OUR JOURNEY WITH MOTHER EARTH

.            The Milky Way galaxy 

Many of us travel a good distance every day. Some about 100 km and some other much above it. The actual journey we make is not in hundreds or thousands but in millions of kilometres. For example, when we go to sleep at 10.00 pm we are at a place. When we wake up at 6.00 am next day we are at a different place. That is, during the sleep of 8 hrs we traveled a distance of 24,293,360 kilometres. It is not an imaginary figure but a scientifically approved fact. We may go through the following scientific data.

Earth rotates on its axis at a speed of 1670 km/hr. The circumference of earth being 40,075 we all travel this distance or something less depending upon our location on the earth.

The earth orbit round the sun at a speed of 107,000 km/hr. In 365 days our mother earth travels a distance of 940 million km 

Then comes the solar system consisting of the sun, planets, moons, dwarf planets, asteroids, comets and other small bodies which together orbit the centre of the galaxy at a speed of 828,000 km/he. It takes 230 million years to complete one orbit.

Then our Milky way galaxy orbit around its centre at a speed of 2.1 billion km)hr . The Milky Way is a barred spiral galaxy with 100,090 light years across which contains 200 billion stars.

Considering the above scientific data the distance we travel is as below.

1 hr -       3,036,670 km
8 hrs -   24,293,360 km
24 hrs - 72,880,080 km
