SOLAR SYSTEM.....?
THE SOLAR SYSTEM WAS FORMED ABOUT 4560 MILLION TEARS AGO. IT IS MADE UP OF THE EIGHT PLANETS-MERCURY , VENUS , EARTH ,MARS , SATURN , JUPITER, URANUS,NEPTUNE AND AS
WELL AS THEIR MOONS , COMETS, AN OTHER BODIES . THESE ALL ORBIT AROUND THE SUN.
LETS STUDY ABOUT ITS MEMBERS..........
THE SUN
SUN IS THE NEAREST STAR FROM US. ITS
MASS IS EQUIVALENT TO 99.98% OF THE
MASS OF THE ENTIRE SOLAR SYSTEM
ELEMENTS. IT IS MOSTLY MADE UP OF
TWO LIGHT GASES 75% HYDROGEN, AND
23%HELIUM WITH RELATIVELY SMALL
QUANTITIES OF OTHER ELEMENTS SUCH
AS GOLD. IT HAS A SURFACE
TEMPERATURE OF 5880K(KELVIN). IT
SPIN AT A DIFFERENT RATE.
THE PLANETS
A CELESTIAL BODY MOVING IN AN
ELLIPTICAL ORBIT ROUND A STAR IS
CALLED A PALNET . PLANETS DO NOT
TWINKLE AND KEEP CHANGING THEIR
POSITIONS WITH RESPECT TO STARS .
MERCURY MERCURY IS AN SMALL ROCKY PLANET WHOSE SURFACE HAS BEEN HEAVILY CRATERED BY METEORITES . THE SURFACE ALSO HAS MANY RIDGES CALLED RUPES, YHAT ARE BELIEVED TO HAVE FORMED AS THE CORE OF THE YOUNG PLANET COOLED AND SHRANK. MERCURY MOVES FASTER THAN ANY OTHER PLANET. SURFACE TEMPERATURE ON THE PLANET IS 430C ON T5HE SUNLIT SIDE AND -170 ON THE DARKER SIDE.
VENUSVENUS IS SLIGHTLY
SMALLER THAN THE
EARTH AND PROBABLY
WITH A SIMILAR
INTERNAL STRUCTURE
OF A PARTLY MOLTEN
METAL CORE
SURROUNDED BY A
ROCKY MANTLE AND
CRUST. BEING THE
HOTTEST PLANET OF
OUR SOLAR SYSTEM IT
HAS A SURFACE
TEMPERATURE OF 480C.
IT ROTATES FROM EAST
TO WEST AND HAS NO
MOON OF ITS OWN.
EARTH
THE FIFTH LARGEST PLANET
IN THE SOLAR SYSTEM. THE
EARTH IS THE ONLY PLANET
TO SUPPORT LIFE. THE AXIS
OF THE ROTATION OF THE
EARTH IS NOT
PERPENDICULAR TO THE
PLANE OF ITS ORBIT. THE
EARTH ONLY ONE MOON. ITS
ATMOSPHERE IS PROTECTED
WITH A LAYER OF OZONE.
MARS
MARS IS ALSO KNOWN AS THE
RED PLANET BECAUSE OF THE
RED IRON OXIDE DUST THAT
COVERS ITS SURFACE. IT IS
ORBITED BY TWO TINY MOONS
PHOBOS, DEIMOS.
JUPITER
JUPITER IS THE LARGEST MOST MASSIVE PLANET OF THE SOLAR SYSTEM.IT HAS TWO FAINT RINGS, AND IT IS ORBITED BY ITS 16 KNOWN MOONS. ITS AVERAGE TEMPERATURE IS +14.85 TO +19.85.
SATURN
SATURN IS THE SECOND
LARGEST PLANET IN THE
SOLAR SYSTEM BUT THE
LEAST DENSE. ITS
DINSTINCTIVE RINGS ARE
MADE OF ICE AND ROCK
WHICH WERE PROBABLY
PARTS OF COMETS AND
ASTERIODS. IT APPEARS
YELLOWISH IN COLOUR.
URANUS
URANUS IS THE THIRD LARGEST PLANET IN THE SOLAR SYSTEM. IT IS A COLD GAS GIANT BELIEVED TO CONSIST OF A MIXTURE OF GAS AND ICE AROUND A SOLID CORE. URANUS IS TILTED AT 97.9 AND SO ROLLS ON ITS SIDE ALONG ITS ORBITAL PATH. IT HAS 15 MOONS 10 FAINT RINGS AND A BROAD RING OF DUST.,
NEPTUNE
THE NEPTUNE IS BELIEVED TO CONSIST OF A SMALL SOLID CORE SURRUONDED BY A MIXTURE OF LIQUIDS AND GASES . IT HAS FOUR UNSTABLE RINGS AND 8 KNOWN MOONS.

IT EXISTS ON NORTH POLE OF THE EARTH
IT IS SITUATED IN THE DIRECTION OF THE EARTH AXIS
IT DOES NOT APPEAR TO MOVE
