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.

The Nov 14 2016 supermooon's expected peak of full phase
is on the morning ov Nov 14 at 8:52 AM EST

According to some quick calculations that I performed
using PyEphem

and assuming the moon would be viewed by an observer in NYC at 08:52AM EST

**0.00236372323707 AU** from observer
An AU is 1.5 \* 10^km

**Edit: I needed a better precision for km to AU**

<http://www.iau.org/static/resolutions/IAU2012_English.pdf>

According to this, the AU can be more precisely defined as
149 597 870 700 meters +/- 3 meters

0.00236372323707 \* 149 597 870 700 =

**353 607 963.19 meters** or

**~ 353,608 km from earth**

here is a quick run through of the inputs I used for the program

```
>>> moon = ephem.Moon()
>>> nyc = ephem.Observer()
>>> nyc.long, nyc.lat = '-74.0059', '40.7127'
>>> nyc.date = '2016/11/14 08:52:00'
>>> moon.compute(nyc)
>>> print moon.earth_distance

    0.00236372323707

```
