This image is one of several NASA’s Dawn spacecraft took on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet.

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.
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.
Like its cousin the Kepler space telescope, NASA’s Dawn mission to the asteroids Vesta and Ceres has run out of gas, ending a remarkably successful 11-year mission to the two largest members of the asteroid belt.
Researchers using NASA’s Mars Reconnaissance Orbiter have determined that frozen beneath a region of cracked and pitted plains on the Red Planet there lies about as much water as fills Lake Superior, largest of the Great Lakes. Scientists examined part of Mars’ Utopia Planitia region with the orbiter’s ground-penetrating instrument, revealing a deposit more extensive in area than the state of New Mexico.
