The International Astronomical Union has decided on the term plutoid as a name for dwarf planets like Pluto at a meeting of its Executive Committee in Oslo.
For those of you who are not geophysicists with four decades of service to the cause, Vesta is the brightest asteroid in the night's sky and the only one visible from Earth to the naked eye.
NASA's Dawn spacecraft successfully completed the first test of its ion propulsion system over the weekend. The system is vital to the success of Dawn's 8-year, 1.6 billion-kilometer (3-billion-mile) journey to asteroid Vesta and dwarf planet Ceres.
NASA's Dawn spacecraft rocketed away Thursday toward an unprecedented double encounter in the asteroid belt. Dawn's mission is the world's first attempt to journey to a celestial body and orbit it, then travel to another and circle it as well.
Launch and flight teams are in final preparations for the planned Sept. 27 liftoff from Pad 17-B at Cape Canaveral Air Force Station, Fla., of NASA's Dawn mission. The Dawn spacecraft will venture into the heart of the asteroid belt.
In the Star Wars movies, fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models begin to describe an even wider range of Earth-size planets that astronomers might actually be able to find in the near future.
The Dawn spacecraft completed the 25-kilometer (15-mile) journey from Astrotech Space Operations in Titusville, Fla., to Pad-17B of the Cape Canaveral Air Force Station at 5:10 a.m. EDT today. The launch period for Dawn, NASA's eight-year, more than 5-billion-kilometer (3.2-billion-mile) odyssey into the heart of the asteroid belt, opens Sept. 26.
Uranus' moon Titania -- Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel.

Titania was named after Titania, the Queen of the Faeries in A Midsummer Night's Dream. Titania is composed of roughly 50% water...
Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
