THE PLANETS AROUND US
PLANETS AROUND OUR EARTH
Astronomy is one of the wonderful subjects which can absorb us. It has lots of mysteries which do not have any end. It has solar system, nebulas, galaxies, and many more which are yet to be discovered. All these are present in the UNIVERSE. It is enormous.
The eight planets: The center of our solar system is the sun. Eight planets are rotating around it. Pluto, which was earlier considered as planet, has now been devoided of that position They are-
1) Mercury-It is the nearest planet to the sun. It is the smallest planet in the solar system. It takes 88 days to revolute around the sun. It is a little red in colour. It is a lifeless and dry world covered with creators. Deep below the surface there is a large core of iron. The planet’s gravity is too weak to hold on to the atmosphere and so heat is lost at night. Difference between day and night temperatures can be 600 degreeC (1,080 F).
2) Venus-Sunlight on the cloud tops makes Venus shine brightly in the earth’s sky. As it moves it appears to go through phases similar to those of the moon. The dense clouds trap the suns heat to make it hottest of the planets. The acid clouds and unbearable pressure make it doubly inhospitable. Beneath the clouds are volcanic plates of deserts covering about two thirds of the planet.
3) Earth-Largest of the four inner planets. Earth is the only solar system planet to support life and to have water in abundance. Earth has changed enormously since it was created 4.6 billion years ago. It has developed an atmosphere and gone through climatic and structural change. Internal heat currents push the land masses by up to 7 cm (3in) each year.
4)Mars- It is the most earth-like planet.It’s little more than half of ther earth’s size.Has polar ice caps. It looks red due to iron iron ridge rocks and dust covering much part of it. About 40%of its surface is rock desert. It has canyons which is 4500 k.ms long and 7k.ms deep.It is its main characteristic feature.
5)Jupiter- it is the biggest and most natural planet with 61 moons. Has rocky core which is 10-20 times massive.It also has metallic and liquid hydrogen.14%Helium is also there.The rings we see around it. Were discovered in 1979.
Indian astronomers called it ‘GURU’ or ‘BRIHASPATHI’. According to Indian astrology, this is most powerful planet.
6)SATURN – Indian astrology calls it a bad planet. It is the slow moving planet.According to that, it takes 2 ½ years to pass one house(30 degrees) in the zodiac cyscle.it isd the second largest planet in the solar system It has 33 moons. Here Hydrogen surrounds surrounding a rocky core. This too has rings around it. The rings look colourful.Rings have 17 colours.
7)Uranus- Discovered in 1781.Very far from sun.Hydrogen is predominant in its atmosphere,but Methane is present in the upper part.It has 26 moons.It has 11 rings.
8)Neptune- It’s cold planet. It similar in size to Uranus .Blue-green in colour because of Methane. It was discovered in 1846.Has 6 rings and 13 moons
All these planets are considered to be influencing on human life-according to Astrology. Science will not believe it. But, experience is the best guide. Indian astrology has well developed calaculation and explanation system.
I am thankful to little son Akshara prasd, who showed eagerness in producing a hub on this topic. He is about to complete his 12th year, shortly.He gives a very easy sentence to remember the order of therse planets;
MY VERY EARNEST MOTHER JUST SERVED US NUTS
Here, every letter in the beginning of each word indicates the planet in the order
