Some notable observation milestones for Ceres include: An occultation of a star by Ceres was observed in Mexico, Florida and across the Caribbean on November 13, 1984. Features on Ceres' surface have been telescopically imaged several times in recent years. These include: Ultraviolet Hubble Space Telescope images with 50 km resolution taken in 1995 [8] [13]. Visible images with 60 km resolution taken with the Keck telescope in 2002 using adaptive optics [9]. Link to images here. The best resolution to date (30 km) visible light images using Hubble again ...

Pluto is the ninth planet in the solar system. Discovered in 1930 and immediately classified as a planet, its status is currently under dispute. Pluto has an eccentric orbit that is highly inclined in respect to the other planets and takes it inside the orbit of Neptune. Its largest moon is Charon, discovered in 1978; two smaller moons were discovered in 2005. Pluto's astronomical symbol is a P-L monogram, ♇. This represents both the first two letters of the name Pluto and the initials of Percival Lowell ...

Ceres was discovered by accident. Piazzi was searching for a star listed by Francis Wollaston as Mayer 87 because it was not in Mayer's zodiacal catalogue in the position given (it eventually transpired that Wollaston had made a mistake —the star was in fact Lacaille 87). Instead, Piazzi found a moving star-like object, which he thought at first was a comet. Piazzi observed Ceres a total of 24 times, the final time on February 11, when illness interrupted. On 24 January 1801, Piazzi announced his discovery in letters to fellow astro ...

Ceres was originally named Ceres Ferdinandea after both the mythological figure Ceres (Roman goddess of plants and motherly love) and King Ferdinand III of Sicily (a.k.a. Ferdinand IV of Naples, a.k.a Ferdinand I of the Two Sicilies). King Ferdinand was taking refuge in Palermo at the time, the Kingdom of Naples having been conquered by the French in 1798. The "Ferdinandea" part was not acceptable to other nations of the world and was dropped. Ceres was also called Hera for a short time in Germany. The regular adjectival form of the name would be Cererian, although the nonce forms Cerian and Cerea ...

Ceres is the largest known asteroid in the asteroid belt, which mostly lies between Mars and Jupiter. However the Kuiper belt is known to contain larger objects, including Pluto, 50000 Quaoar, 90482 Orcus, the recently discovered 2003 UB313, and possibly 90377 Sedna. At certain points in its orbit, Ceres can reach a magnitude of 7.0. This is generally regarded as being just barely too dim to be seen with the naked eye, but under exceptional viewing conditions a very sharp-sighted person may be able to see the asteroid with the naked eye. The only other aste ...
