The word "oblique sphere" is spelled using the IPA phonetic transcription as /əˈbliːk/ /sfɪər/. It refers to a sphere that is not positioned directly perpendicular to a given plane or surface. The first part of the word, "oblique", is pronounced with a schwa sound, and the second part "sphere" is pronounced with a long "e" sound followed by an "r". This word is commonly used in geometry and mathematics to describe three-dimensional shapes that do not have perfect symmetry.
An oblique sphere refers to a theoretical concept in geometry that describes a three-dimensional spherical shape that is not symmetrically positioned with respect to a plane or axis. It is formed when a sphere is inclined at an angle, other than 0 or 90 degrees, with respect to a reference plane or axis. This inclination causes the oblique sphere to appear distorted, with elongated or compressed dimensions, when compared to a perfectly symmetric sphere.
In an oblique sphere, the curvature along one meridian is different from the curvature along the orthogonal meridian. This non-uniform curvature results in apparent distortion and asymmetry of the surface of the sphere, leading to its oblique nature. Moreover, the projection of an oblique sphere onto a flat plane produces a distorted image, unlike the accurate representation obtained when projecting a symmetrical or aligned sphere.
Oblique spheres find applications in various fields, such as astronomy, cartography, and 3D computer graphics. Astronomers use oblique spheres to model celestial bodies that have axial tilts, like Uranus. In cartography, oblique spheres are utilized to create accurate maps of the Earth's surface, considering the planet's oblateness and rotational axis. Additionally, 3D computer graphics artists employ oblique spheres to depict realistic objects or simulate spatial environments with non-standard perspectives or orientations. The study of oblique spheres allows researchers and professionals to accurately describe and manipulate geometric shapes in scenarios where symmetry is not present.
The sphere in that position in which the circles apparently described by the heavenly bodies in their diurnal rotation are oblique to the horizon.

The word "oblique" derives from the Latin word "obliquus", which means "slanting" or "sideways". It is formed by combining the prefix "ob" (meaning "against" or "toward") and "liquis" (meaning "smooth" or "slippery").
The word "sphere" comes from the Greek word "sphaira", which also means "sphere" or "ball". It has roots in other ancient languages such as Sanskrit and Old English.
When combined, the term "oblique sphere" essentially refers to a sphere that is slanted or tilted, deviating from the regular form. It is commonly used in geometry or astronomy to describe a sphere that is not aligned with the reference points or planes.
