We are told that in the Milky Way
there are millions and millions of stars and ever so many sun families.
Western astronomy placed on record with regard to its numbers also but,
who is there to verify all these? However we will just understand the
universe first in which we live. There is a Sun, everybody knows it,
and around this Sun the planets like Mercury, Venus, Earth, Mars,
Jupiter, Saturn, Uranus and Neptune which are travelling in the space in
a certain prefixed circle. However, we should realize that we are
living in this earth which is a part of the sun family and the fifth
largest planet in the solar system. This earth is the only planet known
to support life. It weighs roughly about 5, 97, 20,000 million tons
and its circumference covers 40,075 km. It is located 14, 95, 97,000 km
away from the sun. The earth circles itself at a speed of 1,670 km/h
and it took 23 hours 56 minutes 04.09053 seconds to complete one full
circle. By this time it travels 40,075 km on its path which we call as a
Day, besides it floats around the sun at a speed of 1,07,870 km/h by
this ratio in a single day it covers 25,41,450 km and in 365.2564 days
completes 940 million km we term this a year. In addition to that you
would be astonished to know that in the above process sun’s peripheral
atmosphere wind flows 400 km/second which accounts for 14,40,000 km/h.
What the beauty in it is that not only the planetary system travels in
the space but also we, the human beings, all the living creations
including vegetation and animals and the things which are placed on the
earth are all travelling such a long distance constantly throughout
the lifespan along with the earth without any obstacles, at the same
time we, as we are standing, walking, swimming, playing etc. on the
earth could not feel the happenings in the universe. Is it not an
amazing to you to imagine all the happenings?
Similarly,the moon, which is a natural
satellite to the earth, we see the moon in the sky is encircling the
earth in 28 days. It weighs 735,000 million tones and its circumference
covers 10,919 km. It is located 4, 07,000 km away from the earth.
This sun family is said to have number of moons viz. Earth 01 moon,
Mars 02 moons, Jupiter 63 moons, Saturn 34 moons, Uranus 27 moons and
Neptune 13 moons, but the Mercury and Venus have no moons. Besides dwarf
planets like Pluto and Eris, countless comets, asteroids and meteoroids
are there. This info’s are subject to changes according to the vision
of the scientists then and there. But, it is true that the said above
are encircling the sun. Likewise we can say plentiful about the sun
family and the universe endlessly, but we cannot just imagine the
entirety of the cosmos with the facts just emerging from the sun family
known to our eyes and knowledge. So, I leave the rest of the depth about
the cosmos to your imagination!
