Counting planets does encourage clever mnemonics, such as "my very Educated Mother Just Served Us Nine pizzas"—or its likely successor: "my very Educated Mother Just Served Us noodles." Or Nectarines. It could be argued that such counting exercises have stunted the curiosity of an entire generation of children. Counting and memorizing just stands in the way of appreciating the full richness of our cosmic environment, right? On the other hand, it's well known that the concreteness of lists and lyrics helps students tie abstract concepts to tangible learning tools. The best solution probably rests in the middle ground. For now, a dwarf planet is defined as a solar System body that orbits the sun, is near-spherical in shape, isn't a satellite, and shares the region around its orbit with other celestial bodies.

Since Pluto qualifies, this would have given everyone the right to place Pluto and Jupiter in the same category, even though Jupiter is 250,000 times larger. The draft resolution would also have rendered at least three additional objects eligible for planet status, objects that had achieved hydrostatic equilibrium but had previously been deemed "too small." so for that one week in 2006, there were 12 planets. The iau's roundness criterion added Ceres, the largest asteroid; Pluto's moon Charon, which is unusually large relative to Pluto; and another kuiper Belt object, 2003 UB313, affectionately dubbed Xena after the leather-clad warrior princess from cable television, but now officially named Eris, after the Greek. Plutophiles had about a week to rejoice before the astronomers refined their definition: a planet must also be the most massive object in its orbital zone. Poor Pluto is crowded by thousands of other icy bodies in the outer Solar System, some bigger than Pluto itself, so it fails the test. This criterion also eliminated Ceres, Charon, and Eris. To soothe the Pluto boosters, the iau elected to call it a dwarf planet, without clearly qualifying what that. And Then There were eight In 2006, the International Astronomical Union published a draft illustration of the solar System containing 12 planets (bottom). One week later, a final illustration was published (top with four of those objects reclassified as "dwarf planets." iau how much good should counting count? So today we're officially back to eight planets—the nine we memorized in grade school, minus Pluto.

The kuiper Belt, a disk-shaped region of icy debris beyond the orbit of Neptune, the kuiper Belt likely contains remnants of the early. Solar, system, as does the asteroid business belt. Because many asteroids and comets never formed planetary bodies that melted, they record early. Solar System processes—a record that has been erased elsewhere. Nasa/jhu so we find ourselves at the International Astronomical Union General Assembly, meeting in Prague in August 2006. At first the iau seemed ready to defend Pluto's planetary standing. On August 16, after many meetings over the course of a year, its seven-member Planet Definition Committee stated that round objects in orbit around the sun are planets. Roundness (though not necessarily a perfectly spherical shape reasoned the committee, indicated a balance between the gravitational forces pulling matter inward and the internal pressure pushing outward within a celestial body: a scientifically significant state called hydrostatic equilibrium.

Jewitt of the University of Hawaii and Jane luu of the massachusetts Institute of Technology began to detect a swath of frozen objects on the. Solar, system 's fringes, out beyond Neptune. This region of icy bodies was named the kuiper Belt in honor of the dutch-born American astronomer Gerard kuiper, who predicted its existence. Pluto is one of its largest members.

Planetfall: New Solar System Visions

With the discovery of dozens more, however, it became clear that this new community of objects deserved its own classification. Astronomers called these small bodies made of rock and minerals asteroids, and have now cataloged tens of thousands of them. Even the traditional planets don't fit into one neat category. The rocky planets (Mercury, venus, earth, and Mars) form a family because they are relatively small and rocky, while the gassy planets (Jupiter, saturn, Uranus, and Neptune) are large, gaseous, have many moons, and bear rings. The number of planets dropped to six when writing the sun and the moon were deleted and Earth was added. When Uranus was found in 1781, the figure rose to seven again. It was bumped up to 11 with the discovery of the four largest bodies in the zone between Mars and Jupiter.

