Light's journey
The light you see tonight set out around the year 2002. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 418 thousand years.
The Sun seen from there
From a planet around 2MASSI J0835425-081923, the Sun would look like a star of magnitude 4.13, in the direction where our sky has the constellation Delphinus. It would be visible to the naked eye.
