Read Mercury's obliquity in the arcminutes its Horizons page gives it in

Mercury's page states "Obliquity to orbit[1] = 2.11' +/- 0.1'", in arcminutes, where every other
page writes degrees. The pattern took the number alone, so bodies.json had Mercury tilted 2.11
degrees, sixty times too far, and the system view drew it that way. It now reads the arcminute
mark and divides by 60: 0.0352 degrees, against the 0.034 the IAU's pole for Mercury makes with
its orbit.
