In the sky
A telescope is needed to see it: its apparent magnitude is 13.36. Visible from the whole Southern Hemisphere and north to latitude 64° N. South of latitude 64° S it never sets. It stands highest at midnight in March, the best time to observe it.

Light's journey
The light you see tonight set out around the year 305. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 31 million years.
The Sun seen from there
From a planet around TOI-2981, the Sun would look like a star of magnitude 13.44, in the direction where our sky has the constellation Pegasus. It would be invisible to the naked eye.
