Time Interval
Light would have traveled
Example
One Second
299,792,458 metres,
Often rounded to 300,000 km/s
Earth to the moon is 400,000 km
= 1.3 Seconds
One Minute
17,987,547 km
or around 18 Million km
Earth to Sun 152 million km
= 8 minutes
One Hour
1,079,252,849 km
or around 1 Billion km
One Day
25,902,068,371 km
One Year
9,454,254,955,488 km
or around 9.5 Trillion km
Nearest Star to the Sun is 40 trillion km.
which is 4.3 light years away
"Light Year"
is distance light will travel in one Yeary
and use to measure very large distances involved astronomy
9.5 Trillion km
