  texture {uv_mapping pigment {checker} scale <0.1, 0.147> }

With uv_mapping, the part of the texture that would normally cover the
square from <0,0> to <1,1> is mapped to the whole surface, even if the
sphere is much larger than that. But for the checker pattern, each of
the coloured checkers is a 1x1 square, so to see any pattern you need to
scale down.

[Because the pattern is in uv-space instead of xyz-space, only the first
two dimensions of scaling are meaningful.]
