nearhemispherical

nearhemispherical refers to an object or shape that closely approximates a hemisphere but is not a perfect half-sphere. This means it is approximately half of a sphere, but may have slight deviations from a true hemispherical form. The term suggests a shape that is almost, but not entirely, hemispherical. For example, a bowl that is very deep and round might be described as nearhemispherical if its internal shape is nearly half of a sphere, but perhaps slightly flattened at the base or with a rim that is not a perfect circle. Similarly, certain geological formations or astronomical bodies could exhibit nearhemispherical characteristics. The degree to which a shape is considered nearhemispherical is subjective and depends on the context and the acceptable tolerance for deviation from a perfect hemisphere. It implies a substantial portion of a spherical shape, specifically around half of it, without the strict geometrical definition.
