Pluto Demoted From Planetary Status Five Years Ago Today
2012-08-24 12:54:31

Lawrence LeBlond for redOrbit.com - Your Universe Online On August 24, 2006, the solar system´s most distant family member -- tiny, isolated icy planet Pluto -- received some shocking news: it would no longer be considered a true planet. The ruling spurred a hotbed of controversy, with many experts disagreeing with Pluto´s new status as a “dwarf planet.” Despite the controversy and oppositions from scientists and laypeople alike, the ruling went through, reducing...

Lee Rannals for redOrbit.com - Your Universe Online Scientists announced on Wednesday they have discovered the smallest moon yet, orbiting around the dwarf planet Pluto. The discovery was made by a team of scientists who used the Hubble Space Telescope to scout out Pluto's neighborhood ahead of a NASA spacecraft that is scheduled to arrive in 2015. The new moon, known as P5 currently, appeared as a small fleck in the Hubble images, and scientists believe it is about 6 to 15 miles...

Fifth Moon Orbiting Pluto Discovered By Hubble
2012-07-11 20:53:03

A team of astronomers using NASA´s Hubble Space Telescope is reporting the discovery of another moon orbiting the icy dwarf planet Pluto. The moon is estimated to be irregular in shape and 6 to 15 miles across. It is in a 58,000-mile-diameter circular orbit around Pluto that is assumed to be co-planar with the other satellites in the system. “The moons form a series of neatly nested orbits, a bit like Russian dolls,” said team lead Mark Showalter of the SETI Institute...

Scientists Analyze Tiny Comet Grain To Date Jupiter's Formation
2012-03-02 04:12:19

Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System. The new finding helps test Solar System formation theories, which do not agree on the timing of Jupiter though it is certain the formation of this giant planet affected how materials moved, collided, and coalesced during the complex planet-forming process. Published in the February 1, 2012...

NASA´s New Horizons mission reached a special milestone Friday, Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft. It´s taken New Horizons 2,143 days of high-speed flight — covering more than a million kilometers per day for nearly six years–to break the closest-approach mark of 1.58 billion kilometers set by NASA´s Voyager 1 in January 1986. “What a cool milestone!” says New Horizons...

Solar System Ejected A Giant Planet 600 Million Years Ago
2011-11-11 06:10:42

According to a study published in The Astrophysical Journal Letters, our solar system may have ejected a giant planet from its orbit and spared the Earth. Experts wrote that Jupiter had helped eject another giant planet from our solar system when it was about 600 million years old. "We have all sorts of clues about the early evolution of the solar system," author Dr. David Nesvorny of the Southwest Research Institute said in a press release. "They come from the analysis of the...

Image 1 - Comet Found To Contain Ocean-Like Water
2011-10-05 14:10:47

According to a new study published in the journal Nature on Wednesday, the Earth's ocean may have been created by comets. Measurements taken from the Herschel Space Observatory show that comet Hartley 2 contains water with the same chemical signature as Earth's oceans. This comet lies in the Kuiper Belt about 30 to 50 times as far away as the distance between Earth and the sun. "Our results with Herschel suggest that comets could have played a major role in bringing vast amounts of...

Spinning Object Discovered In The Kuiper Belt
2011-10-03 09:07:55

[ Watch the Video ] The bizarre, hourglass-shaped Kuiper belt object 2001QG298 spins round like a propeller as it orbits the Sun, according to an astronomer from Queens University Belfast.   The discovery that the spinning object is tilted at nearly 90 degrees to the ecliptic plane is surprising, and suggests that this type of object could be very common in the Kuiper belt. The finding will be presented by Dr Pedro Lacerda at the Joint Meeting of the European Planetary Science...

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...

Solar System

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...
