Two dimensional geometry is called "plane geometry" meaning that it occurs on a single surface or plane. The objects used in plane geometry are called plane figures.
solid geometry deals with 3 dimensional figures while plane geometry deals with 2 dimensional.
Stars that populate the universe are not plane figures. They are oblate spheres.If, by a star, you mean a many-pointed flat figure then yes, it is.

No because in Geometry, a plane goes on infinitely. No because in Geometry, a plane goes on infinitely.
There are many special figures in geometry and some of them are pyramid, cone, cylinder, sphere, circle, prism, polygon, polyhedron ..... etc
An example is the Cartesian plane where coordinated geometry is plotted
There are infinitely many of them, and of a fantastically huge variety.
Noncoplanar is a term in geometry referring two or more figures, lines, or points that do not all lie in the same plane.
a plane; a study of geometry is called "plane" geometry.
Plane Geometry and Solid Geometry
Geometry that is not on a plane, like spherical geometry
