Latest Dwarf planet Stories
After successfully completing nearly five months scrutinizing the giant asteroid Vesta at its lowest orbit altitude, NASA's Dawn spacecraft will begin its final major science data-gathering phase at Vesta on June 15.
Findings from NASA's Dawn spacecraft reveal new details about the giant asteroid Vesta, including its varied surface composition, sharp temperature changes and clues to its internal structure.
NASA's Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta on Monday, Dec. 12, beginning a new phase of science observations.
Vesta appears in a splendid rainbow-colored palette in new images obtained by NASA's Dawn spacecraft. The colors reveal Vesta to be a world of many varied, well-separated layers and ingredients.
Glide over the giant asteroid Vesta with NASA's Dawn spacecraft in a new 3-D video. Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements.
The European Southern Observatory announced on Wednesday that astronomers have accurately measured the diameter of the dwarf planet Eris for the first time.
Scientists with NASA's Dawn mission are sharing with other scientists and the public their early information about the southern hemisphere of the giant asteroid Vesta.
At this very moment one of the fastest spacecraft ever launched -- NASA's New Horizons -- is hurtling through the void at nearly one million miles per day.
Uranus' moon Titania -- Titania is the largest moon of Uranus. Titania was discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus, Oberon, Titania, Ariel and Umbriel, were given by John Herschel, the son of William. 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...
