Prepare to be amazed by the HUMONGOUS size of our universe and the planets and stars within.
It Really IS a Small World We’re Living in!
If you've always had trouble understanding the true sizes involved in astronomy, you will be astonished and amazed by the size of the earth, compared to other planets and stars within our universe.
The scales involved are so mind-boggling, how could we ever think we are alone?
The following pictures and video are the best visual images that I've ever seen that shows how minuscule earth is.
Note: the precise (km in diameter and distence measurements) shown below are estimates, and not 100% correct, due to the different distences I researched at many reputable astronomy related websites. Including Wikipedia
Here Are Some of Our Planets
Pluto, the smallest was discovered in 1930, by the American astrologer Clyde W. Tombaugh and named after the Roman god of the underworld. It was classified as a dwarf planet in 2006. It is 2,376.6 km in diameter.
Mercury was first observed by the astronomer's Galileo Galilei and Thomas Harriot in 1610 and is named after the Roman deity Mercury, the messenger of the gods. It has the most craters in the solar system and is the smallest planet in our solar system. It is 4,879 km in diameter.
Mars, often described as the red planet was first identified by Galileo Galilei in 1610 and named after the Roman god of war and the second-smallest planet in the solar system measuring in at 6,779 km in diameter.
Venus, named after Aphrodite, the ancient Roman goddess of love and beauty, is the brightest planet in the sky. It is referred to as the 'morning star' and 'evening star' and was first seen with a telescope by Galileo Galilei in 1610. Mars is about 12,104 km in diameter.
Earth is the only planet not named after a mythological being. It was once believed to be the centre of the universe. Earth is around 12,756 km in diameter and the third planet from the sun.
Keep scrolling as Earth gets a lot smaller!
Look how small Earth looks next to Neptune!!
Neptune was named after Poseidon, "the Roman god of the sea" and is the smallest known gas giant in the solar system and the farthest known planet from the sun. It is 49,244 km in diameter. There is much controversy as to who first discovered this planet.
Saturn was first observed by Galileo Galilei with a telescope in 1610. It was named after the Roman god of agriculture and is the sixth planet from the Sun. Saturn is the father of Jupiter and is 116,460 km in diameter.
Uranus, often referred to as an 'ice planet' looks tiny compared to the gas giants Jupiter and Saturn. Uranus was named after the Greek god of the sky and was first observed by the British astronomer William Herschel in 1881, and named by the German astronomer Johann Elert Bode. Uranus is 50,724 km in diameter.
Jupiter is the largest planet in the solar system and the 5th planet from the sun. It was discovered by Galileo in 1609 and was named after the Roman god Jupiter. It is 142,984 km in diameter.
As we venture towards the gas giants of our solar system, Jupiter, Saturn, Uranus and Neptune are barely visible. Earth is just about visible at this scale and Jupiter, the giant among planets in our system is just a single pixel and is 318 times bigger than Earth.
The Sun, the yellow dwarf star is 100 times bigger than Earth and is 1.39 million km in diameter and is the star at the centre of the universe. More than one million Earths could fit inside the sun.
As we travel farther into space, even the Sun looks tiny compared to Sirius, Pollux and Arcturus.
Sirius. This 'white to blue colour' star was first observed by the American astronomer and telescope maker, Alvan Graham Clark in 1862. Sirius is called the 'Dog Star,' because it is part of the constellation Canis Major, Latin for "the greater dog." It is the brightest star in the night sky and is about 2.4 million km in diameter.
Pollux, also referred to as the 'crown'. This giant orange star is about 34 light-years from the Sun and is about 12.244 million km in diameter.
Arcturus, also referred to as 'Bear Watcher' or 'Guardian of the Bear' is the giant orange star at the centre of our solar system and was first seen by the French astronomer in 1635. It has a diameter of 35,748,800 km and is about 36.7 light-years away from Earth. Over 17,500 Suns will fit into Arcturus.
As we travel even farther out, even the massive stars look so small in comparison with these humongous sizes.
Rigel, the blue supergiant and known as 'the left leg of the giant' was first discovered by the German astronomer Johann Bayer in the early 1600s. It is about 116 million km in diameter.
Aldebaran, the fourteenth-brightest star in the night sky is a similar size to Orion and the brightest star in the celestial equator was discovered y the English astronomer William Herschel in 1782. Aldebara. It is 61.402 million km in diameter is 153 times brighter than the sun.
Betelgeuse, the orange-red star in the night sky is one of three stars that make up the Winter Triangle (an astronomical asterism formed from three of the brightest stars in the winter sky). It is about 1.234 billion km in diameter. The diameter of Betelgeuse is 141,863 times larger than the diameter of the Earth.
Pistol Star (not shown in images) is a blue hypergiant star and one of the most luminous known stars in the Milky Way. It was discovered using the Hubble Space Telescope in by the American astronomer Don Figer. It emits light 10 million times brighter than the Sun and is the brightest known star in the galaxy. (see the video further down the page)
Antares, meaning 'opponent to Mars' was discovered by Austrian astronomer Johann Tobia Burg in 1819. It is 10 times bigger than the Sun and 700 times the sun's diameter, and about 604 light-years from Earth
As we travel to the largest known stars, to try to comprehend the sizes involved here is mind-boggling and incomprehensible!
Mu Cephei was discovered by English astronomer William Hershal in 1848. This red supergiant star is 100,000 times brighter than the Sun with a diameter of 1.753 billion km, and is about 2,838 light years away from Earth
VV Cephei was discovered in 1936 by the American astronomer Dean McLaughlin. Its diameter is 1,900 times that of the Sun and is 1,400.00 times bigger than the Sun, and is about 5,000 light years away from Earth.
VY Canis Majoris was first observed by the French astronomer Jarome Lalande in 1801. This supergiant star has a diameter of around 1.9758 billion km and is about 3,900 light-years from the solar system.
Unbelievable 'mind-boggling' sized star in our universe is UY Scuti
UY Scuti (not shown in video below) is a hypergiant star which was discovered by German astronomers at the Bonn Observatory in 1860. It is the largest known star (that we're aware of) and is 5 billion times that of the Sun and is 2.3765 billion km in diameter. 6 quadrillion 489 trillion Earths can fit into the volume of UY Scuti.
Earth: Amazing Feats
- May 20, 1932, the American aviation pioneer Amelia Mary Earhart, became the first female aviator to fly solo across the world. It took her just under 15 hours.
- July 22nd, 1933, the American aviator Wiley Post became the first male pilot to fly solo around the world in an Aircraft named Winnie Mae. It took him 7 days, 18 hours and 49 minutes.
- June 20, 1970, the American adventurer Dave Kunst was the first person to walk around the Earth. It took four years, three months and 16 days.
On the grand scale of things with potentially, hundreds of billions of galaxies within the universe filled with over 1,000,000,000,000,000,000,000,000 planets, and an estimated 1 billion trillion stars in the observable universe, It makes everything in life - all my problems and worries feel so insignificant and unimportant. To the point of feeling as insignificant to life as a grain of sand!

