I want to know which books I can pick up to help me with the physics and a good telescope for just stargazing.
Help?
I’m on a budget and I have prior knowledge with physics..
thanks?
Comet Hale–Bopp has a perihelion distance of 3.45 × 107 km, and an
aphelion distance of 3.49×1011 km. How long does it take Comet Hale–Bopp
to orbit the Sun once in years?
If there were two black holes that were identical in size and weight, and they were near eachother… what do you imagine would happen? Would they orbit around eachother? Form as one? or work completely independent?
