1 degree and 54 minutes, it turns out. Amazing when you think about that, isn't it?

I was thinking earth was about twice the diameter of the moon, hence 1 degree. Turns out it's closer to a factor of 4. Should have looked it up.

    I used units(1):

        : yeso; units
    Currency exchange rates from FloatRates (USD base) on 2025-10-06 
    3749 units, 113 prefixes, 120 nonlinear units

    You have: 2 arcsin(earthradius/moondist)
    Unknown unit 'arcsin'
    You have: 2 asin(earthradius/moondist)
    You want: dms
            1 deg + 53 arcmin + 57.540656 arcsec