comparing to those other planets we are small because those other planets are bigger than us and whitch we live in a small world
Karolina on March 26, 2012:
Fantastic hub, looking forward to come back and see your new posts. Thank you. www.karoline-art.com
jeyaramd from Mississauga, Ontario on January 01, 2012:
This hub gives a whole new meaning to the saying "its a small world". I think we should be more environmentally conscious in safeguarding our little earth. Global warming and environmental issues are very real. Thank you for sharing these wonderful pictures. Great hub.
Bob on January 17, 2011:
Yep, other planets and other stars are much bigger...
but the space in between is billions of times larger.
nick on October 20, 2010:
i... feel.... so....
krishna on April 27, 2010:
Thanks for this wonderful piece of information. Although I wouldn't feel insignificant we are. Just understand the human developed technology is able to give such comparisons,facts.Lets believe in years to come we unravel much more mysteries.Hats off to our scientists!!!

how exactly does looking at a red ball help with depression
PhotoShowMan4U from United States on March 19, 2010:
Nice photos! May be I should do a Photo Show on the Planets.

Thank you for the permission.
... and glad to hear u feel better now compu-smart. Something had to be done after u lost ur sleep because of my comments a little while back (about 2 weeks ago) lol!
Sweet Dreams ... Have fun.
A Student of Life.
Abbas on December 19, 2008:
I don't think this stuff is too too bad anymore ... well so long as we don't discover giant humans on other planets (like Antares) that have also discovered in their lives that their planet is as puny as our earth is in these pictures lol ...
that would be just sad ... and that i think is an understatement!! lol
and hey u can sleep peacefully so long as we can be sure that we are not just some chemical elements for giants on other planets (like we "earthlings" use atoms/molecules for science experiments lol) ... hmm, what particle would we be? alpha is taken lol!!
also, can i copy these images compu-smart?
alisha on December 10, 2008:
Great picture!!!!!!!!!! hoping for many more too
Dr Kulsum Mehmood from Nagpur, India on December 07, 2008:
Makes me feel so small and insignificant. For all egoists this hub is a great ego-buster. Good photographs compu-smart
Abbas on December 06, 2008:
lovely ... so do I exist? ... goes to show that nothing could happen merely by "chance" ... all creation has to be guided. The complexity of even a human that is infinitely tiny on the shown scale has even tinier stuff that helps in survival of species. God's creation is awesome! ... Still scary ... I still am unsure if I exist!! (not literally) ... and if there is some creature on some big planet, they would be monsters ... it's a good thing they have not been discovered yet!! we would be like dust in their toenails!! :(
Ashley Eklund on December 02, 2008:
Does anyone know the original source of these images?
abhishek(nepal) on December 02, 2008:
wow!! it's really unbelievable and amazing images i am really happy to seeing it. it's very nice
Asghar Ali Soomro on November 27, 2008:
Its really amazing and remind us about the creater of this universe. Who is one and only that is Almighty ALLAH.

Sreeman on June 07, 2008:
it really satisfied my hungry on unbelievable pictures
nashomega on May 11, 2008:
this is Fantastic... We are just another dot in space! That is true!
