**1. The problem statement, all variables and given/known data**

What are the magnitud of G (gravitational constant) and the age of the solar system in CGS system of units and in seconds respectively? and what is the precision of these values and why?

**2. Relevant equations**

**3. The attempt at a solution**

I found that the value of G in CGS system is 6.674 X 10^{-8} cm^{3}g^{-1}s^{-2}(approximately) and the age of the solar system is 4600 million years and in secons is : 1.450656 X 10^{17} seconds (approximately)

So my question is: what is the precision of these values? and why? do I need to put the uncertainities? I also found that the gravitational constant has a precision of 1 over 10,000 but why? so I really would appreciate your help đź™‚
