Universal Perspective & the relative size of planets

This video shows the relative size of the Earth to the other planets, the sun and to other suns much bigger than our own. For years I've known, or read, that the Sun is a million times bigger than the Earth. For the first time I see the relationship. Then comes Arcturus which dwarfs our sun. Antares is bigger still. I wonder, though, is there really only one Earth? A Native American told me that there are 500,000 planets like Earth in our universe and that there are 27 different universes. "Fascinating" as Spock was fond of saying. Even if there were millions of Earth-like planets, this planet called Gaia is the only one I know of like Her in existence. Special thanks to Dawn Tiger Love for sending me these photos.

I have a question: where is the audio track from? It just has this unnerving, unsettling feeling to it; I sort of like it.

[DavidLakota]

That sound is one of Mac iMovies built-in sounds. I think it is called "Foreboding".

Pluto isn't a planet!

There are not "500 trillion" galaxies. The estimates are all around 100 billion. Not to say it isn't still a huge number, but that it is an even bigger numerical difference. Also you CANNOT see "240 billion" stars with the naked eye. Even with a small telescope you can't see much more than one hundred thousand, and with the naked eye you can't see much more than three thousand. I hate to do this, but your ending facts are just incorrect - check any encyclopedia.

@Mammasaymammasaw Just in the last year they've discovered many earthlike planets in our own galaxy.

@ultimatejoshman1 Pluto's not a planet for a long time now. Its a dwarf planet, like hundreds of others orbiting our sun on the edge of the solar system.
