Answer 2

The light emitted by it today will be seen after  15 years.

Step-by-step explanation:

• Given data

        Distance between star and earth = 15 Light year

• One light year :- It is distance travel by light in one year.

                                                 OR

• We can also say time taken by light to cover distance one light year is 1 year.

• Now come to question, it is given that distance between star and earth is 15 Light years. So time taken by light to travel from star to earth is 15 years.
• Largest unit of distance is Parsec
• 1 parsec = 3.6 × Light year
