The Size of Our Universe

You don’t need to be a scientist to figure our that our universe is huge! A universe is commonly defined as the totality of everything that exists, including all space, time, matter, energy, planets, stars, galaxies, intergalactic space, and beyond. Definitions and usage vary and similar terms include the cosmos, the world and nature. Scientific observation of earlier stages in the development of the universe, which can be seen at great distances, suggests that the universe has been governed by the same physical laws and constants throughout most of its extent and history. Below I included a lot of different facts about what we know about the universe and our planets. It’s very interesting and it’s only a matter of time before NASA and scientists come out and prove the existence of other ‘Earth-Like’ planets and even the knowledge of Extraterrestrial-Life. Enjoy reading the information and pictures below which was collected by Sinter Klaas on Abovetopsecret:

The average distance is about 30 earth’s diameters, or 384.300 km / 238.792 mi.

1 pixel is 600 km / 372.822 mi. But because of the elliptical orbit, it varies between 363.000 km and 405.500 km.

Now you can compare the Earth and the Moon. The Earth is big as a basketball and the Moon is more like a marble. Now you can get a good idea on how far they really are!

The total surface area of the Moon is about the size of Africa. Although it’s one of the biggest Moons in the Solar System, it’s still pretty small. Now the next picture is the planets compared to Jupiter:

A couple pictures that show you the differences between the planets including the Sun:

In our Solar System we use the term ‘AU’ which stands for the Astronomical Unit. 1 AU is the distance between Earth and the Sun. There is about 100 AU between the Sun and Saturn which is 100 times the distance from the Earth to the Sun. THe Proxima Centauri is our closest neighboring star and it’s about 271,000 AU from the sun, which is about 4.22 light years away.

So in theory; light only needs about 8 minutes to get here. But it needs about 4.22 years to get to Proxima Centauri. These are the closest neighboring stars from the Sun. The diameter starting from the Sun reaches out only 15 light years.

It gets even more amazing! You might have learned that our Sun is classified as a small yellow dwarf in school. But the size comparison will really blow your mind when the Sun is places next to other stars and remember all of these stars are found in our own galaxy. The Sun with the other planets:

The Sun next to Sirius:

Arcturus next to Antares:

Antarus isn’t even the largest star known to man. There are way bigger stars out there…

A Bigger Picture of the Universe.. Just amazing!

Remember these are only just stars and they are part of a even more massive place called the Nebula Lagoo which is part of the inner galaxy of our universe..

There are over seven of these planetary Nubula’s. These Nebula’s are the remnants of the stars as they blew out of their final layers of gas which only leaves a white dwarf in the center that fades away eventually.

Next is a even bigger Nebula called the ‘Steller Nursery’ It’s the Cat’s Paw Nebula from our own Milky Way:

And now the Carina Nebula, where starts have already been going ‘Hyper Nova’. It’s also near own region of the Galaxy.

The most famous star out there is the Eta Carina which is around 100 times the mass of the Sun and it’s ready to explode! The giant dust clouds are from an earlier release of its solar matter…

Now here is a bigger picture of our Milky Way:

Now imagine that our Milky Way is part of a big cluster of galaxies which is also part of a super cluster of more galaxies.. Even if you imagine that to be the one of many clusters; you are still far from knowing the true size of the universe and it’s contents.. Science still has a lot of explaining to do! The Hubble Telescope focused only a small patch of sky, which was no bigger than the size of a stamp and it shocked many of the scientists! What they found was that there are billions of stars and planets in our universe alone.. (Within that size of a stamp) So just think if the range was bigger! We are living in a world that is huge and there is no way that no intelligence-life forms are out there! They are just not telling us the truth… Now in the picture below, every dot is just another galaxy.. Imagine that! If you have any other information to add please send me an email at
