- Ceres is the only dwarf planet in the inner Solar System and is the largest asteroid in the asteroid belt between Mars and Jupiter.
- Engineers operating the NASA’s Dawn spacecraft have initiated maneuvers that will bring the satellite to the lowest and final orbit over the planet Ceres.
The general form of a planet's or a comet's orbit depends on its eccentricity, which is the measurement of the orbit's deviation from circularity. A circle's eccentricity is 0, and the eccentricity of a parabola is 1. NASA's Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000 kilometers) from Ceres when it was captured by the dwarf planet's gravity at about 4:39 a.m.

Summary[edit]
Description | English: The diagram illustrates the orbits of Ceres (blue) and several planets (white/grey). The segments of orbits below the ecliptic are plotted in darker colours, and the orange plus sign is the Sun's location. The top left diagram is a polar view that shows the location of Ceres in the gap between Mars and Jupiter. The top right is a close-up demonstrating the locations of the perihelia (q) and aphelia (Q) of Ceres and Mars. Interestingly, the perihelia of Ceres (as well as those of several other of the largest MBAs) and Mars are on the opposite sides of the Sun. The bottom diagram is a perspective view showing the inclination of the orbit of Ceres compared to the orbits of Mars and Jupiter. Deutsch: Das Diagramm illustriert die Umlaufbahnen der Ceres (blau) und mehrerer Planeten (weiß/grau). Die Abschnitte der Umlaufbahnen unter der Ekliptik sind in dunkleren Farben dargestellt und die orangenen Plus-Zeichen bezeichnen die Position der Sonne. Das Diagramm links oben ist eine polare Sicht der Periapsis, die die Position der Ceres in der Lücke zwischen Mars und Jupiter zeigt. Das Diagramm rechts oben ist eine Nahaufnahme, die die Positionen der Periapsis (q) und der Apoapsis (Q) der Ceres und des Mars zeigen. Interessanterweise ist die Periapsis der Ceres (wie auch die mehrerer anderer der größten MBAs) und des Mars auf der gegenüberliegenden Seite der Sonne. Das untere Diagramm ist eine perspektivische Sicht, die die Inklination der Umlaufbahn der Ceres mit den Umlaufbahnen des Mars und des Jupiter vergleicht. Français : Ce schéma montre les orbites de la planète naine(1) Cérès (bleu) et de certaines autres planètes du système solaire (vert et gris). La partie de chaque orbite située sous le plan de l'écliptique est affichée d'une couleur plus sombre ; la croix orange représente la position du Soleil. |

Facts about the Dwarf Planet Ceres
- Ceres was the first object considered to be an asteroid.
Italian astronomer Giuseppe Piazzi discovered and named Ceres in early 1801. - The first visit to Ceres is due in 2015.
NASA’s Dawn spacecraft has been making its way to Ceres from the asteroid Vesta since September 2012. There is high interest in this mission since Ceres will be the first Dwarf Planet visited by a spacecraft and is one possible destination for human colonisation given its abundance of ice, water, and minerals. - Ceres has a mysterious white spot.
This can be seen in both the old Hubble images and the more recent photos taken by the Dawn spacecraft on its approach. - Every second Ceres loses 6kg of its mass in steam.
Plumes of water vapour shooting up from Ceres’ surface were observed by the Herschel Space Telescope this was the first definitive observation of water vapour in the asteroid belt. It’s thought this is caused when portions of Ceres’ icy surface warm. - Ceres accounts for one third of the mass in the asteroid belt.
Despite this it is still the smallest and least massive of the dwarf planets. - For roughly the first 50 years after its discovery Ceres was frequently referred to as a planet.
By the end of 1851 14 other similar objects had been discovered and it did not take long before these instead became known as “minor planets”. Ceres was eventually reclassified as a Dwarf Planet alongside Pluto in 2006. - Ceres is the only dwarf planet with no moons.
The other dwarf planets; Pluto, Haumea, Makemake and Eris all have at least one moon.
