Answer:
Z is present outside the solar system.
Step-by-step explanation:
1 AU is equivalent to distance between the Earth and the Sun. It is approximately equal to 150 million kilometers.
1 light year is equivalent to distance traveled by light in one year.
1 light year = 63241.1 AU.
It is given that Y is at a distance of 59 AU and Z is 3.2 light years away from Earth.
This means that Y is closer to Earth and Z is very far. The solar system extends up to 122 AU. It means Z is present outside the solar system.
