By Andy Sullivan WASHINGTON (Reuters) - Hundreds of U.S. scientists have challenged a recent decision by an international astronomy group to strip Pluto of its planetary status with a petition rejecting its definition of what constitutes a planet. The astronomical insurrection shows that debate is likely to continue over the status of the icy rock at the edge of the solar system that was considered the ninth planet until a vote last week by the International Astronomical Union. Petition...

WASHINGTON (AP) - "My Very Excellent Mother Just Sent Us Nine Pizzas." That and variations on it are the way millions of people learned to remember the names of the planets in the solar system - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. The problem is that an international convention of astronomers decreed Thursday that tiny Pluto no longer meets the definition of a planet. What a way to spoil a good mnemonic. Now how will students learn the planets? Some...

By Donna Smith WASHINGTON (Reuters) - Pluto's lost status disappointed some schoolchildren and had space museum curators scrambling but in the words of one teenager, "It's one less planet to memorize." Quinn Huebner, 15, was visiting the Smithsonian Institution's National Air and Space Museum on Thursday when he and his family from Mazomanie, Wisconsin, learned international astronomers had decided Pluto was no longer a planet. His sister Grace, 11, also voiced relief. Had Pluto...

By Alan Crosby PRAGUE (Reuters) - Pluto was stripped of its status as a planet on Thursday when astronomers from around the world redefined it as a "dwarf planet," leaving just eight major planets in the solar system. With one vote, toys and models of the solar system became instantly obsolete, forcing teachers and publishers to scramble to update textbooks and lessons used in classrooms for decades. "Pluto is dead," Mike Brown of the California Institute of Technology bluntly told...

By Alan Crosby PRAGUE (Reuters) - Pluto was stripped of its status as a planet on Thursday when astronomers from around the world redefined it as a "dwarf planet," leaving just eight classical planets in the solar system. Discovered in 1930, Pluto has traditionally been considered the ninth planet, and furthest from the sun, in the solar system. However, the definition of a planet approved after a heated debate among some 2,500 scientists from the International Astronomical Union...

PRAGUE (Reuters) - Scientists from around the world on Thursday approved a new definition of a planet, downgrading Pluto's status to leave just eight classical planets. After a heated debate, 2,500 scientists and astronomers voted at the International Astronomers Union General Assembly that Pluto, which has been called a planet since being discovered in 1930, would be put into a category of planets called "dwarf planets."

By Alan Crosby PRAGUE -- In coming up with the definition of a planet, astronomers hoped to bring order to the way we look at solar systems. Instead, they created a big bang of their own. A committee formed by the International Astronomers Union (IAU) has proposed that to be called a planet, a celestial body must be in orbit around a star while not itself being a star. It also must be large enough in mass for its own gravity to pull it into a nearly spherical shape. The new definition -- the...

By Alan Crosby PRAGUE -- Learning the planets of our solar system is about to become more difficult for school children around the world. The International Astronomers Union (IAU) put forward a definition of a planet on Wednesday that will expand the number from nine to 12, and create different categories of planets in a nod to technological advances that allow astronomers to look deeper into space. In defining for the first time what exactly a planet is, a seven member committee of the IAU...

By Alan Crosby PRAGUE (Reuters) - The question of whether Pluto is a real planet, hotly debated by scientists for decades, came to a head on Wednesday when the global astronomers' body proposed a definition of a planet that raises their number to 12 from nine. The definition set out by a committee of the International Astronomers Union (IAU) answers the key question: How small can a body be and still be called a planet? in a way that leaves Pluto's status intact -- but modified....
