Petit-Prince (moon)
(45) Eugenia I Petit-Prince is the larger, outer moon of asteroid 45 Eugenia. It was discovered in 1998 by astronomers at the Canada-France-Hawaii Telescope on Mauna Kea, Hawaii. Initially, it received the provisional designation S/1998 (45) 1. Petit-Prince was the first asteroid moon to be discovered with a ground-based telescope. Previously, the only known moon of an asteroid was Dactyl, discovered by the Galileo space probe, around 243 Ida. Characteristics Petit-Prince is 13 km in diameter, compared to 45 Eugenia's 214 km. It takes five days to complete an orbit around Eugenia. Name The discoverers chose the name in honour of Empress Eugénie's son, the Prince Imperial. However, they also intended an allusion to the children's book ''The Little Prince'' by Antoine de Saint-Exupéry, which is about a prince who lives on an asteroid. In their submission of the name to the IAU The International Astronomical Union (IAU; french: link=yes, Union astronomique ...

Infobox Planet
An infobox is a digital or physical table used to collect and present a subset of information about its subject, such as a document. It is a structured document containing a set of attribute–value pairs, and in Wikipedia represents a summary of information about the subject of an article. In this way, they are comparable to data tables in some aspects. When presented within the larger document it summarizes, an infobox is often presented in a sidebar format. An infobox may be implemented in another document by transcluding it into that document and specifying some or all of the attribute–value pairs associated with that infobox, known as parameterization. Wikipedia An infobox may be used to summarize the information of an article on Wikipedia. They are used on similar articles to ensure consistency of presentation by using a common format. Originally, infoboxes (and templates in general) were used for page layout purposes. An infobox may be transcluded into an article by ...

243 Ida
Ida, minor planet designation 243 Ida, is an asteroid in the Koronis family of the asteroid belt. It was discovered on 29 September 1884 by Austrian astronomer Johann Palisa at Vienna Observatory and named after a nymph from Greek mythology. Later telescopic observations categorized Ida as an S-type asteroid, the most numerous type in the inner asteroid belt. On 28 August 1993, Ida was visited by the uncrewed ''Galileo'' spacecraft while en route to Jupiter. It was the second asteroid visited by a spacecraft and the first found to have a natural satellite. Ida's orbit lies between the planets Mars and Jupiter, like all main-belt asteroids. Its orbital period is 4.84 years, and its rotation period is 4.63 hours. Ida has an average diameter of . It is irregularly shaped and elongated, apparently composed of two large objects connected together. Its surface is one of the most heavily cratered in the Solar System, featuring a wide variety of crater sizes and ages. Ida's moon Dact ...

Asteroid Satellites
An asteroid is a minor planet of the Solar System#Inner solar system, inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type asteroid, C-type, M-type asteroid, M-type, and S-type asteroid, S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres (dwarf planet), Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slig ...

2578 Saint-Exupéry
2578 Saint-Exupéry, provisional designation , is an Eoan asteroid from the outer region of the asteroid belt, approximately 17 kilometers in diameter. It was discovered by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on 2 November 1975, and named after French aviator and writer Antoine de Saint-Exupéry. Classification and orbit ''Saint-Exupéry'' is a member the Eos family (), the largest asteroid family of the outer main belt consisting of nearly 10,000 known members.

Chislehurst
Chislehurst () is a suburban district of south-east London, England, in the London Borough of Bromley. It lies east of Bromley, south-west of Sidcup and north-west of Orpington, south-east of Charing Cross. Before the creation of Greater London in 1965, it was in Kent. History The name "Chislehurst" is derived from the Old English language, Saxon words ''cisel'', "gravel", and ''hyrst'', "wooded hill". The Walsingham family, including Christopher Marlowe's patron, Thomas Walsingham (literary patron), Sir Thomas Walsingham and Elizabeth I of England, Queen Elizabeth I's spymaster, Francis Walsingham, had a home in Scadbury Park, now a nature reserve in which the ruins of the house can still be seen. A water tower used to straddle the road from Chislehurst to Bromley until it was demolished in 1963 as one of the last acts of the Chislehurst and Sidcup UDC. It marked the entrance to the Wythes Estate in Bickley, but its narrow archway meant that double-decker buses were not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eugénie De Montijo
''Doña'' María Eugenia Ignacia Agustina de Palafox y Kirkpatrick, 19th Countess of Teba, 16th Marchioness of Ardales (5 May 1826 – 11 July 1920), known as Eugénie de Montijo (), was Empress of the French from her marriage to Emperor Napoleon III on 30 January 1853 until the Emperor was overthrown on 4 September 1870.

Galileo Probe
''Galileo'' was an American robotic space probe that studied the planet Jupiter and its moons, as well as the asteroids Gaspra and Ida. Named after the Italian astronomer Galileo Galilei, it consisted of an orbiter and an entry probe. It was delivered into Earth orbit on October 18, 1989, by , during STS-34. ''Galileo'' arrived at Jupiter on December 7, 1995, after gravitational assist flybys of Venus and Earth, and became the first spacecraft to orbit an outer planet. The Jet Propulsion Laboratory built the ''Galileo'' spacecraft and managed the ''Galileo'' program for NASA. West Germany Messerschmitt-Bölkow-Blohm supplied the propulsion module. NASA's Ames Research Center managed the atmospheric probe, which was built by Hughes Aircraft Company. At launch, the orbiter and probe together had a mass of and stood tall. Spacecraft are normally stabilized either by spinning around a fixed axis or by maintaining a fixed orientation with reference to the Sun and a star. ''Ga ...
