The journey sliders give you the full sweep at once; this page is for pinning two specific things side by side. Pick any two stops with concrete sizes and you get the exact ratio between them — including the kind of number that makes the difference feel real (a Sun is roughly a hundred Jupiters across; a Jupiter is roughly eleven Earths; an Earth is roughly four Moons). Sharing the URL of any pairing gives the other person the same view.
