452 Hamiltonia
Hamiltonia (minor planet designation: 452 Hamiltonia) is an asteroid. It was discovered by James Edward Keeler on 6 December 1899, but was then lost until 1981. Its provisional name was 1899 FD. The asteroid is named for Mount Hamilton (California), Mount Hamilton, the site of Lick Observatory where Keeler was working when he discovered the asteroid. It was the last asteroid discovery of the 1800s. Leif Kahl Kristensen, L. K. Kristensen at Aarhus University rediscovered 452 Hamiltonia along with 1537 Transylvania along with numerous other small objects in 1981.(1537) Transylvania and (452) Hamiltonia Kristensen, L.

James Edward Keeler
James Edward Keeler (September 10, 1857 – August 12, 1900) was an American astronomer. He was an early observer of galaxies using photography, as well as the first to show observationally that the rings of Saturn do not rotate as a solid body. Career and personal life Keeler was born in La Salle Illinois, but grew up and spent the majority of his early life in Mayport, Florida near Jacksonville. His mother's father was a former Governor of Connecticut, Henry Dutton. Keeler worked at Lick Observatory beginning in 1888, but left after being appointed director of the University of Pittsburgh's Allegheny Observatory in 1891. He returned to Lick Observatory as its director in 1898, but died not long after in 1900. Keeler suffered from a heart weakness that went undiagnosed until shortly before his death. On the 12th of August he died from a sudden stroke. His ashes were interred in a crypt at the base of the 31-inch Keeler Memorial telescope at the Allegheny Observatory. ...

330 Adalberta
330 Adalberta ( ''prov. designation'': ) is a stony asteroid from the inner regions of the asteroid belt, approximately 9.5 kilometers in diameter. It is likely named for either Adalbert Merx or Adalbert Krüger. It was discovered by Max Wolf in 1910. In the 1980s, the asteroid's permanent designation was reassigned from the non-existent object . Discovery ''Adalberta'' was discovered on 2 February 1910, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany. Previously, on 18 March 1892, another body discovered by Max Wolf with the provisional designation was originally designated , but was subsequently lost and never recovered ''(also see Lost minor planet)''. In 1982, it was determined that Wolf erroneously measured two images of stars, not asteroids. As it was a false positive and the body never existed, the name ''Adalberta'' and number "330" was then reused for this asteroid, . MPC citation was published on 6 June 1982 ().

Lost Asteroids
A minor planet is "lost" when today's observers cannot find it, because its location is too uncertain to target observations. This happens if the orbital elements of a minor planet are not known accurately enough, typically because the observation arc for the object is too short, or too few observations were made before the object became unobservable (e.g. too faint due to increasing distance, or too close to the Sun to view at night). By some definitions thousands, if not tens of thousands, of mostly small observed minor planets are lost. Some lost minor planets discovered in decades past cannot be found because the available observational data is insufficient for reliable orbit determination. With limited information astronomers cannot know where to look for the object at future dates. Lost objects are sometimes recovered when serendipitously re-observed by a later astronomical survey. If the orbital elements of the newly found object are sufficiently close to those of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1179 Mally
1179 Mally, provisional designation , is an asteroid and long-lost minor planet from the central region of the asteroid belt, approximately 13 kilometers in diameter. Discovered by Max Wolf in 1931, the asteroid was lost until its rediscovery in 1986. The discoverer named it after his daughter-in-law, Mally Wolf. Discovery and rediscovery ''Mally'' was discovered on 19 March 1931, by German astronomer Max Wolf at Heidelberg Observatory in southwest Germany. Soon after its initial discovery, it became one of few well known lost minor planets for over 55 years. In 1986, ''Mally'' was rediscovered by astronomers Lutz Schmadel, Richard Martin West and Hans-Emil Schuster, who remeasured the original discovery plates and computed alternative search ephemerides. This allowed them to find the body very near to its predicted position. In addition, historic photographic plates from the Palomar Sky Survey (1956–1958), the UK Schmidt Telescope (Australia), and the ESO Schmidt Telesco ...

1026 Ingrid
1026 Ingrid, provisional designation , is a stony Florian asteroid and long-lost minor planet (1923–1986) from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered by Karl Reinmuth at Heidelberg in 1923, and later named after Ingrid, niece and godchild of astronomer Albrecht Kahrstedt. Discovery and recovery ''Ingrid'' was discovered on 13 August 1923, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was observed for only a few days during August 1923, before it became a lost minor planet for nearly 63 years until its recovery by Japanese astronomer Syuichi Nakano in 1986. Nakano was able to show that ''Ingrid'' had been observed and provisionally designated several times during its lost period: as at the discovering Heidelberg Observatory in October 1957, possibly as at Goethe Link Observatory in April 1963, as at the Crimean Astrophysical Observatory in No ...

1009 Sirene
Sirene (minor planet designation: 1009 Sirene), provisional designation , is an eccentric asteroid and sizable Mars-crosser from the central regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory on 31 October 1923. The asteroid was named after the Siren from Greek mythology. Orbit and classification ''Sirene'' is a Mars-crossing asteroid with a notably large semi-major axis is 2.62 AU, due to its high eccentricity of 0.46. It orbits the Sun in the central main-belt at a distance of 1.4–3.8 AU once every 4 years and 3 months (1,552 days). Its orbit has an inclination of 16 ° with respect to the ecliptic. The body's observation arc begins 9 days after its official discovery observation at Bergedorf Observatory in Hamburg. On 8 June 1949, ''Sirene'' passed from Mars. Aethra group and mass of Mars ''Sirene'' had been of great interest in 1930s. Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
878 Mildred
878 Mildred is a minor planet in the main belt orbiting the Sun. It is the lowest numbered, and thus the namesake, of the Mildred family of asteroids, a subgroup of the Nysa family. The Mildred subgroup, and by extension 878 Mildred itself, is thought to have been formed by a recent fragmentation event from a larger asteroid. Discovery 878 Mildred was originally discovered in 1916 using the 1.5 m Hale Telescope at the Mount Wilson Observatory, but was subsequently lost until it was again observed on single nights in 1985 and 1991 (a lost asteroid). Initially only two observations of the asteroid were taken on 1916-09-06 which does not allow for an accurate orbital determination, however interest in the object prompted further investigation and more measurements were taken in late September and October. The asteroid was re-discovered in 1991 by Gareth V. Williams. It is named after Mildred Shapley Matthews. Physical properties By comparing the asteroid's perceived brightness ...
