The nearest star to the earth is Proxima Centuri. It is   from New York City. The distance to Perth on the exact other side of the globe is about . Given that , how many  further from New York is Proxima Centuri compared to Perth?
Note: An order of magnitude is an estimate of size based on how many multiples of ten something is bigger or smaller compared to something else. If I have $1 and you have $200 we can say you have 2 orders of magnitude more money than me because it is two factors of 10 larger. If you had $1,000,000 it would be 6 orders of magnitude more. For this question we don't want you to say exactly how much farther this star is, but approximate in terms of orders of magnitude.
