Orbital inclination is
7.005° to Ecliptic
3.38° to Sun’s equator
6.34° to Invariable plane
Obliquity (axial tilt relative to it's orbit, which for earth is ~ 23 1/2 degrees, and causes our seasons) is 2.11 =/- 0.1 arc minutes, or 0.035 degree. ( Margot, J.L. et al, Science, Volume 316, Issue 5825, pp. 710- (2007).) close(-)
