Our Solar System


Our Solar system of one star and eight planets was born about 4.6 billion years ago. All of the pieces were created at the same time.  It took billions of years for the entire system to develop. All of the gases, dust, and pieces of the system were around at the start. Eventually a star, eight planets, some smaller dwarf planets (like Pluto), and an asteroid belt developed. There wasn't even a star when the Solar System started out. 

 1. Age
     The Solar System was formed approximately 4.6 billion years ago, it is derived from the study of meteorites.
2. Father of Solar System
   99.86% of the system’s mass is found in the Sun and the majority of the remaining 0.14% is contained within the solar system’s eight planets.
                             Sun is the head of our solar system
3. Size
  The diameter of solar system is 18.75 trillion kilometers.
                Time taken by present space shuttle to reach out from our solar system will be approximately 73087 years.  
4. A Huge Family
    Our solar system is just a huge Family.  It has 1 star (The Sun),8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune),5 dwarf planets (Pluto, Ceres, Haumea, Makemake, and Eris),181 moons, 566,000 asteroids and 3,100 comets.
5.Terrestrial Planets
    The four smaller inner planets, also known as the “terrestrial planets” (Mercury, Venus, Earth and Mars), are primarily composed of rock and metal.
6.Gas Planets 
  The four outer planets, also known as the “gas giants” (Jupiter, Saturn, Uranus and Neptune), are substantially larger and more massive than the inner planets.
7.Ice Planets
   The two outermost gas giants, Uranus and Neptune, are composed largely of ices, (water, ammonia and methane) and are sometimes also referred to as the “ice giants“
8. Heliosphere
  The heliosphere is the immense magnetic bubble containing our solar system, solar wind, and the entire solar magnetic field. It extends well beyond the orbit of Pluto.
                              " We live inside the atmosphere of Sun "
9.Kuiper Belt
    The Kuiper belt  is a circumstellar disc extending from the orbit of Neptune (at 30 AU)(1 AU=149,597,870.7 kilometres, distance between sun and earth) to approximately 50 AU from the Sun.It is far larger—20 times as wide and 20 to 200 times as massive as compared to asteriod belt. it's asteroids are composed largely of frozen volatiles (termed "ices"), such as methane, ammonia and water. The Kuiper belt is home to three officially recognized dwarf planets: Pluto, Haumea, and Makemake. 
10. 243 Lda
    243 Ida is an asteroid in the Koronis family of the asteroid belt. Amazing fact about this asteroid is that it has it's own moon.

Mercury    Mercury is the closest planet to the Sun.Mercury is one of four terrestrial planets in the Solar System, and is a rocky body like Earth. It is the smallest planet in the Solar System 1. Size    It has the diameter of 4,879 km which make it "smallest" planet of solar system. 2. Mass    It has mass of   3.30 x 10^23 kg (5.5% of Earth).Therefore, it has only 38% of gravity as compared to earth.                      3. Second Hottest Planet    Instead of closest planet to sun, it is not the hottest planet, because it has no atmosphere(because of weak gravity) to regulate the temperature, therefore it has large variation in temperature during night(-170 degree Celsius) and day(430 degree Celsius). 4. Day and Year    A year in Mercury is 88 days, yet a Mercury day is 176 Earth days. 5.Second Densest Planet     After the Earth, Mercury...

Saturn Saturn is the sixth planet from the Sun. It is best known for its fabulous ring system .It is the second largest planet in our solar system .  Like Jupiter, it is also a gas giant and is composed of similar gasses including hydrogen, helium and methane. Some amazing facts About Saturn: 1.Visible to naked Eye    It is the fifth brightest object(after Sun,Moon,Venus and Jupiter) in the solar system and is also easily studied through binoculars or a small telescope.                                    2.Year and Day    Saturn spins on its axis very fast. A day on Saturn is 10 hours and 14 minutes, whereas Saturn goes around the Sun very slowly. A year on Saturn is more than 29 Earth years.                                 3.Rings   Saturn is best known for ...

Jupiter Jupiter is the largest in the   Solar System  and fifth planet from the Sun. It is a gas giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Some amazing facts About Jupiter: 1.Visible to naked Eye    Jupiter is the fourth brightest object in the solar system. Only the Sun, Moon and Venus are brighter. It is one of five planets visible to the naked eye from Earth.                                            2.S hortest Day   Jupiter turns on its axis once every 9 hours and 55 minutes. It has the shortest day of all the planets.                             3. Year    Due to the large distance of Jupiter from sun, it orbits the Sun once every 11.9 Earth year...
