What's your favorite subject in astrophysicists

Thanks for your answer and I had no idea that the suns gravity extends that far thanks for the information (:

The biggest black hole I know of has 32000000000 (32 billion) soler masses. How far would the gravitational effect of it reach?

I was watching a show about the sun and it said the suns gravity extends for at least two light years. then I watched a different documentary and it said that the gravity of the sun extends for one light year. What is the truth behind this?

I'm going to buy a new telescope. I have not used a telescope yet, but I what to see nebula, deep space objects and the closest superior planets in detail and my budget is about $500. What would you recommend? Refractory is my best bet, correct, but magnification and lens length would be a good...

if there was a black hole that ways as much as the sun how big would it be?

is the smallest black hole ten miles wide or are there smaller black holes
