Introduction -
● Our galaxy is Milky Galaxy ( or the Akash Ganga ) . It is spiral in shape. Nearest galaxy to ours is Andromeda.
● Our solar system consists of a star( Sun ) , 8 planets and countless fragments of left-overs called asteroids,meteors,comets and satelites of the planets.
The Sun :
● It is one of the stars in the Milky Way galaxy.
● The sun is 109 times bigger than on earth and weighs 2×10^27 tons.
● The energy of sun comes from the fusion of hydrogen into helium.
● Sunlight takes 8 minutes 16.6 seconds to reach earth.
● The sun's present age is 5 billion years and the total life is 10 billion years.
Mercury :
● Revolution : 88 days ( Fastest revolution in Solar System ).
● Maximum diurnal range of temperature.Its days are scorching hot and nights are frigid.
● It has no atmosphere and no satellite
Venus :
● Also called Earth's twin,because it is slightly smaller than earth ( 500 km less in diameter ).
● Popularly known as Evening star and Morning star. It is seen in the east in the morning and in the west in the evening.It is not possible to see it all over the night.
● Brightest planet ( because of 0.65% albedo , the reflecting power ).
● Closest planet to earth.
● It is hottest planet in the solar system. It is because of the Green house effect as its atmosphere contains 90-95% carbon dioxide.The night and day temperatures are almost the same.
● Rotates backward ( clockwise ) unlike others.
● No satellite.
Mars :
● Also called 'Red Planet'.
● Recent explorations have thrown light on the possibilities of existence of life here.
● It has 2 satellites- Phobos and Deimos.
Jupiter :
● Largest of all planets ( 71% of the total mass of all planets ). Called 'Lord of the Heavens'.
● It gives off more energy than it receives from the sun,beacause of the heat inside.
● Its atmosphere contains hydrogen,helium,methane and ammonia.
● A great red spot is detected on it.It represents a huge storm.
● It has the fastest rotation time ( 9.8 hours ) in the solar system.
● It has 63 satellites ( Prominent are Europa,Gannymede & Callisto ).Gannymede is the largest satellite of solar system.
Saturn :
● Second in size after Jupiter
● Revolution : 29 years. Rotation : 10.3 Hours.
● Least density of all ( 30 times less dense than earth ).
● Unique feature is its system of rings ( 3 well defined ).
● 31 satellites ( Prominent is Titan ).
Uranus :
● Rotates from north to south as it is inclined at an angle of 98° to its orbit.
● Surrounded by a system of 9 faint rings.
● Has 21 satellites ( Prominent are Miranda,Ariel,etc ).
Neptune :
● Revolution : 165 years.
● Rotation : 15.7 days.
Moon :
● Circumference : 11,000 Km , Diameter : 3475 km, Gravitational pull : 1/6 th of Earth.
● Takes 27 days 7 hrs 43 mins and 11.47 second to complete one revolution around earth.
● Rotates on its axis in exactly the same time as that of its revolution.That is why we see only one side of the moon ( only 59% of the surface ).
● Moon has no atmosphere.
● Moon-light takes 1.3 seconds to reach earth.
● Neil Armstrong and Edwin Aldrin reached moon on July 21, 1969 on Apollo XI ( landing spot is called 'Sea of tranquility' ).