Then it dropped back bullying to seven again after these four bodies—along with others in the zone yet to be discovered—were demoted to asteroids. Once neptune was spied in 1846, the total became eight. When astronomer Clyde tombaugh found Pluto in 1930, after a dogged search for a long-suspected Planet X beyond Neptune, the tally rose to the now-familiar nine. But refined measurements showed the object to be much, much smaller than originally thought: smaller, in fact, than six of the satellites in the. Solar, system, including Earth's moon. The kuiper Belt thickens the plot. The story took another twist in 1992, when david.

Life got more complicated in 1543, when Nicolaus Copernicus described a newfangled. In his heliocentric universe, instead of remaining stationary in the center, earth moved around the sun, just like the other bodies. At that moment, planet lost its astronomical meaning. Astronomers tacitly agreed that whatever orbits the sun is a planet and whatever orbits a planet is a moon. Evolving Our Understanding, petrus Apianus's Earth-centric engraving of the.


Solar, system (left) from 1540 shows the planets and the sun orbiting Earth, with a band of constellations around the perimeter. In 1543, copernicus's revolutionary heliocentric system (center) paved the way for modern astronomy, including way-finding diagrams like the plaque (which includes Pluto) on the pioneer 10 spacecraft (right now heading into interstellar space. This wouldn't be a problem if cosmic discoveries had ended with Copernicus. But shortly thereafter, we learned that comets, too, orbit the sun and are not local atmospheric phenomena, as was long believed. Comets are icy objects on elongated orbits that throw off a long tail of gases as they near the sun. Are they planets too? How about the chunks of rock and metal that orbit the sun between Mars and Jupiter in the asteroid belt? When Ceres, the first such object, was detected by giuseppe piazzi in 1801, everyone called it a planet.

The word planet seems to hold an irrational sway over our hearts and minds. That made sense in the days when, along with stars, they were the only familiar objects in space—before telescopes could observe the birth of distant galaxies, before space probes had bulldozed into a comet, and before we understood the history of cosmic collisions that links. In these past four weeks, we've looked at the. Solar, system as scientists do: at its structure gps and composition, its origin, and its contents, rocky and gassy. Let's look at Pluto once again—not in terms of rigid classification or nursery-school mnemonics but in the context of its scientific importance—and at how learning more about writing Pluto contributes to the human endeavor of understanding the cosmos. What's a planet, anyway? All the, sturm und Drang about Pluto stems from a simple problem. The label planet originated in ancient Greece. The word simply meant "wanderer" and referred to the seven prominent celestial objects—Mercury, venus, mars, jupiter, saturn, the sun, and the moon—that moved against the background of stars.

is just right for water to exist as a liquid: get in as close venus and the water just boils away as steam, while as far out as the orbit of Mars water is frozen to ice. Soon after the birth of earth, it was a very different place from the one we know today. Its air was made of the unbreathable and. Okay, everyone, it's official. Pluto is not a planet. As decreed in August 2006 by a vote of the general Assembly of the International Astronomical Union (iau pluto is now a "dwarf planet." On the other hand, who does the iau think it is—indeed, who do we astronomers think we are—to be able. Isn't that sort of like california declaring that liechtenstein isn't a country?

Earth, if you approached the. Solar, system from space, one planet would stand out as very odd. The third world from the sun is brightly coloured, in shades of mainly blue, with patches of red and green, and constantly shifting patterns of white cloud. And it has an unusually large moon; which-by contrast- is dull and uniformly brown. The perfect paper planet, come closer, and you find blue is liquid water. This is the only rocky planet with water. Test the atmosphere, and again this planet is unique: the air contains a lot of reactive gas oxygen. And finally, take a closer look at the green areas.

Solar, system, humans live on a guaranteed small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earths neighbourhood and the planets Mercury, venus, mars, jupiter, saturn, Uranus, neptune and Pluto are the earths neighbours. They all have the same stars in the sky and orbit the same sun. Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and gas to collapse in on itself. The hot, central part of the cloud became the sun, while some smaller pieces formed around it and became the planets. Other fragments became asteroids and comets, show more content, future manned expeditions could melt the ice into water, for drinking, washing and turning into rocket-fuel: there is enough ice to make a lake 10km across and 10m deep.
