Hi there! I'm new and I have two questions if anyone would care to help.
Question 1: From the perspective of the Sun, are all the planets at the same elevation? By that I mean if all the orbits were synchronized, would they all be in a straight line or would some planets be "higher" or "lower" than others?
Question 2: Again from the perspective of the Sun, we always talk about going further "out" with probes and such, but what about going "up" or "down" on the z-axis? Is there anything to explore in that vein?
