Pluto's lowered celestial status will probably stick at an upcoming meeting of astronomers in Rio de Janeiro, an American astronomer predicted Sunday. Pluto was reduced from a full-fledged planet -- the ninth in the Earth's solar system -- to dwarf planet at a meeting of the International Astronomical Union three years ago in Prague, Czech Republic. The Houston Chronicle reported Stephen Maran, co-author of the recent book Pluto Confidential, says politics may keep the only planet discovered...

NEW YORK -- Pluto was once a planet. Then, a dwarf planet. And as of last week, a plutoid. The fall from grace has teachers, parents and educational publishers struggling to keep up, while kids remain loyal to their favorite, the ninth planet. Underscore planet. Last week, the International Astronomical Union (IAU) announced Pluto should now be called a "plutoid," two years after the organization voted to demote Pluto to "dwarf planet" status. Meanwhile, many kids are nearly...

The New Horizons team got a faint glimpse of the mission's distant, main planetary target when one of the spacecraft's telescopic cameras spotted Pluto for the first time. The Long Range Reconnaissance Imager (LORRI) took the pictures during an optical navigation test on Sept. 21-24, and stored them on the spacecraft's data recorder until their recent transmission back to Earth. Seen at a distance of about 4.2 billion kilometers (2.6 billion miles) from the spacecraft, Pluto is little more...

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 Bill Trott WASHINGTON (Reuters) - The American astronomer who put Pluto on the solar system map would have accepted its demotion to non-planet status because he was a good scientist, his widow said on Thursday. "Clyde said, 'Well, it's there. You can do what you want with it,"' Patricia Tombaugh, 94, said from her home in Las Cruces, New Mexico, after the International Astronomical Union downgraded husband Clyde Tombaugh's crowning achievement. Tombaugh was 24 years old and...

CAPE CANAVERAL, Fla. -- An unmanned NASA spacecraft the size and shape of a concert piano hurtled toward Pluto on Thursday on a 3-billion-mile journey to the solar system's last unexplored planet - a voyage so long that some of the scientists who will be celebrating its arrival are still in junior high. The New Horizons spacecraft blasted off aboard an Atlas V rocket in a spectacular start to the $700 million mission. Though it is the fastest spacecraft ever launched, capable of reaching...

Flagstaff, AZ -- The planet Pluto turns 75 this month. Clyde Tombaugh discovered the ninth planet in the solar system on the afternoon of February 18, 1930 while he meticulously examined a pair of deep sky photographs at Lowell Observatory.  Tombaugh exposed the photographs on two nights in late January using the Observatory's 13-inch Abbott Lawrence Lowell Telescope. Then, as part of the carefully planned and executed planet search, Tombaugh "blinked" the two exposures using a machine...

Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
