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.
NASA scientists are tracking the upcoming Halloween flyby of asteroid 2015 TB145 with several optical observatories and the radar capabilities of the agency’s Deep Space Network at Goldstone, California. Only discovered sixteen days ago, the 400-metre-wide asteroid will fly past Earth at a safe distance slightly farther than the Moon’s orbit on 31 October at 5:05pm GMT.
Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, currently drifting toward the British Isles at 17cm per year. These wobbles don’t affect our daily life, but they must be taken into account to get accurate results from GPS, satellites and observatories on the ground.
