On the 1 to 10 billion scale, about how far is it to the nearest stars besides the Sun?

Answer 1

On the scale 1 to 10 Billion km, the distance of the nearest star Proxima Centauri in the constellation Centaurus is 13100 units of 10 B km = 8141 units of 10 B miles..

Proxima Centauri is at a distance of 1.31017866 E+14 km / 1. E+10 = 13100, in the new unit = 1. E+10 km = 8141 units of 10 B miles. The distance of Proxima Centauri is thus equal to 4.246 ligh years = 4.246 X 206264,8 AU = 875800.3408 AU = 875800.34o8 X 149597870.7 km = 1.31017866 E+14 km.

Since there are only 4 standard deviations for the known distance of 4.246 ly, the answer was rounded to 4 sd. This convention is essential for reliability.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
