'medium', that's just kind of out there, after this point it's not being ejected out anymore it's just kind of, there's this kind of 'pause' there, i guess you could say and voyager i and voyager ii have essentially gotten pretty close to people believe, that 'pause' over there, and that's one view of the edges of the solar system there's never going to be any hard edge to it, another view would be something like the oort cloud, you know, the area where you have the still objects out there and this is all, actually we haven't directly observed objects in the oort cloud, we think they're out there, and then maybe the most abstract definition would be the significant influence from the sun's gravitational pull, so all of those ways are to imagine the extent of the solar system, but they all kinda leave a gray area for what is and what is not in the solar system, but my whole point here, what i wanna do is start explaining a little bit outside of the solar system and just give you a sense of the scale as we just go to the closest start so if we go right over here, this shows our local neighbourhood from a stellar point of view, and even though this stars look pretty big, if you actually were to draw, this is our solar system right here, but clearly, oh and you might be saying 'oh that's the sun', no, the sun if you were to draw it here, it wouldn't even make up one pixel, in fact the entire orbit of pluto, everything inside it still wouldn't make up one pixel on the screen right here, what we see right here, which is a radius it's roughly a radius of about, give or take, a light year, this is roughly maybe the radius of the oort cloud, and we saw in the last video how huge that was especially relative to the radius of, say, pluto's orbit, which is roughly
