Light year means, Eg: When we travel at a speed of light(3*10^8m/s) we will cover the distance of sun in 8sec.

Yes it's correct, light travels in one year is called light year, we can measure the distance.

Light is the fastest one till today so we use light to measure the distance of heavenly bodies by knowing their speed in free space.

It is very big unit of distance that's why we can not use in daily life.

Distance travelled by a light in one year in vacuum.
Distance travelled = velocity of light * one year
1 light year = 9.467 *10^15 m.
Distance travelled = velocity of light * one year
1 light year = 9.467 *10^15 m.

Light year means a light is the distance travelled in one year is 1 light year and it is used to measure distance so, one light is equal to 9.4 *10^15.
