people say that "we live in such a small world". they don't know that it's literally. I saw a picture and heard in a documentary that jupiter, the largest planet in our solar system is 1 milion times larger than the Earth. the sun is about 4 times larger than jupiter.i than saw a picture about a planet or star (i don't know what it is) Arcturus larger than the sun. i uploaded the picture. can you believe how small we are?? because i can't...it's actually so amazing.
ps: i could only upload one picture. you should google the rest: planet comparison...by the way the bigest ever known is VY Canis Majoris.
if a human could walk on the surface of Canis Majoris – assuming a speed of 5 km/h (3 mph) for 8 hours a day – the person would have to walk for 650,000 years to circle the star (compared with 2 years 11 months to complete the same task on the Earth, and 310 years 7 months on the Sun).

Hi mtgrlz_zerocool,
It is rather spectacular to see the diminutive proportions of our planet Earth when compared against Uranus or Neptune or Saturn or Jupiter, or most especially the Sun.
In rough figures, both Uranus and Neptune are about 4 times wider than Earth, and so about 64 times Earth's volume.
And both Saturn and Jupiter are roughly 10 times wider than Earth, or around 1,000 time greater volume.
But the Sun dwarfs all of them, even Saturn and Jupiter!
The Sun is over 100 times wider than the Earth, which translates to a volume more than 1,000,000 times greater than Earth, and about 1,000 times greater than either Saturn or Jupiter.
It's really beyond me to try to grasp such stupendous dimensions, at least not compared to the normal measures that we might experience in our daily lives. Earth is big, but there's big, and then there's BIG.
