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/Best0fSciencehttp://www.youtube.com/ScienceTVhttp://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 .

In this short explainer video, Universe Today publisher Fraser Cain explains just how many planets there are in the Solar System. How did we go from 9 to 8, and what does this mean for Pluto? http://www.universetoday.com/15568/how-many-planets-are-in-the-solar-system/ --------------- How Many Planets are in the Solar System? I'm just going to warn you, this is a controversial topic. Some people get pretty grumpy when you ask: how many planets are in the Solar System? Is it eight, ten, or more? I promise you this, though, we're never going back to nine planets... ever. When many of us grew up, there were nine planets in the Solar System. It was like a fixed point in our brains. As kids, memorizing this list was an early right of passage of nerd pride: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. But then in two-thousand-five, Mike Brown discovered Eris, an icy object thought to be about the same size as Pluto, out beyond its orbit. That would bring the total number of planets to ten. Right? There's no turning back, textbooks would need to be changed. In order to settle the dispute, the International Astronomical Union met in two-thousand-six, and argued for, and against Pluto's planethood. Some astronomers advocated widening the number of planets to twelve, including Pluto, its moon Charon, the Asteroid Ceres, and the newly discovered Eris. In the end, they changed the definition of what makes a planet, and sadly, Pluto doesn't make the cut: Here are the new requirements of planethood status: 1. A planet has to orbit the Sun. Okay fine, Pluto does that. 2. A planet needs enough gravity to pull itself into a sphere. Okay, spherical. Pluto's fine there too. 3. A planet needs to have cleared out its orbit of other objects. Uh oh, Pluto hasn't done that. For example, planet Earth accounts for a million times the rest of the material in its orbit, while Pluto is just a fraction of the icy objects in its realm. The final decision was to demote Pluto from planet to dwarf planet. But don't despair, Pluto is in good company. There's Ceres, the first asteroid ever discovered, and the smallest of the dwarf planets. The surface of Ceres is made of ice and rock, and it might even have a liquid ocean under its surface. NASA's Dawn mission is flying there right now to give us close up pictures for the first time. Haumea, named after the Hawaiian goddess of fertility, is about a third the mass of Pluto, and has just enough gravity to pull itself into an ellipsoid, or egg shape. Even though it's smaller, it's got moons of its own. Makemake, a much larger Kuiper belt object, has a diameter about two-thirds the size of Pluto. It was discovered in two-thousand-five by Mike Brown and his team. So far, Makemake doesn't seem to have any moons. Eris is the most massive known dwarf planet, and the one that helped turn our definition of a planet upside-down. It's twenty-seven-percent more massive than Pluto and the ninth most massive body that orbits the Sun. It even has a moon: Dysnomia. And of course, Pluto. The founding member of the dwarf family. Want an easy way to remember the eight planets, in order? Just remember this mnemonic: my very excellent mother just served us noodles. For all you currently writing angry tweets to Mike Brown, hold on a sec. Changing Pluto's categorization is an important step that really needed to happen. The more we discover about our Universe, the more we realize just how strange and wonderful it is. When Pluto was discovered eighty years ago, we never could have expected the variety of objects in the Solar System. Categorizing Pluto as a dwarf planet helps us better describe our celestial home. So, our Solar System now has eight planets, and five dwarf planets. Thanks for watching!

http://facebook.com/ScienceReason ...Hubble's Universe Unfiltered (Episode 7): Eye Spy A Planet (Part 1/2) - Our Solar System. Up until the 1990s, we only knew of the planets in our own solar system. Since then, we have discovered over 300 planets orbiting other stars (extrasolar planets, exoplanets). However, most of these planets were found when scientists observed the effect of the planet's gravity upon their host stars. Astronomers could not show the world what we wanted most: a visible light picture of a planet around a star like the Sun. That situation changed in November 2008 with a discovery by the Hubble Space Telescope. Join us for the story that begins a new era in our knowledge of planetary systems. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fSciencehttp://www.youtube.com/ScienceTVhttp://www.youtube.com/FFreeThinkerhttp://www.youtube.com/RationalHumanism --- Hubble press release: Hubble Directly Observes Planet Orbiting Fomalhaut http://hubblesite.org/newscenter/archive/releases/2008/39/ --- Notes - Note that Hubble's discovery of Fomalhaut b is billed as the "first visible-light snapshot of a planet orbiting another star." It is important to note that the first direct detection of a planet will likely turn out to be the planet known as 2M1207 b. However, the host, 2M1207, is not a full-fledged star, but a brown dwarf (see below). In addition, pictures of three planets around HR 8799, released the same day as the Fomalhaut discovery, were taken in the infrared. - Let me clarify about 2M1207. It has less than 3% the mass of our Sun, roughly 25 times the mass of Jupiter. That mass places it in the brown dwarf category: large enough to ignite deuterium fusion in its core (thus not a planet), but not large enough for hydrogen fusion (thus not a star). Brown dwarfs glow faintly at formation and then spend the rest of their lives cooling and fading away. Brown dwarfs are generally thought to be those objects with between 15 and 70 times the mass of Jupiter. - I wanted to make a joke that what the Hubble image of Fomalhaut looked most like is the "Eye of Sauron" from the "Lord of the Rings" movies. However, New Line Cinema did not respond to my requests for permission, and my producer would not let me use the image in the podcast. That joke is one reason why the episode is called "Eye Spy." - A betting astronomer might have chosen Beta Pictoris as the first star around which a planet would have been seen. We have been getting intriguing evidence that planets should be there for more than a decade. However, since the disk in the Beta Pic system is roughly perpendicular to our line of sight, any planets will travel in front of and behind the star from our point of view. Hence, we could only observe them well during parts of their orbits. Face-on systems, like HR 8799, are much more favorable for direct images. - If confirmed, the Beta Pictoris planet would indicate that giant planets can form quickly. Beta Pictoris is about 12 million years old. We believe that giant planets must form within the first 10 or so million years of a developing system, as winds and radiation from newborn stars should remove the gas from the system on that timescale. A giant planet needs to accrete some of that gas during its formation, and thus must form in millions of years. In contrast, it is thought that Earth may take as much as a couple hundred million years to form. • http://hubblesite.org/ --- Hubble's Universe Unfiltered is a collection of video podcasts.
