun By Mrs. Steele’s Class Jones Valley Elementary Huntsville, Al. What is the sun? The sun and all stars are large balls of hot gasses. The gasses are mostly hydrogen and helium. The temperature on the sun’s surface is about 11,000 degrees F. The sun has been around for about 4.5 billion years and will burn for another 5 billion years. The Sun The sun is an average or medium size star. There are stars that smaller and larger than our sun. The sun is just the right size and distance from Earth so that there can be life on our planet. There are stars that are much larger than our sun. A star in the Orion constellation called Betelgeuse is 400 times larger than our sun. If our sun was this size it would engulf Mercury, Venus, Earth and Mars. The Earth in 93 million miles away from the Sun. Light travels so fast that it only takes eight minutes for sun light to hit the Earth. Don’t be tricked! The sun does not move. The Earth is moving around the sun. It takes 365 and ¼ day for the Earth to make one full rotation around the sun. It looks like the sun is going east to west across the sky because the earth is turning. It takes the Earth 24 hours to make one turn. This causes day and night. What the sun does for the Earth! The sun keeps the Earth from being a frozen planet. The sun warms land quicker than water these different temperatures causes wind and weather. The sun feeds the plants. Without sunlight all plants would die. The Sun gives Earth life! The End
