Answer 1

Answer: D. 43,232 trillion kilometers

Step-by-step explanation:

We have the distance between Earth and V391 Pegasi b in light years:

`4570 ly`

And we have to find this distance in kilometers:

`4570 ly (9.46 trillion km)/(1 ly)=43232.2  trillion km`

Hence the distance in kilometers is:

`4570 ly=43232.2 trillion km \approx 43232 trillion km`
