How would you write “through our love to the stars”?

Question

Similar to through hardship to the stars or “per aspera ad astra” as many of you already know, how would you write this? New to this site, thanks!

Answer 1

That would be:

per amorem nostrum ad astra

The preposition per takes the accusative, so it's just a matter of putting amor in the accusative singular and noster in the masculine accusative singular (since it has to agree with amor, a masculine word.)
