what do you need ?
there are many sources for the earth - it depends on the resilution you need

for the moon the current is the LROC-NAC stereo gridded data

for mars the old MOLA data for the full planet
or
the stereo HIRIS and CTX data ( only a few places )

for other things like mars's two moons there are 3d meshes , even some of saterns moons have meshes
For Jupiter's moons there are a few that have some height data
