Solar system The sun and the celestial bodies circling around it is called the Sun's family or the solar system. There are nine main planet in the celestial bodies circling around the Sun. According to distance Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune and Pluto and the satellite of this planets are also called the member of the Universe. Despite of these Meteors, caudal stars, Astrodes etc. are also the member of the solar system. They all are rotate continuously in the oval shape around the celestial body sun.
Mercury:- It is the smallest planet of the universe and closest to the sun. It takes 88 days to complete the orbit of the sun and it take same time to complete rotation on its own axis. It is very difficult to see them because it is very close to the sun. But whatever studies have been done in this regard it shows that there are many hills on its surface. There is no water in this planet. It is about 30,600,000 miles away from the sun.
Venus:- It is the closest planet to the Earth. It is about 67,100,000 miles away from the sun. It is about equal to the earth in expansion and weight. It takes 224 days to complete the revolution of the Sun. It takes 30 days to complete rotation on its axis. Atmosphere is present on it. The Human have been sent his rocket. It is sent by Russia.
Earth:- The earth is a unique planet in the universe on which living organisms survive there. It is about 92.96 millions miles away from the Sun. It takes 365 and 1/4 (one fourth) to complete the revolution of the Sun. It takes 24 hours to rotate on its on axis that cause day and night. Moon is the satellite of the earth which rotates around the earth. It causes moon-night and dark-night.
Mars:-There is a red look of the Mars. This is the only one planet which the sign of vegetation are found After The Earth. Study of Mars shows that there are ice mounds on it. This planet is about 141,000,000 miles away from the Sun. It takes about 687 days to complete the orbit of the Sun. It complete the cycle in 24 hours 37 minutes on its own axis. This planet has two small satellites which name is Phogos and Diamos.
Jupiter:- Jupiter is the largest planet of the Solar family. This planet is about 483,000,000 miles away from the sun. It takes11.9 years to complete the orbit of the sun. It complete cycle in 9 hours 50 minutes on its own axis this is 17 times heavier than our Earth. Being away from the sun, it is extremely cool. It has 12 satellites.
Saturn:- This is also unique Planet of the universe. It is about 886,000,000 miles away from the Sun it take about 29 and 1/2 half years to complete the orbit of the Sun. It complete cycle in 9 hours on its own axis. This planet has many rings Saturn has 9 satellites but so far only one exactly study about Cotecone.
Uranus:- It takes 84 years to complete the orbit of the Sun. It complete the cycle in 12 hours on its own axis. It has 4 satellites. It is about 178,300,000 miles away from the Sun.
Neptune:- Neptune takes about 165 years to complete the orbit of the Sun. It takes about 16 hours to complete the cycle on its own axis. it is about 2,794,000,000 miles away from the sun. It has only one satellite.
Pluto:- Pluto is the farthest planet of the sun. It takes about 247.7 years to complete the orbit of the sun. It takes 153 hours to rotate on its own axis. It is about 367,000,000 miles away from the Sun.
In addition to this planets about 1500 small satellites are orbiting the sun. These are called Astrodes. It is actually small pieces broken by big planets rotating around the sun.
