The Solar System and the Sun: Looking for the Solar system GK. Do you want to study the basic information about the Sun? Here are the post about the Solar System and the Sun.
Our Solar System
The solar system comprises the sun 8 planets, their Satellites, and other non-stellar objects, which are believed to have been developed from the condensation of gases and other bodies.
The sun is at the center of the solar system and all the planets revolve around it in an elliptical orbit.
Sun is the Nearest star to the Earth
The size of the Solar system has been estimated to at about 105
Components of the Solar System
Our Solar system consists of
- The Sun
- Eight planets and their satellites
- Drifting particles (InterPlanetary dust and electrically charged gases called Plasma)
Origin of the Solar SystemVarious theories were given to explain the Origin of the solar system
|Planetesimal Hypothesis||Chamberline and Moulton|
|Tidal Hypothesis||Sir James Jeans and Harold Jeffreys|
|Binary star Hypothesis||HN Russel|
|Supernova Hypothesis||F Hoyte|
|Inter-stellar Dust Hypothesis||Otto Schmidt|
|Electromagnetic Hypothesis||H Alfven|
|Protoplanet Hypothesis||G Kuiper|
|Nebular Cloud Hypothesis||Dr. Von Weizsacker|
The sun is the center of the solar system. It is made up of extremely hot gases (Hydrogen) and other lesser bodies.
Important facts or GK about Sun
- The sun is 109 times bigger than the earth.
- The Sun’s weighs is 2×10 27 tonnes more than earth.
- Distance between the Sun and earth is about 150 million km.
- The light from the Sun reaches earth in about 8 minutes 18 Second.
- The Glowing surface of the Sun is called ‘Photosphere“.
- The red color portion above the “Photosphere is called “Chromosphere“.
- The last portion of the Sun is called “Corona“, which is visible during eclipses.
- The temperature in the core of the Sun is about 15 million degrees, Kelvin.
- The temperature of Photosphere is about 6000-degrees Celcius.
- Newly discovered planet in our solar system is 2003 UB 313.

Some of the Concept associated with the Sun
The sun is continuously emitting streams of proton in all direction either as spiral streams called solar Wind or bouts of incandescents material called Solar Flares.
Solar flares being hot ionized gases pose danger to satellite Communication.
The constituents particle of the solar wind is trapped by the Earth’s magnetic field and enter the Earth’s upper atmosphere as Aurora.
It is described as Aurora Borealis in the Northern hemisphere and Aurora Australis in the southern hemisphere.
Plages and Sunspots
The surface of the Sun is continuously changing. Bright spots are called Plages and dark spots are called Sunspots. The Sunspots dark regions years. These spots greatly influence the global climate.
