Hermann Mayer Salomon Goldschmidt
Hermann Mayer Salomon Goldschmidt (June 17, 1802 – August 30 or September 10 1866) was a German-French astronomer and painter who spent much of his life in France. He started out as a painter, but after attending a lecture by the famous French astronomer Urbain Le Verrier turned to astronomy. His discovery of the asteroid Lutetia in 1852 was followed by further findings and by 1861 Goldschmidt had discovered 14 asteroids. He received the Gold Medal of the Royal Astronomical Society in 1861 for having discovered more asteroids than any other person up to that time. He died from complications of diabetes. Life and work Goldschmidt was born in Frankfurt as the son of a Jewish merchant. During a journey to the Netherlands, Goldschmidt visited Dutch picture galleries. The impression of this visit convinced him to become a painter. He studied art in Munich for several years under supervision of such famous painters as Peter von Cornelius and Julius Schnorr von Carolsfeld. To com ...

54 Alexandra
54 Alexandra is a carbonaceous asteroid from the intermediate asteroid belt, approximately 155 kilometers in diameter. It was discovered by German-French astronomer Hermann Goldschmidt on 10 September 1858, and named after the German explorer Alexander von Humboldt; it was the first asteroid to be named after a male. Description On May 17, 2005, this asteroid occulted a faint star (magnitude 8.5) and the event was observed and timed in a number of locations within the U.S. and Mexico. As a result, a silhouette profile was produced, yielding a roughly oval cross-section with dimensions of 160 × 135 km (± 1 km).D.W. Dunham, "Upcoming Asteroid Occultations", ''Sky & Telescope'', June, 2006, p. 63. The mass of the asteroid can be estimated based upon the mutually perturbing effects of other bodies, yielding an estimate of . Photometric observations of this asteroid during 1990–92 gave a light curve with a period of 18.14 ± 0.04 hours and a brightness variation o ...

52 Europa
52 Europa is the List of exceptional asteroids, sixth largest asteroid in the asteroid belt, having a diameter of over 300 km, though it is not correspondingly massive. It is not round but is shaped like an ellipsoid of approximately 380×330×250 km. It was discovered on 4 February 1858, by Hermann Goldschmidt from his balcony in Paris. It is named after Europa (mythology), Europa, one of Zeus's conquests in Greek mythology, a name it shares with Jupiter's moon Europa (moon), Europa. Physical characteristics file: 52 Europa Lightcurve Inversion.png, left, 3D model of ''Europa'' based on lightcurve modeling Europa is approximately the sixth largest asteroid by volume. Most likely it has a density of around 1.5 g/cm3, typical of C-type asteroids. In 2007, James Baer and Steven R. Chesley estimated Europa to have a mass of kg. A more recent estimate by Baer suggests it has a mass of 3.27 kg. Europa is a very dark carbonaceous C-type asteroid, C-type, and is the ...

49 Pales
49 Pales () is a large, dark main-belt asteroid. It was discovered by German-French astronomer Hermann Goldschmidt on 19 September 1857 from his balcony in Paris. The asteroid is named after Pales, the goddess of shepherds in Roman mythology. Since it was discovered on the same night as 48 Doris, geologist Élie de Beaumont suggested naming the two "The Twins". The orbit of this asteroid has close to a 2:1 commensurability with the orbit of Jupiter. On 17 January 2000, this minor planet was observed occulting a 9th magnitude star from seven locations. These timed chords across the silhouette allowed an estimate to be made of the object's dimensions, yielding a cross-section of . Pales has been studied by radar Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site.

48 Doris
48 Doris is one of the largest main belt asteroids. It was discovered on 19 September 1857 by Hermann Goldschmidt from his balcony in Paris. To find a name for the object, Jacques Babinet of the Academy of Sciences created a shortlist and asked the geologist Élie de Beaumont to make the selection. De Beaumont chose Doris, after an Oceanid in Greek mythology. Since Doris was discovered on the same night as 49 Pales, de Beaumont suggested naming the two "The Twins". Physical characteristics An occultation An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks f ... on 19 March 1981 suggested a diameter of 219±25 km. Observations of an occultation on 14 October 1999, using four well-placed chords, indicate an ellipsoid of 278×142 km and that 48 Doris is an extremely irreg ...

