http://www.facebook.com/ScienceReason ... Science@ESA (Episode 7): Exploring our backyard, the Solar System (Part 1)In this seventh episode of the Science@ESA vodcast series Rebecca Barnes continues to journey through the wonders of modern astronomy bringing us closer to home as we begin to explore the Solar System. We'll discover the scale and structure of the Solar System, find out why we explore it and introduce the missions launched on a quest to further investigate our local celestial neighbourhood.---Please SUBSCRIBE to Science & Reason:• http://www.youtube.com/Best0fScience• http://www.youtube.com/ScienceTV• http://www.youtube.com/FFreeThinker---The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars.Beyond Mars is the asteroid belt -- a region populated by millions of rocky objects. These are left-overs from the formation of the planets, 4.5 billion years ago.On the far side of the asteroid belt are the four gas giants - Jupiter, Saturn, Uranus and Neptune. These planets are much bigger than Earth, but very lightweight for their size. They are mostly made of hydrogen and helium.Until recently, the furthest known planet was an icy world called Pluto. However, Pluto is dwarfed by Earth's Moon and many astronomers think it is too small to be called a true planet.An object named Eris, which is at least as big as Pluto, was discovered very far from the Sun in 2005. More than 1,000 icy worlds such as Eris have been discovered beyond Pluto in recent years. These are called Kuiper Belt Objects. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as "dwarf planets".Even further out are the comets of the Oort Cloud. These are so far away that they are invisible in even the largest telescopes. Every so often one of these comets is disturbed and heads towards the Sun. It then becomes visible in the night sky.http://sci.esa.int/science-e/www/area/index.cfm?fareaid=7.

Sep 19, 2010 - The distances in space is just mind-boggling to me. Our solar system is vast and huge, however, when you consider that it's a part of the Milky Way, it's just a small part of an enormously vast galaxy... which in itself is just a very small part of the universe.

Nov 27, 2011 - The Sun is located inside the inner-arm of the Milky Way galaxy. It's15,000 light years from the galactic center and not part of a major spiraling arm. It's unclear how the sun moves about in space. If galactic centers are twirling stars in a spiral direction, the sun must also be moving in a spiral direction. Whether it moves about on its own, on its axis, is unknown.

Mar 30, 2012 - "Everyone is different", another quote from the religious kind. You think every kiddo should be allowed to show his 2 penny humor and encouraged even? No, that's not the way it should be, he should be showed at least a more mature attitude. Not the answer he's looking for in his ignorance. You bring the argument of so many religious people: "Leave me in my "fun" world, i don't need you to socialize with, i need only people who laugh at my silly jokes".

Mar 30, 2012 - You mean heavy elements, which don't exist in a star, are ejected from a star? Haha.

May 13, 2012 - which the hell are heavy elements? damn i hate you. being a pilot is frustrating i lnow only atmospheric composition and pres/temp standards and variations for the earth i wish i knew more chemestry and astronomy in general
