  The Sun and the Moon are quiescent gamma-ray sources that are clearly
detectable in Fermi-LAT data. While moving through the sky, the Sun and the
Moon can be a significant background in the analysis of Fermi-LAT data if they
pass through the region of interest. Accurate modeling of their intensity is
needed in this case, accounting for the correct exposure of their track along
the sky. We present the Solar System Tools (SST) which calculate the templates
of the Sun's and the Moon's intensity in the sky for a given observing period
and a model of their steady emission. These tools are available in the standard
Fermi-LAT Science Tools.
