What is Light year?
It is the distance light travels in one year
So how far is that? Light travels: 186,000 mi/sec 300,000 km/sec
What is Light year?In 1minute: 300,000 x 60 = 18,000,000 km
1.8 x 10 km
In 1 hour: 18,000,000 x 60 = 1,080,000,000 km
1.08 x 10 km
In 1 day: 1,080,000,000 x 24 = 25,920,000,000 km
2.592 x 10 km
In 1 year: 25,920,000,000 x 365 =
9,460,800,000,000 km
