 Introduction to Solar System

           SOL- Roman God of sun. Within the universe we have numerous galaxy one such galaxy is one such galaxy is milky way galaxy. Which is discovered in 1704 the term solar system was first appeared in English in 1781. Star is defined as a huge ,a massive body of luminescent matter radiating enormous amount of energy second. Each star holds around itself ,under the influence of force of gravity, a variable number of relatively small sized ,non-radiating bodies of matter, called Planets. The basic difference between star and a planet is in their masses: a star is thousand times bigger than a planet . Because of such an enormous mass very high temperatures are reached in the interior of a star that make it radiate energy.

Components of Solar System

           The nine planets and the sun are the main bodies of solar system. The planets revolve around the sun along regular stable and nearly circular paths called orbits,that lies almost in the same plane. The planets on the basis if their distance from the sun and other broad similarities, the nine planets conveniently fall into two groups

Inner planets

        Four planets , namely Mercury, Venus, the Earth , and Mars constitute the terrestrial group. They are characterized with:
  • Relatively smaller masses
  • Higher densities 
  • Shower speeds of rotation and
  • Less number of satellites.

Outer planets

        They are also called superior planets and include five members Jupiter, Saturn, Uranus,
Neptune,and Pluto . They are Characterized with (with the exception of pluto)
  • Very larger masses
  • Much lower densities
  • Faster rotations and
  • Higher number satellites
      Note: ( We gonna discuss the deep geological backgrounds of these planets in our upcoming blogs)

Moons

         Moons are the natural satellites of the planets.  Natural Satellites Or Moons are defined as the celestial body that moves around planet.Moon of the earth is the 5th largest in the solar system,and its 1/4 of the earth diameter. The distance between the moon and earth is around 3,84,400 km. The tides in the oceans were formed due the Gravitational attraction between the moon and the earth. Ganymed- the largest moon in Solar system and it is in Jupiter. Titan would be the second largest moon in solar system and is of the Saturn.

Asteroids 

         Small Rocky substance exist between mars and Jupiter .

Meteoroids

         Small Particles moves around the sun.

Comets

         Comets are cosmic snowballs of frozen gases ,rock and dust ,they have tail like structure  and they orbit around the sun.

Pulsars:

        Pulsars are highly magnetized bodies rotating compact star that emits beams of electromagnetic radiation our of its magnetic poles.

 Intresting facts in Geology Facts behind eye of Sahara:            World's largest has a eye like structure which is actually formed by differential erosion by wind. Eye of sahara also called as the Richat structure is prominent circular feature in the Sahara's Adrar plateau, Northwest Africa. The Richat structure is a highly symmetrical and deeply eroded dome, of 40 kilometer in diameter exposing sedimentary rock on layers which appear as concetric rings.The sedimentary rock exposed in this dome ranges in ages from late proterozoic within the center of of the dome of Ordovician sandstone around its edges.           Facts in ghats of South India:             Almost 80% of the rainfall in India is contributed by the monsoons, these monsoons are maintained by mountain ranges in coastal planes. Such as Western Ghats and Eastern Ghats. Western Ghats are formed during the breakup of gondwana s...

Origin of the Solar system

  Origin of the Universe:           Before discussing how the solar system formed we have to know about the origin of the universe. The origin of universe is the origin of everything, multiple scientific theories and creation myths from around the world have try to explain it’s mysterious genesis. However the most widely accepted explanation is the Big Bang theory. Big Bang theory:    The Big bang theory states at that the universe began as a hot and infinitely dense point. Only a few millimeters wide it was similar to the super charged black hole.    About 13.7 billion years ago this tiny singularity violently exploded. And it is from the explosion this bang that all Matter, energy and time were created.   What happened next were two major stages of the universe’s evolution, called the radiation era and Matter era. They are defined by the key events that helped shape the universe              Ra...

Exploring Solar system - 2

  Outer planets:            Outer planets were called as gas giants (Jovian) planets, they are made primarily of gas, mostly hydrogen do not have solid surface. A space ship cannot land on it (but it can crash through its atmosphere). And the outer planets Jupiter, Saturn, Uranus, Neptune. In this blog post we will discuss the geological facts of these gas giants. Jupiter:         Jupiter was the solar system’s first planet. Jupiter was the fifth planet in the solar system and the largest planet in the solar system. This giant does not have a solid core rather this one has a liquid core surround by a worldwide ocean of hydrogen and helium gases. Jupiter’s gaseous composition can be observed in its atmosphere about 44 miles thick the atmosphere is a canvas of strips and storms churning across the giant planet. Their colors range between shades of whites, yellows and reds all caused by the different chemical makeup of each area. Jupit...
