Unbelievable Pictures and Video to Help You Comprehend How Small the Earth Is
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.
Here Are Some of Our Planets
Pluto 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. Earth is almost a Sphere, yet the Flat Earth Society believe the Earth is flat!

Look how small Earth looks now!
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 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 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 video below)
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, the 3rd largest star 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.
VV Cephei, The 2nd largest star is 5,000 light-years from Earth 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.
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 3,900 light-years away from Earth.
The largest mind-boggling known star in the 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.
With hundreds of billion 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. For me, It makes everything in life, all my problems and worries feel so insignificant and unimportant, especially on the grand scale of things!
Do you think that "intelligent life" exists on a Planet in a Universe somewhere?
