(Pluto is no longer classified as a planet, but it’s there for size comparison. As for the Sun, it was never a planet but is here for the very same reason.)
I always wanted to see a one-by-one comparison of the sizes of the planets, so I put the numbers into my 3d program. These are all correct proportions (of size, not distance).
Tamen, the final planet, was a world we created when we were children. Obsessed with size, we said it was 1,000 times larger than Earth’s sun (this was actually only 100 times larger, because 1000 made the sun so small you couldn’t really see it). We later learned that such a planet would have to much gravity that not only would no living thing survive, but you may get a nice little black hole started right there in the planet!
Wow… and I just realized that had the sun have been sitting where it is in this video, it’d be sucked into the planet instantly.

Hubble Space Telescope Reveals Pluto’s Changing Surface.
4th February 2010- http://uk.news.yahoo.com/18/20100204/tsc-blushing-pluto-dwarf-planet-takes-on-e123fef.html
Pluto, the dwarf planet on the outer edge of our solar system, has a dramatically ruddier hue than it did just a few years ago, NASA scientists said Thursday, after examining photos taken by the Hubble Space Telescope.
They said the distant orb appears mottled and molasses-colored in recent pictures, with a markedly redder tone that most likely is the result of surface ice melting on Pluto’s sunlit pole and then refreezing on the other pole.
The remarkable color shift, which apparently took place between 2000 and 2002, confirms that Pluto is a dynamic world undergoing dramatic atmospheric changes and not simply a ball of ice and rock, according to scientists at the US space agency.
They said they will compare Hubble pictures taken in 1994 with some from 2002 and 2003, as they search for more signs of seasonal change, including evidence that Pluto’s northern polar region has gotten brighter, while the southern hemisphere has darkened.
“The Hubble observations are the key to… showing how it all makes sense by providing a context based on weather and seasonal changes, which opens other new lines of investigation,” said the leader of the study, principal investigator Marc Buie of the Southwest Research Institute in the western US city of Boulder, Colorado.
Pluto — declassified as a full-fledged planet in August 2006 — has a 248-year orbit and an axial tilt which, unlike Earth, alone drives the seasons. The icy orb’s seasons are asymmetrical because of its elliptical orbit.
Spring transitions to polar summer quickly in the northern hemisphere, because Pluto is moving faster along its orbit when it is closer to the sun, NASA said.
Scientists are hoping to collect additional riveting snapshots of Pluto when NASA’s next space probe, dubbed New Horizons, flies by the dwarf planet in 2015.
Hubble underwent repair during a space shuttle mission last year that left it with a new camera and spectrograph, as well as spruced up scientific instruments.
The repair job marked the end of NASA’s human missions to the beloved Hubble. Launched in 1990, the telescope was repaired and upgraded in 1993, 1997, 1999, 2002 and 2008.
Last year’s final upgrade extended the life of Hubble another five years.

The video starts looking at Pluto’s moon, Charon, and it visits all the planets of our solar system, including Earth. Then we move 100 light years away to circle the Sun, away again to 15.000 light years, travelling outside the galaxy, to finally travel 500.000 light years away from it.

There are stars in the background but the compression erased them so they are not really visible.

Second in the series with an inderterminate number of parts.
Carl Sagan’s Pale Blue Dot tells us a lot more about our place in the Cosmos than any creation myth cooked up by men. The reality of how stars and worlds are born makes the primitive explanations of our ancestors pale in comparison. The fact that no scripture holds a description of the creation of the Earth that comes even vaguely close to the reality we have discovered speaks volumes as the origins of these texts. They do not contain the facts because the facts are beyond the comprehension and imagination of the human brain.
