Planet and Star Size Comparison

Via THS Earth/Space Science (a weblog for a 9th-grade science class), I came across this neat animation comparing the relative sizes of planets in our solar system and various stars. It really does a good job!

Humans evolved on Earth, and our brains do a poor job grasping sizes much larger (or much smaller) than that which we’d find in our typical environment. True, we can describe it mathematically, but it’s so difficult to really see the comparison.

Unfortunately, I do not know who the creator of this video is. No credits are given, and a web search was unsucessful. It is perhaps European, based on the spelling of the star names. If anyone has any information, please let me know.

Update: It appears the original video used copyrighted music without permission of the copyright holder, and has been removed. I changed the post to a different version of the video without music.

Update #2: The old link no longer worked (thanks, Sara!) so I updated it.
