I'm writing a sci-fi novel (takes place in the future and in space) and I got a few questions..
-How long is a lightyear?
-How many lightyears away is Pluto?
-What is the average speed of a spaceship?
-What's a good futuristic year? Currently, I use 2053, but is that too soon?
Thank you in advance!! My book's called "In and out of space." (Yes, very creative. XD)
