OUR SUN


The Sun is the star at the center of the Solar System.  Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.

1.Age
   The Sun is 4.6 billion years old.Now it has crossed it's middle-aged. The Sun has already burned off about half of its store of Hydrogen. It has enough left to continue to burn Hydrogen for approximately another 5 billion years.
2.Size
   The diameter of Our sun is approximately 1,392,684 km.Around one million Earths could fit inside the Sun.
3.Mass
   The Sun contains 99.86% of the mass in the Solar System.The mass of the Sun is approximately 330,000 times greater than that of Earth.
4.Temperature
   The temperature on the surface of the Sun is closer to 5,600 degrees Celsius.The temperature inside the Sun can reach 15 million degrees Celsius.
5.Shape
   The Sun is an almost perfect sphere.There is only a 10 kilometre difference in its polar diameter compared to its equatorial diameter which is much less than earth's diameter difference.
6.Energy Source of Sun
   The energy created by the Sun’s core is nuclear fusion. This huge amount of energy is produced when four hydrogen nuclei are combined into one helium nucleus.
7.Atmosphere of Sun
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 "
8.Solar Wind
   Every second, the Sun sends to earth 10 times more neutrinos than the number of people on earth.
9. Power of Sunlight
   Every second, the Sun sends to earth 10 times more neutrinos than the number of people on earth.
10.Future of Sun
In about 5 billion years, the Sun will deplete its supply of hydrogen and helium, turning into a red giant star, consuming Mercury and Venus and maybe even Earth.

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...
