. Définitions de (704) Interamnia, synonymes, antonymes, dérivés de (704) Interamnia, dictionnaire analogique de (704) Interamnia (français) Our observations reveal a shape that can be well approximated by an ellipsoid, and that is compatible with a fluid hydrostatic equilibrium at the 2 σ level.

En 2007, Baer et Chesley ont estimé la masse d'Interamnia à (7,12 ± 0,84) ×1019.

Even at a near-perihelion opposition its magnitude is only around +9.9, which is over four magnitudes lower than Vesta.

Sa distance moyenne du Soleil est 3,067 ( UA). Il s'agit probablement du cinquième astéroïde le plus massif après Cérès, Vesta, Pallas et Hygie, avec une masse estimée à 1,2% de la masse totale de la ceinture principale d'astéroïdes.

With an estimated diameter in the 320-350 km range, (704) Interamnia is the fifth largest main belt asteroid and one of the few bodies that fills the gap in size between the four largest bodies with D > 400 km (Ceres, Vesta, Pallas and Hygiea) and the numerous smaller bodies with diameter ≤200 km. Models.

Its orbit is a bit more eccentric that of Hygiea (15% versus 12%) but is different because Hygiea's orbit is much more inclined and takes a bit shorter to complete one orbit. Abstract: For the first time, spectral signs of subtle coma activity were observed for four main-belt primitive asteroids (145) Adeona, (704) Interamnia, (779) Nina, and (1474) Beira around their perihelion distances in September 2012, which were interpreted as manifestations of the sublimation of H2O ice in/under the surface matter (Busarev et al., 2015a, 2015b).

We aimed to test at what size and mass the shape of a small body departs from a nearly ellipsoidal equilibrium shape (as observed in the case of the four largest asteroids) to an irregular shape as routinely observed in the case of smaller (D ≲ 200 km) bodies. Its very dark surface and fairly far distance from the Sun means Interamnia can never be seen with 10x50 binoculars.

Interamnia's volume-equivalent diameter of 332 ± 6 km implies a bulk density of ρ=1.98 ± 0.68 gcm−3 , which suggests that Interamnia - like Ceres and Hygiea - contains a high fraction of water ice, consistent with the paucity of apparent craters. For the first time, spectral signs of subtle coma activity were observed for four main-belt primitive asteroids (145) Adeona, (704) Interamnia, (779) Nina, and (1474) Beira around their perihelion distances in September 2012, which were interpreted as manifestations of the sublimation of H 2 O ice in/under the surface matter (Busarev et al., 2015a, 2015b). It is probably the fifth-to-eighth-most-massive asteroid, with a mass estimated to be 1.2% of the mass of the entire asteroid belt.

En 2001, Michalak a estimé la masse d'Interamnia à 6,9×1019 kg. (704) Interamnia est un gros astéroïde de la ceinture principale, dont le diamètre est estimé à 350 kilomètres.

Any large craters must have flat floors, consistent with an icy C/F-type composition.

At most oppositions its magnitude is around +11.0, which is less than the minimum brightness of Vesta, Ceres or Pallas. [10] Observations of a favorable occultation of a bright 6.6 magnitude star on March 23, 2003, produced thirty-five chords indicating an ellipsoid of 350×304 km,[11][12] thus giving the asteroid a geometric mean diameter of 326 km.

It is unlikely to collide with Pallas because their nodes are located too far apart, whilst although its nodes are located on the opposite side from those of Ceres, it is generally clear of Ceres when both cross the same orbital plane and a collision is again unlikely.

Il a été découvert le 2 octobre 1910 par l'astronome italien Vincenzo Cerulli, et nommé d'après le nom latin de la ville de Teramo en Italie, où Cerulli est né, a travaillé et fait construire son observatoire privé. Les mesures d'IRAS en 1983 ont estimé un diamètre de l'astéroïde à environ 317 ± 5 km. Il est peu probable qu'Interamnia puisse entrer en collision avec (2) Pallas parce que leurs nœuds ascendant sont trop distants. This page was last changed on 26 April 2019, at 11:20.

Les observations lors d'occultations favorables par un astre brillant de magnitude 6.6 le 23 mars 2003, ont produit trente-cinq cordes indiquant une ellipsoïde de 350 × 304 km, et donnant ainsi à l'astéroïde une moyenne géométrique pour son diamètre de 326 km. En 2010, Baer a suggéré qu'Interamnia possédait une masse de seulement (3,90 ± 0,18) ×1019 kg. We observed Interamnia as part of our ESO VLT/SPHERE large program (ID: 199.C-0074) at thirteen different epochs.
