Whatever the case in this respect, it appears that any metallic core region, if present, has not been exposed. 15 Eunomia is a very big asteroid in the closer part of the main asteroid belt. It is the largest of the stony (S-type) asteroids, and somewhere between the 8th- and 12th-largest main-belt asteroid overall (uncertainty in diameters causes uncertainty in its ranking). It is a retrograde rotator with its pole pointing towards ecliptic coordinates (β, λ) = (-65°, 2°) with a 10° uncertainty. An older explanation of the compositional differences, that Eunomia is a mantle fragment of a far larger parent body (with a bit of crust on one end, and a bit of core on the other), appears to be ruled out by studies of the mass distribution of the entire Eunomia family. It is the largest of the stony (S-type) asteroids, and somewhere between the 8th-to-12th-largest main-belt asteroid overall (uncertainty in diameters causes uncertainty in its ranking).
[2 Asteroid 15 Eunomia will be well placed, lying in the constellation Sagittarius, well above the horizon for much of the night..

David Erwin, the lone human inhabitant at the Eunomia mining station in the asteroid belt, was just suiting up to make his rounds when his door chime sounded. Asteroid 15 Eunomia is currently in the constellation of Gemini.The current Right Ascension of Asteroid 15 Eunomia is 07h 55m 13s and the Declination is +24° 53’ 29” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom []).The current magnitude of Asteroid 15 Eunomia is 10.01 (JPL).

Actual rotational axis may differ from planetocentric poles, especially for small irregular bodies. This composition indicates that the parent body was likely subject to magmatic processes, and became at least partially differentiated under the influence of internal heating in the early period of the Solar System. Astronomy & Astrophysics 607, A117, 2017. Eunomia é o asteroide nº 15 da série.
Regardless of your location on the Earth, 15 Eunomia will reach its highest point in the sky around midnight local time. These indications are also in accord with recent mass determinations which indicate that Eunomia's density is typical of mostly intact stony asteroids, and not the anomalously low "rubble pile" density of ~1 g/cm3 that had been reported earlier. It is the largest Eunomian asteroid, and is estimated to contain 1% of the mass of the asteroid belt.
Regardless of your location on the Earth, 15 Eunomia will reach its highest point in the sky around midnight local time. Eunomia (Model 1) Eunomia (Viikinkoski) Please note that the models are in planetocentric coordinate system, with Z axis passing through north pole. As the biggest S-type asteroid (with 3 Juno being a very close second), Eunomia has attracted a moderate amount of scientific attention.
Eunomia appears to be an elongated but fairly regularly shaped body, with what appear to be four sides of differing curvature and noticeably different average compositions. The celestial coordinates, magnitude, distances and speed are updated in real time and are computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements for details).

Like other true members of the family, its surface is composed of silicates and some nickel-iron, and is quite bright. 15 Eunomia. Spectroscopic studies suggest that Eunomia has regions with differing compositions: A larger region dominated by olivine, which is pyroxene-poor and metal-rich, and another somewhat smaller region on one hemisphere (the less pointed end) that is noticeably richer in pyroxene, and has a generally basaltic composition.
