What is the solar system? Convert one light year into kilometers.
The family of sun, including all planets and theirsatellites, meteors, comets, asteroids, etc. is calledthe solar system.
We know,
Speed of light = 3 x 108 m/s.
Time = 1 year.
We have,
Distance travelled by light in 1 year = speed of light * time
=3 * 108m/s * 1 year.
= 3 * 108m/s * 365 * 24 * 60 * 60 seconds.
= 9.46 * 1015m.
= 9.46 * 1012km.
