How do you multiply by something with two significant figure precision to get something quoted to 7 significant figures?

Good point. I need a better figure for KM per AU

<p>As we all know the usual distance between earth and moon is 384,400 km.
But i was thinking how much closer it will be on 14 November 2016, as it will be a supermoon, the brightest and biggest moon in 60 years.</p>

This is really far too simple a question to be worth keeping in this site.
