WASHINGTON (Reuters) - A distant object named Buffy has been spotted circling the sun far beyond Neptune in a strange tilted orbit that is making some astronomers question how the outer reaches of the solar system formed. Officially called 2004 XR 190 by the International Astronomical Union but code-named Buffy, the object is now about 58 times as far from the sun as Earth, and twice as far from the sun as Neptune. At this distance from the heart of the planetary system, Buffy is a considered...

By Deborah Zabarenko WASHINGTON (Reuters) - Pluto, that cosmic oddball at the far reaches of our solar system, may have three moons instead of one, scientists announced on Monday. Astronomers using the Hubble Space Telescope glimpsed the two new satellites back in May, and were intrigued when the pair of possible moons appeared to move around Pluto over three days in what looked like a nearly circular orbit. If confirmed by the International Astronomical Union, they will get...

NASA -- Using NASA's Hubble Space Telescope to view the ninth planet in our solar system, astronomers discovered Pluto may have not one, but three moons. If confirmed, the discovery of the two new moons could offer insights into the nature and evolution of the Pluto system; Kuiper Belt Objects with satellite systems; and the early Kuiper Belt. The Kuiper Belt is a vast region of icy, rocky bodies beyond Neptune's orbit. "If, as our new Hubble images indicate, Pluto has not one, but two or...

LOS ANGELES (AP) - The discovery of a new planetoid has set off a bitter feud between American and Spanish scientists while raising questions about the ethics of Internet research. The dispute began in July when Michael Brown, a professor at the California Institute of Technology in Pasadena, discovered a new planetoid in the solar system known as the Kuiper Belt. Days before announcing his discovery, however, a group of Spanish astronomers claimed the new planetoid. American researchers...

By Deborah Zabarenko WASHINGTON (Reuters) - Xena, the possible 10th planet in our solar system, has its own moon, a dim little satellite called Gabrielle, its discoverers reported. Astronomers who reported Xena's discovery in July said they detected Xena's sidekick on September 10 using the Keck Observatory on Mauna Kea in Hawaii. Their findings will be submitted to the Astrophysical Journal Letters on Monday. "Since the day we discovered Xena, the big question has been whether or...

LOS ANGELES -- The astronomers who claim to have discovered the 10th planet in the solar system have another intriguing announcement: It has a moon. While observing the new, so-called planet from Hawaii last month, a team of astronomers led by Michael Brown of the California Institute of Technology spotted a faint object trailing next to it. Because it was moving, astronomers ruled it was a moon and not a background star, which is stationary. The moon discovery is important because it can...

NASA -- Comet Tempel-1 may have been born in the region of the solar system occupied by Uranus and Neptune today, according to one possibility from an analysis of the comet's debris blasted into space by NASA's Deep Impact mission. If correct, the observation supports a wild scenario for the solar system's youth, where the planets Uranus and Neptune may have traded places and scattered comets to deep space. "Our observation is a definitive investigation revealing the composition of comet...

Astrobiology Magazine -- When planetary scientists announced on July 29 that they had discovered a new planet larger than Pluto, the news overshadowed the two other objects the group had also found. But all three objects are odd additions to the solar system, and as such could revolutionize our understanding of how our part of the celestial neighborhood evolved. To the discoverers, the objects still go by the unofficial code-names "Santa," "Easterbunny," and "Xena," though they are...

NASA -- New NASA Hubble Space Telescope images of the distant planet Neptune show a dynamic atmosphere and capture the fleeting orbits of its satellites. The images have been assembled into a time-lapse movie revealing the orbital motion of the satellites. Images were taken in 14 different colored filters probing various altitudes in Neptune's deep atmosphere so that scientists can study the haze and clouds in detail. These are several snapshots from the Neptune movie. The natural-color view...

By Gina Keating LOS ANGELES (Reuters) - A California astronomer has discovered what he believes is the 10th planet in our solar system, a group of NASA-funded researchers said on Friday. The new planet, known as 2003UB313, has been identified as the most distant object ever detected orbiting the sun, California Institute of Technology astronomer Michael Brown said. Brown and colleagues Chad Trujillo and David Rabinowitz have submitted a name for the planet to the International...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...

Quaoar -- Quaoar ("kwah-oh-ahr", /kwA o Ar/) is a Trans-Neptunian object circling the Sun in the Kuiper belt, discovered in 2002 by astronomers Chad Trujillo and Mike Brown at the California Institute of Technology in Pasadena, California. Quaoar is estimated to have a diameter of about 1,280 kilometres, which would make it the largest Solar System object discovered since Pluto and, indeed, the largest known minor planet. Larger than all the asteroids put together, it is about one...

Oort Cloud -- The Oort cloud is a postulated cloud of comets situated about 50,000 to 100,000 AU from the sun. Although no direct observations have been made of such a cloud, it is believed to be the source of most or all comets entering the inner solar system (some short-period comets may come from the Kuiper belt), based on observations of the orbits of comets. The Oort cloud was proposed in 1950 by Dutch astronomer Jan Oort to explain an apparent contradiction: comets are destroyed...
