Sep 14 – 2B03 14/09/2011 9:23:00 AM Gas planets  No solid surface – huge thick layer of clouds  may have solid or liquid cores Pluto does have a solid surface Jupiter – biggest planet  64 moons (satellites [miniature solar systems]) as of now  Bands - cloud patterns – they rotate with the planet o The great red spot – giant hurricane (much longer lived than any hurricane on earth, approx. 400 years) – trapped by bands of clouds  4 famous moons – Galilean Moons o Io is one of them  Geologically very active – covered in volcanoes o Europea – one of the places in the solar system that can potentially hold life – has an ocean that may have life o Discovered by Galileo (one of the first observers)  He could see with his rudimentary telescope Saturn – beautiful rings  2 ndbiggest  one of the moons of saturn - Titan - another possible home of life (mars, Europa, and this moon – titan)  the material that goes into the rings – a failed moon – because of the strong gravity – it has been broken up into this disc of this material – a thin disk is the most stable of configurations How did the rings form:  Small moons that come together that broke up, and others that did not form (other matter) Uranus and Neptune – outermost planets  Neptune has a large storm (kinda like the great red storm) Mars and Jupiter - between them lies the asteroid belt  Gravity of Jupiter prevented the material from forming a planet – that’s why the astrioids stay there (together, lots of them) o the largest of the asteroids between mars and Jupiter is Ceres – and it is now considered a dwarf planet  normally, its planet then space (nothing), then planet. If Jupiter was a little bigger, it could might have been a star -> it is very common to have a system with 2 stars (binary system) / 50/50 chance it’s a binary system Other solar systems have the big planets close to the sun, and we have the opposite.
