Greetings, Question for any Astronomy buffs. Wondering if this might be a good anology to clue someone in to the size of the earth in comparison to the Milky Way galaxy. Might be understating or overstating, but trying to get a real world comparison.... Take a sports stadium, like the Rose Bowl or something like that. Wouldn't the Earth be about the size of a BB or a marble, compared to the Rose Bowl ( the galaxy ).... is my thinking right? TIA! :cheers2: SnF
ah, never mind....google is your friend...:svengo: I think my analogy is off a little.... maybe a speck of dust in the Rose Bowl!!! ...
28,000 light years to the center.. the sun is 8 light minutes from earth so if I got my math right .. the center of the milky way is about 2 billion times further than we are from the sun.. and new news puts us at about 100,000 miles a sec around the center http://www.space.com/scienceastronomy/090105-aas-milky-way-mass.html
Watch this video and then watch it again. https://www.youtube.com/watch?v=I34FNr_peUk We aren't even a speck really in the grand scheme of the universe.
It's a speck. From Mars Earth is a TINY point of light blue light. http://www.msss.com/mars_images/moc/2003/05/22/ From further out it's not even visible with the eye. The edge of the solar system is known as the heliopause, it's where the Sun's influence no longer exists and intersteller space begins.
Back to my analogy....probably wouldn't even be an atom in the Rose Bowl....Wow..humbling for sure...
Hi, there is a short movie called 'The powers of ten' (maybe available on youtube or other sites) that relates the sizes of the smallest and the biggest structures in our universe. But no person can image how large a lightyear or even a lightminute really is. That are just numbers. Regards Gyro
