If you are interested to learn more about the outer space, it will be the perfect time for you to read about the solar system facts below. Human being is so curious about the outside condition. Solar system is one of the important things to know beside the other objects used as research like the moon. Let’s see the 10 interesting solar system facts. Here they are.
1.dwarf planets of solar system
Let’s begin the first solar system facts by discussing about its dwarf planets. Some people probably have not recognized much about such planets. There are four dwarf planets that you should realize. Those are Pluto, Eris, Ceres and Makemake.
In this solar system, we only recognize that earth is the only place for living people. Since most people like to know more about the other planets, the spacecrafts have been built to accommodate the need. Some of them have been sent to moon, asteroids as well as dwarf planets. NASA is the biggest department which dedicates itself to research on the outer space object.
3.8 planets of solar system
The third position of the solar system facts is a bit surprising. At school, your teacher always tells you that the solar system has nine planets. That’s not right since our solar system only has eight planets. Pluto is not considered as planet in 2006.
4.solar system extension
Can you tell me the size of the solar system? That’s a very hard question to respond since theoretically, the scientists state that the solar system’s size is two light years.
5. Solar system’s mass
The solar system’s mass mostly is composed from the material of the sun. It occupies up to 99.86 percent. Since the sun is largely contained hydrogen, you may see that the material found in the solar system is also hydrogen. The other materials may include rocks and metals.
6. Solar system’s orbit
Solar system is composed from some planets and other matters in the space in which the sun is placed as the center of the orbit. However, there are some other materials which are not centering the sun. One of them is Halley comet.
7.solar system’s age
To find out the exact age of the solar system is a bit impossible, but you do not need to worry since many scientists can predict its age. The scientists state that the solar system’s age is around 4.6-billion year old by conducting the research related to the sample of meteorites.
Milky Way is a very big galaxy containing myriads of space objects. Our solar system is in it. You know that a sun is a star in the galaxy, but you should discern that there are more than 200 billion stars form the milky way in which the sun is only one of them.
Astronomical science develops time by time. In the past, the scientists thought that the earth was the center of the system in this galaxy. However, such false thought can be banished by Nicholas Copernicus who can accurately depict that the sun is the center of the system in the late of 17th century.
10. Stars near the sun
You need to identify that only few stars can be seen around the sun. Alpha Centaury is the nearest one since the distance is just 4.4 light years. Then it is followed by the Barnard Star, Wolf 359 and also Lalande 21185.
