Module:Celestial object quadrangle

Usage

For the quadrangle category, use

{{#invoke:Celestial object quadrangle|category|globe=GLOBE|lat=XX.XXX|lon=YY.YYY}}

or, for the quadrangle name, use

{{#invoke:Celestial object quadrangle|name|globe=GLOBE|lat=XX.XXX|lon=YY.YYY}}

Parameter	Description
globe	Name of the celestial object: moon, mars, mercury, or venus
lat	Degrees latitude (between -90 and 90)
lon	Degrees longitude (between -360 and 360)
