Our Solar System
For thousands of years people have been observing the stars and planets, interpreting events from their movements and exploring the universe from Earth. Ancient civilizations such as in Egypt, China, Greece, and India made attempts to find certain regularities of those planets. They were related to navigation as well as the early notions of the universe. Most of the explanations considered the Earth as the center of the universe, until Nicolas Copernicus rejected this system called Geocentric, proposing the heliocentric system with the sun in the center of the planets rotating around it. It took several years for this theory to be proven. Thanks to people like Galileo today we know the term of our solar system.
What does the solar system consist of?
The solar system is the planetary system where we find the earth and other astronomical bodies which revolve in an orbit around a large star called the Sun. The sun is the only part of the solar system that emits light by itself. Thanks to this, the sun is a source of electromagnetic energy in the solar system. The Planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are also part of the solar system, as well as their surrounding asteroids and comets.
The sun contains 99.8% of all matter in the solar system. The planets, which are condensed from the same material from which the sun is formed, contain only 0.13% of this. Nevertheless, Jupiter contains more than twice the matter of all the other planets together. The satellites of each planet, comets, asteroids, and the interplanetary medium form the missing percentage.
But there’s something else
The interplanetary space is a space in the solar system which is a vacuum. It includes some forms of energy and is composed mostly of two materials which are interplanetary dust and interplanetary gas.
