Link to How the universe works: 6- Extreme planets documentary
Documentary Description
There are just eight planets in our solar system, but there could be a
hundred billion in our Milky Way galaxy alone. As we enter into a golden
age of planetary discovery the possibilities are endless. Pushing out
deep into space we are finding planets that are stranger than we could
ever have imagined - from giant burning gas spheres to icy orphaned
worlds wandering in interstellar space. So just how did they get to be
so different? How the Universe Works follows the remarkable journey of
planets as they grow from grains of dust to the magnificently diverse
worlds we see today.
