To us, a bit of heaven (5)

I believe the answer is:
venus
'a bit of heaven' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'to us' is the wordplay.
'to' becomes 'ven' (I can't explain this - if you can you should give a lot more credence to this answer).
'ven'+'us'='VENUS'
Can you help me to learn more?
(Other definitions for venus that I've seen before include "Solar system planet" , "The embodiment of Love" , "One of the planets" , "Planet; goddess" , "Next planet in" .)
