With that definition once you pass the orbit of the last planet your have exited the solar system (although since the orbits aren&apos;t circular and they all are in the ~same plane there sure is still some room for debate about the exact border of the solar system) - and consequently when pluto was excluded the size of the solar system shrank.&lt;p&gt;I don&apos;t imagine that my simple view of the matter is in any way accurate, but considering that noone seems to know where och what is supposed to happen when you leave the solar system, what are we then waiting for?&lt;p&gt;That something odd is happening and then, aha! That must be it! This is from now on the definition of the end of the solar system?&lt;p&gt;Sure, there might be a border where cosmic rays from outside of the solar system greatly increase etc. but does that have to coincide with the definition of the solar system?</text></comment>

If it keeps going at its current speed of 17km/s, it should reach the nearest star by the year 75,787.</text></comment>
