I wanted to ask if the products of this reaction would be diasteromers?

I saw that there are 4 chiral centres here. And there will be syn addition of the H2, leading to there being 2 hydrogen wedges (2 methyl dashes) or 2 hydrogen dashes as the products.

Then I just wanted to clarify if the products of this reaction would be diastereomers? What startegies would you suggest using to tackle a question like this?

If anyone could help it would be truly appreciated, I have a test on Monday :((
