Not sure if space has that much stuff in it outside the heliosphere... Some numbers here: https://en.m.wikipedia.org/wiki/Interstellar_medium https://en.m.wiki

  It will still be travelling at that speed when entering the corresponding area of the target system. If it could survive, it would be interesting to know what kind of observations could be made by a single-chip sensor travelling at that speed. No planetary close-ups surely.

    Good point. And yeah I wonder how accurate its trajectory would be after travelling multiple light years. Cool engineering problems!

    This is a fascinating read: https://arxiv.org/pdf/physics/0610030.pdf https://arxiv.org/pdf/physics/0610030.pdf
