Answer:

$2\ ly=1.89* 10^(16)\ m$

Step-by-step 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,

$1\ ly=9.461* 10^(15)\ m$

2 light-years means,

$2\ ly=2* 9.461* 10^(15)\ m\\\\=1.89* 10^(16)\ m$

So, the required distance is equal to
$1.89* 10^(16)\ m$ .
