Light travels in a vacuum at 299,792,458 metres per second

As there are 365.25 days in a year, each of 24 hours, each of 60 minutes, each of 60 seconds, there are 60 x 60 x 24 x 365.25 seconds in a year .... 31,557,600 .... this gets us into two HUGE numbers.

A light year is officially defined as 9,460,730,472,580.8 kilometres or 9.461×1012 km
