Latest Kuiper belt Stories
Scientists have discovered that a dwarf planet at the edge of the solar system, dubbed 2007 OR10, is an icy world with about half its surface covered in water ice that once flowed from ancient, slush-producing volcanoes.
The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic elements.
In the outer reaches of our solar system lies a mysterious region far more remote and difficult to explore than the Australian outback.
The extraterrestrial rock is tumbling through space alongside thousands of similar objects in our solar system's main asteroid belt, roughly between the orbits of Mars and Jupiter.
The 1,000 objects so far directly imaged in the Kuiper Belt â€“ that swath of icy bodies circling around the sun with Pluto â€“ appear to be a wide range of colors: red, blue, and white.
New research by a University of Victoria PhD student is challenging popular theory about how part of our solar system formed.
New supercomputer simulations tracking the interactions of thousands of dust grains show what the solar system might look like to alien astronomers searching for planets.
GREENBELT, Md., Sept. 23 /PRNewswire-USNewswire/ -- New supercomputer simulations tracking the interactions of thousands of dust grains show what the solar system might look like to alien astronomers searching for planets.
Until now, astronomers have used telescopes to find Kuiper Belt objects (KBOs), moon-sized bodies, and obtain their spectra to determine what types of ices are on their surface.
According to the first ever infrared analysis of the atmosphere of Neptune's moon Triton, summer is in full swing in its southern hemisphere.
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...
