The sun has many mysteries and a lot of interesting facts. So without wasting time here are the most exciting and fun facts of the sun. To start off lets talk about the sun’s age which is about 4.6 – 5 billion years old and for that age the sun is middle-aged. So the sun is a star and there are many different types of stars but the sun is a yellow dwarf star. Many people wonder where the sun’s location is and the answer is that the sun is in the middle of our solar system and is 147 – 152 million km. Now here are the basics of the sun but what about the diameter of the sun? So the diameter of the sun is 1,392,684 km and this is actually small compared to other stars. We learned about the diameter but now lets talk about its volume. The volume of the sun is a lot but it is very low compared to other stars. The sun can fit approximately 1 million earths inside it. So we know many things about the sun but we don’t know how fast it travels. The answer is simple, the sun travels about 220 km per second. We forgot one thing which the temperature of the sun and the surface temperature is 5500o C while inside the sun can be more than 15 millionO C. Well here are some interesting facts about the sun.

We just learned the basics now lets go deep inside the sun. The sun is amazing but did you know that it consumes four million tons of hydrogen every second. Also, it contains 99.83% of mass in the solar system. Talking about hydrogen, the sun used half of its hydrogen in the past 4.6 billion years. We talked all about the sun but did you know that the sun’s gravitational pull hold all the planets in place so the planets don’t fall down. I know that we already talked about the diameter but the sun’s diameter is 110 times wider than earth’s. The sun is like a planet because it has layers too which are core, middle and outer layer, photosphere, flares, chromosphere and the corona. The sun is very important to us because without it we wouldn’t be living. The sun also produces solar winds which causes radio interference at times. Did you know that the sun’s gravity is 28 times for than Earth’s. There you have it interesting facts about the sun!

I think that our solar system is one of many because of many reasons. I think our solar system is one of many because astronomers think that there are more than two billion galaxies in the universe so I think that in those two billion galaxies there should be at least one solar system like ours. There are also many stars like the sun and they should be also having planets. Also, NASA says “Given how many they have found in our own neighborhood of the Milky Way galaxy, scientists estimate that there may be tens of billions of solar systems in our galaxy,perhaps even as many as 100 billion. Whether this estimate is correct and how similar other solar systems are to ours, remain to be seen” on their website. I came upon this website when I was surfing the web finding information on planets for my solar system catalogue. I go with NASA because they state that there are billions of solar systems in our galaxies. I think that there are many solar system in the two billion galazies with more than hundred billion Solar System.  So I think our so solar system is one of billions of solar system in the whole universe.