45 Eugenia
45 Eugenia is a large asteroid of the asteroid belt. It is famed as one of the first asteroids to be found to have a moon orbiting it. It was also the second triple asteroid to be discovered, after 87 Sylvia. Discovery Eugenia was discovered on 27 June 1857 by the Franco–German amateur astronomer Hermann Goldschmidt. His instrument of discovery was a 4-inch aperture telescope located in his sixth floor apartment in the 6th Arrondissement of Paris. It was the forty-fifth minor planet to be discovered. The preliminary orbital elements were computed by Wilhelm Forster in Berlin, based on three observations in July, 1857. The asteroid was named by its discoverer after Empress Eugenia di Montijo, the wife of Napoleon III. It was the first asteroid to be definitely named after a real person, rather than a figure from classical legend. Physical characteristics Eugenia is a large asteroid, with a diameter of 214 km. It is an F-type asteroid, which means that it is very da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
44 Nysa
44 Nysa is a large and very bright main-belt asteroid, and the brightest member of the Nysian asteroid family. It is classified as a rare class E asteroid and is probably the largest of this type (though 55 Pandora is only slightly smaller). Discovery It was discovered by Hermann Goldschmidt on May 27, 1857, and named after the mythical land of Nysa in Greek mythology. Physical properties In 2002 Kaasalainen ''et al.'' used 63 lightcurves from the Uppsala Asteroid Photometric Catalog (UAPC) to construct a shape model of 44 Nysa. The shape model is conical, which they interpreted as indicating the asteroid may actually be a contact binary. In 2003, Tanga ''et al.'' published results obtained from the Fine Guidance Sensor on the Hubble Space Telescope in which high-precision interferometry was performed on Nysa with the goal of a more accurate shape determination. Due to Hubble's orbit around the Earth, hours-long photometry sessions, as are normally used to resolve t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
41 Daphne
41 Daphne is a large asteroid from the asteroid belt. It is a dark-surfaced body 174 km in diameter is probably composed of primitive carbonaceous chondrites. The spectra of the asteroid displays evidence of aqueous alteration. It was discovered by H. Goldschmidt on May 22, 1856, and named after Daphne, the nymph in Greek mythology who was turned into a laurel tree. Incorrect orbital calculations initially resulted in 56 Melete being mistaken for a second sighting of Daphne. Daphne was not sighted again until August 31, 1862. The orbit of 41 Daphne places it in a 9:22 mean motion resonance with the planet Mars. The computed Lyapunov time for this asteroid is 14,000 years, indicating that it occupies a chaotic orbit that will change randomly over time because of gravitational perturbations of the planets. In 1999, Daphne occulted three stars, and on July 2, 1999, produced eleven chords indicating an ellipsoid of 213×160 km. Daphnean lightcurves also suggest that th ...

40 Harmonia
40 Harmonia is a large main-belt asteroid. It was discovered by German-French astronomer Hermann Goldschmidt on March 31, 1856, and named after Harmonia, the Greek goddess of harmony. The name was chosen to mark the end of the Crimean War. The asteroid is orbiting the Sun with a period of and a relatively low eccentricity of 0.046. It has a cross-sectional size of 107.6 km. The spectrum of 40 Harmonia matches an S-type (silicate) in the Tholen classification system, and is similar to primitive achondrite meteorites. Photometric observations at the Organ Mesa Observatory in Las Cruces, New Mexico during 2008–09 were used to generate a light curve that showed four unequal minima and maxima per cycle. The curve shows a period of 8.909 ± 0.001 hours with a brightness variation of 0.28 ± 0.02 in magnitude. This result is compatible with previous studies. Speckle interferometric observations carried out with the Nicholas U. Mayall Telescope at the Kitt Peak National O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
36 Atalante
36 Atalante is a large, dark main-belt asteroid. It was discovered by the German-French astronomer H. Goldschmidt on October 5, 1855, and named by French mathematician Urbain Le Verrier after the Greek mythological heroine Atalanta (of which ''Atalante'' is the French and German form, pronounced nearly the same as 'Atalanta' in English). It was rendered 'Atalanta' in English sources in the 19th century. This asteroid is classified as C-type (carbonaceous), according to the Tholen classification system. Observation of the asteroid light curve indicates it is rotating with a period of . During this interval, the magnitude varies by an amplitude of 0.12 ± 0.02. By combining the results of multiple light curves, the approximate ellipsoidal shape of the object can be estimated. It appears to be slightly elongated, being about 28.2% longer along one axis compared to the other two. Atalante was observed by Arecibo radar in October 2010. This asteroid shares a mean-motion resonanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
32 Pomona
32 Pomona ( ;) is a stony main-belt asteroid that is in diameter. It was discovered by German-French astronomer Hermann Mayer Salomon Goldschmidt on October 26, 1854, and is named after Pomona (mythology), Pōmōna, the Roman mythology, Roman goddess of fruit trees. Photometry (astronomy), Photometric observations of this asteroid gave a light curve with a synodic rotation period of 9.448 hours. The data was used to construct a model for the asteroid, revealing it to be an angular object that is spinning about a pole with ecliptic coordinates (β, λ) = (+58°, 267°). The ratio of the major to minor axes' lengths is roughly equal to 1.3. The spectrum of 32 Pomona matches an S-type asteroid, S-type in the Tholen classification system, and is similar to primitive achondrite meteorites. Measurements of the thermal inertia of 32 Pomona give a value of around 20–120 m−2 K−1 s−1/2, compared to 50 for lunar regolith and 400 for coarse sand in an atmosphere. Observations Aust ...
