Attention!
"Did you know" is more polite than "Do you know" here.
This sentence means:
1. It's OK if you didn't know, because I can share the information with you. (Then the person who is asked the question will not feel uncomfortable if he/she did not know. )
2. You might already know, but it doesn't matter because I can still share the information with you and we can talk about it more.
We are talking about sth. that is always or generally true, i.e. facts, so we use the simple present here.
e.g. The teacher said there are 1,440
minutes in a day.
