Compare the size of the earth with other planets

Now compare it with Uranus & Neptune This is the Earth

Now Earth against Sun This is the Earth Against Sun, Earth is like a dot  Think !! Where do you find yourself now?? This is the Earth

Suppose if we assume Sun as a 100 inch - for Demo   Actual Scale Diameter Body kilometers inches mm Sun 1391900 100 Mercury 4866 8.88 Venus 12106 22.092 Earth 12742 23.252 Mars 6760 12.336 Jupiter 139516 254.595 Saturn 116438 212.481 Uranus 46940 85.658 Neptune 45432 82.906 Pluto 3400 6.204 The Earth would be 23.253 mm

As we have compared the Earth with Sun Now As we have compared the Earth with Sun Now !! Start comparing the Sun with the Universe

The Nearest Stars from Sun The closest star to the Sun is only 7000 times further than the edge of our solar system. This map shows all of the stellar systems that lie within 12.5 light years from us.

The Solar Neighbourhood Universe within 250 light years This map is a plot of the 1500 most luminous stars within 250 light years. All of these stars are much more luminous than the Sun and most of them can be seen with the naked eye. About one third of the stars visible with the naked eye lie within 250 light years, even though this is only a tiny part of our galaxy.

Corner of the Milky Way galaxy 4000 light years away The Sun is located in the Orion Arm - a fairly minor arm compared with the Sagittarius Arm, which is located closer to the galactic centre. The map shows several stars visible with the naked eye which are located deep within the Orion arm. The most notable group of stars here are main stars in the constellation of Orion from which the spiral arm gets its name. All of these stars are bright giant and supergiant stars, thousands of times more luminous than the Sun. The most luminous star on the map is Rho Cassiopeia - to us 4000 light years away, it is a dim naked eye star, but in reality it is a huge supergiant star 100 000 times more luminous than our Sun.

The Universe within 50,000 Light Years The Milky Way Galaxy A spiral galaxy of at least two hundred billion stars. Our Sun is buried deep within the Orion Arm about 26 000 light years from the centre. Towards the centre of the Galaxy the stars are packed together much closer than they are where we live. Notice also the presence of small globular clusters of stars which lie well outside the plane of the Galaxy, and notice too the presence of a nearby dwarf galaxy - the Sagittarius dwarf – which is slowly being swallowed up by our own galaxy.

Now!! Canyou find the Solar system agaisnt the Milkay way. Although the Milky Way is but one of billions of galaxies in the universe, the Galaxy has special significance to humanity as it is the home of the solar system. As a guide to the relative physical scale of the Milky Way, if the galaxy were reduced to 130 km (80 mi) in diameter, the solar system would be a mere 2 mm (0.08 in) in width.

The Universe within 5,00,000 Light Years The Satellite Galaxies Number of large galaxies within 500 000 light years = 1 Number of dwarf galaxies within 500 000 light years = 9 Number of stars within 500 000 light years = 225 billion . The Universe within 5,00,000 Light Years The Satellite Galaxies The Milky Way is surrounded by several dwarf galaxies, ypically containing a few tens of millions of stars, which is insignificant compared with the number of stars in the Milky Way itself. This map shows the closest dwarf galaxies, they are all gravitationally bound to the Milky Way requiring billions of years to orbit it.

Can you find the Milky Way in this?? Our Milky Way galaxy is part of Local Group & it is in centre The Universe within 100 million Light Years The Virgo Supercluster Number of galaxy groups within 100 million light years = 200 Number of large galaxies within 100 million light years = 2500 Number of dwarf galaxies within 100 million light years = 25 000 Our galaxy is just one of thousands that lie within 100 million light years. The above map shows how galaxies tend to cluster into groups, the largest nearby cluster is the Virgo cluster a concentration of several hundred galaxies which dominates the galaxy groups around it. Collectively, all of these groups of galaxies are known as the Virgo Supercluster The second richest cluster in this volume of space is the Fornax Cluster, but it is not nearly as rich as the Virgo cluster. Only bright galaxies are depicted on the map, our galaxy is the dot in the very centre.

The Universe within 1 billion Light Years The Neighbouring Superclusters Galaxies and clusters of galaxies are not uniformly distributed in the Universe, instead they collect into vast clusters and sheets and walls of galaxies interspersed with large voids in which very few galaxies seem to exist. The map above shows many of these superclusters including the Virgo supercluster - the minor supercluster of which our galaxy is just a minor member. The entire map is approximately 7 percent of the diameter of the entire visible Universe.

The Universe within 2 billion Light Years

The Universe within 14 billion Light Years The Visible Universe This map attempts to show the entire visible Universe. The galaxies in the universe tend to collect into vast sheets and superclusters of galaxies surrounding large voids giving the universe a cellular appearance. Because light in the universe only travels at a fixed speed, we see objects at the edge of the universe when it was very young up to 14 billion years ago.

You are a believer!!! Good for you! Now, Do you really believe that the universe was Created 6000 years ago? Do you really believe that the creator of such a universe asked us to please him by offering sacrifices? Do you really believe that he ordered his messenger to kill all the men, women, Children and animals of some nations? Well, if you do… You are a believer!!! Good for you!
