No. They're slowing down by a very tiny amount. |
Ok, I know I'm gonna come across as pretty darn ignorant here, but why is this a mystery? Regardless of the crafts exceeding escape velocity for our solar system, they are still impacted by the Sun's gravity, right? I guess I'm left wondering "why
wouldn't they be slowing down???"
Isn't escape velocity just the speed needed get you away from a body at a velocity to where the gravitational affects of the body decrease at a greater rate than the speed of the craft itself, hense it'll never be pulled back?
