In the sky
A telescope is needed to see it: its apparent magnitude is 11.55. Visible from the whole Southern Hemisphere and north to latitude 20° N. South of latitude 20° S it never sets. It stands highest at midnight in November, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1111. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 16 million years.
The Sun seen from there
From a planet around TOI-2238, the Sun would look like a star of magnitude 12.07, in the direction where our sky has the constellation Ursa Minor. It would be invisible to the naked eye.
