10 Hygiea is a major asteroid located in the main asteroid belt.With a mean diameter of between 425 and 440 km and a mass estimated to be 3% of the total mass of the belt, [11] it is the fourth-largest asteroid in the Solar System by both volume and mass, and is the largest of the C-type asteroids (dark asteroids with a carbonaceous surface) in classifications that use G type for 1 Ceres.
Location and structure of the Hygiea family. By far the largest member is 10 Hygiea, a 400 km diameter C-type asteroid that is the fourth largest in the belt. The remaining members are much smaller so Hygiea contains about 94–98% of the mass in the family (depending on the exact criteria for inclusion).
Mass switches from 10 21 kg to 10 18 kg (Zg). Main-belt asteroids have orbital elements constrained by (2.0 AU < a < 3.2 AU; q > 1.666 AU) according to JPL Solar System Dynamics (JPLSSD). [98] Many TNOs are omitted from this list as their sizes are poorly known. [58]

The list of minor planets consists of more than 700 partial lists, each containing 1000 minor planets grouped into 10 tables. The data is sourced from the Minor Planet Center (MPC) and expanded with data from the JPL SBDB (mean-diameter), Johnston's archive (sub-classification) and others (see detailed field descriptions below).
This asteroid was the 3rd to be discovered and is 9th in mass ranking (1 Ceres, 2 Pallas, 4 Vesta, 10 Hygiea, 511 Davida, 704 Interamnia, 65 Cybele, 52 Europa are considerably bigger and more massive). In mythology Juno is the Roman equivalent of the Greek Hera. Hera was a very important goddess in both Greek and Roman culture.
Bobkepple is a member of the Hygiea family (), [3] a large family of carbonaceous outer-belt asteroids, named after 10 Hygiea, the main belt's fourth-largest asteroid. [6] It orbits the Sun in the outer main-belt at a distance of 2.7–3.7 AU once every 5 years and 9 months (2,091 days).
The list below concerns those minor planets in the specified number-range that have received names, and explains the meanings of those names. Official naming citations of newly named small Solar System bodies are approved and published in a bulletin by IAU's Working Group for Small Bodies Nomenclature (WGSBN). [ 1 ]
