'cause it's really very different that out tradicional asociation of a nice breeze these are just charged particles that are going out at super high velocities from the sun and i'm even going into the idea of the solar wind because to some degree they can help us with one definition of maybe the limits of the solar system and that's the limits of how far the solar wind is getting before it kinda comes in confrontation with the interstellar medium and this right here shows a depiction of that, so the oort cloud is way at least the edges of the dense part is way outside of this, as we saw this is just where voyager i and voyager il, if we wanted the orbit of sedna, it would be something like, the close part would be something over here and then it would go out but the oort cloud is much much further out, so if you look at this kind of view of the solar system as the extent of the solar wind it's much smaller than the oort cloud but it's still farely large, so this is right here this heliopause right here, and i got this from
