Why do you think the axial tilt should (or should not) affect the orbital angular momentum?

Since there is an axial tilt present on planets, does this also affect their orbital angular momentum?

Well according to this [website](https://link.springer.com/10.1007%2F1-4020-4520-4_10):

> There are two contributions to the Earth's angular momentum: the spin angular momentum of rotation about an axis through its center of mass, and its orbital angular momentum about the Sun or mass center of the solar system.

The axial tilt probably doesn't affect the angular momentum. Since the equation for specific relative angular momentum is:

[![enter image description here](https://i.sstatic.net/9XLBg.png)](https://i.sstatic.net/9XLBg.png)

where $v$ is the velocity vector, $h$ is the specific relative angular momentum and [![r](https://i.sstatic.net/vSi5k.png)](https://i.sstatic.net/vSi5k.png) is the is the position vector from $m\_1$ to $m\_2$ with scalar magnitude $r$.
