Hanami Planum is a highland area centered near 15°N, 130°W, primarily placing it inside the Occator quadrangle. Spanning about and rising as high as , it is the only discrete topographic high on Ceres It is the third largest geological feature on Ceres, after
Vendimia Planitia and
Samhain Catenae; the latter broadly coincides with Hanami Planum. Several major named
craters occupy the highland, including Nepen, Azacca, Lociyo, and the bright
Occator. Other major craters border Hanami Planum, such as Kirnis to the east and
Ezinu to the northwest. Hanami Planum is associated with a broad, distinct negative isostatic
gravity anomaly, meaning that local gravity is weaker than normal. The negative gravity anomalies suggest that Hanami Planum lies in a region of low-density material, with a mass deficit of , ~0.1% the mass of Ceres. The region includes the most extreme negative anomaly observed on Ceres, with a strength of < –95
mGal southeast of Occator at 12°N, 113°W. This anomaly is associated with a dome that rises above the surrounding terrain. Another distinct local anomaly crosses Samhain Catenae. It overlaps with a large dome within Kirnis and a high dome to the southwest. == See also ==
