possible voorwerp, the nearby galaxy is a quasar too.

No voorwerp here. Looks like a galaxy overlap.

Ok, but I’m curious about why is not a voorwerp.

Because it shows no characteristics that are consistent with a voorwerp. What made you believe it was a voorwerp?

It looks like a voorwerp to me but I’m just a newbie, so I don’t know how to rule out voorwerp false positives, so can you tell me what characteristics does voorwerps have?

Vibrant colours are a telltale sign. Look for bright blue/purple and green. The fact that the object is yellow (the same color as the main galaxy) indicates that it is a background galaxy.
