    Bit of a debate as to where our solar system ends. Voyager is still a hell of a long way from interstellar space from what I remember reading.


    Can anyone answer me this please - I understand that from the trajectory and plane of this object that scientists/astronomers have deduced it's from beyond our solar system but can a dislodged kuipter belt or oort cloud object not take the same heading into the inner solar system as this object has?
    It's possible though rather unlikely that an Oort cloud body could interact with other bodies in the Oort cloud sufficiently to get shot through the solar system at escape velocity, but (a) those things tend to be icy, and this is metal and rock, and (b) it's a really weird shape, much more oblong than anything else we can see. It's most likely ejecta from a massive collision in Vega a long, long time ago.

    So far Voyager 1 has 'left the Solar System' by passing through the termination shock three times, the heliopause twice, and once each through the heliosheath, heliosphere, heliodrome, auroral discontinuity, Heaviside layer, trans-Neptunian panic zone, magnetogap, US Census Bureau Solar System statistical boundary, Kuiper gauntlet, Oort void, and crystal sphere holding the fixed stars.
