A number can be written as
in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
So, the distance in scientific notation is : ![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
