In the sky
A telescope is needed to see it: its apparent magnitude is 24.02. Visible from the whole Northern Hemisphere and south to latitude 61° S. North of latitude 61° N it never sets. It stands highest at midnight in January, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1993. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 584 thousand years.
The Sun seen from there
From a planet around WISEA J083011.95+283716.0, the Sun would look like a star of magnitude 4.85, in the direction where our sky has the constellation Microscopium. It would be visible to the naked eye.
