No, there are about #63000# astronomical units in a light year.

An astronomical unit - the average distance between the Earth and the Sun - is approximately #500# light seconds.

There are #86400# seconds in a day and approximately #365.25# days in a year, Hence the number of astronomical units in one light year is approximately:

#(365.25 * 86400)/500 ~~ 63000#
