    Answer:

    2\ ly=1.89\times 10^{16}\ m

    Explanation:

    The question says that, “The closest star to the earth is 2 light years away. Calculate this distance in SI units”.

    Given that,

    The distance between the closest star and the Earth is 2 light years.

    The SI unit of distance is m. It means we need to convert light years to meters. We know that,

    1\ ly=9.461\times 10^{15}\ m

    2 light-years means,

    2\ ly=2\times 9.461\times 10^{15}\ m\\\\=1.89\times 10^{16}\ m

    So, the required distance is equal to 1.89\times 10^{16}\ m.
