The solar system was formed billion years ago the formation of the solar system was caused by the collapse of a giant molecular cloud. Therefore in 1610 Galileo Galilei was the first to discover the existence of the solar system he discovered many small details about the sun and the moon. Galileo also discovered several points of light around Jupiter which looked quite strange he first thought that “the points of lights” were stars surrounding Jupiter but their strange positions fascinated him and decided to get into deeper details. However the solar system consists of a central star called the sun which is surrounded by eight planets named Mercury, Venus, Earth, Mars Jupiter, Saturn, Uranus, and Neptune. The solar system also consists of …show more content…
Stars that are extremely hot are blue stars and yellow stars are average temperature. Stars are also classified by in which nebula they’re in for example nebulas in the interstellar medium are largely composed of hydrogen. A size of a star also determines how much gravity they have the larger they are the more gravity they have. Luminosity is also how stars are classified however the brightness of a star depends on how far that specific star is from Earth.

On the other hand we have many more things in the solar system like all the eight planets that rotate around the sun. Each planet has its own characteristics and different structures. Mercury has a dark gray, rocky surface which is covered with a thick layer of dust that is made up of igneous silicate rocks and dust. Mercury is the smallest of all the eight planets with no moons and it’s also the first planet of the solar system and the hottest planet during the day but during the night is very cold which means we cannot live there. Out of all the planets mercury makes the fastest revolution around the sun in 88 days, a day at mercury is way longer than a day in earth which means that 59 earth day equals one day in mercury. Mercury has the same characteristics as our moon it’s covered with craters made by asteroids

Venus is so bright that u can see it during the day that sometimes it looks like a bright star in the morning or evening sky the cause of this is because Venus is close to earth and the closer the object the brighter it is from Earth. However Venus surface is the opposite from earth it’s covered with mountains, craters, volcanoes and huge lava plains. Venus atmosphere is mostly made up mainly of carbon dioxide with thick clouds with really high temperatures that it could melt lead. Earth is our home planet known as the “blue marble” which is the third planet away from the sun. Earth is the fifth-largest planet in the solar system consists of one moon which was formed billions of years ago when the whole solar system was created. Earth has a variety of colors and small details it looks like a blue marble with white swirls with some brown, yellow green and white areas. The blue part of earth represents water which can be an ocean, lake, rivers, and streams all of this water takes 71 percent of earth’s surface The white swirls represent clouds and the atmosphere which is air made up of different gases mainly nitrogen and
