The sphere command creates a three-dimensional plot data object, which when displayed is a sphere centered at c and of radius r.  The default values for c and r are $\left[0\,0\,0\right]$ and $1$, respectively.

A call to sphere produces a plot data object, which can be used in a PLOT3D data structure, or displayed using the plots:-display command.

Remaining arguments are interpreted as options, which are specified as equations of the form option = value. For more information, see plottools and plot3d/option.
