There is no term for 10^13 in the System International System of Units
(SI).  All the prefixes represent powers of ten where the exponent is
divisible by 3 except centi- and hecto-  which represent 10^-2 and
10^2 respectfully.  

To represent 10^13 meters, use 10 terameters.  To represent 10^14
meters use 100 terameters.  When you get to 10^15 then you may use
1 petameter.

Take a look at this website for a better explanation of SI Units:
