Just idle curiosity. But it must be pretty small.

I make it about 10^-35 radians. tell you what you conert that to degrees using pi rad =180deg and we'll all sleep more safely!

In round figures, 1 light year = 10^18 centimetres, so 1 billion of them = 10^27 centimetres, and 1 atom = 10^-8 centimetres so the angle is 10^-35 of a radian just as the previous answerer says. Pretty small, but still just a number. Much smaller numbers arise in some calculations in quantum physics.

No kidding!
Here's the formula you need:
δ = 2 arctan ((1/2d)/D),
in which δ is the angular diameter, and d and D are the diameter of and the distance to the object, expressed in the same units. When D is much larger than d, δ may be approximated by the formula δ = d / D, in which the result is in radians.
Let me know, it's gotta be infitessimal. The scientific notation on this one is going to have a lot of zeros!

You have reached the physical limit of the universe (as we currently understand it).
1.6Ã10â35 m is the Planck length (size of a "string", as in string theory)

Infinitesimal... that's about the best answer you can give. Very large and very small numbers are practically meaningless when it comes to comprehending their scale.

Sorry but i have to know what direction you are facing before I could possibly answer that question.
