@Rohit Bains.
The distance between the sun and earth is 149.6 million km and the distance between the earth and star is 9.46 million km. so that light from the stars takes more time to reach earth than the sun. And distance is also responsible for the twinkling of the stars, light from the starts gets refracted by air medium in the atmosphere layer. So stars may twinkle while we see.
