Heya,
Light year is the unit by which the astronomer calculate the distance between two celestial bodies in the space. It is the distance travelled by light in one year of time. One light-year is equal to 9,500,000,000,000 kilometers.
Alpha Centauri is the star which is second closest to the earth after the sun. It is 4.367 light years from the earth.
Hope this helps you...:)
