The images of Ceres were taken on 4th February 2015 from a distance of about 90,000 miles (145,000 kilometres).
At a resolution of 8.5 miles (14 kilometres) per pixel, the pictures represent the sharpest images to date of Ceres.This animation showcases a series of images obtained with the Framing Camera of NASA’s Dawn spacecraft on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet. The resolution is 8.5 miles (14 kilometers) per pixel. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDAAfter the spacecraft arrives and enters into orbit around the dwarf planet, it will study the intriguing world in great detail. Ceres, with a diameter of 590 miles (950 kilometres), is the largest object in the main asteroid belt, located between Mars and Jupiter.
Many of you may have tracked down an asteroid with binoculars or a telescope, but have you ever seen one with the naked eye? If not, then June presents you with an opportunity to see the brightest, 4 Vesta, at a close opposition. What’s more, ringed planet Saturn lies close by to act as a convenient guide.
A four-planet system orbiting the star Kepler-223 in the constellation Cygnus is actually a rarity: Its planets, all miniature Neptunes nestled close to the star, are orbiting in a unique resonance that has been locked in for billions of years. For every three orbits of the outermost planet, the second orbits four times, the third six times and the innermost eight times.
NASA’s Mars Reconnaissance Orbiter (MRO) has detected deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, such deposits might provide a delicate window into the possibility of past life on the Red Planet.
