In the sky
A telescope is needed to see it: its apparent magnitude is 12.34. Visible from the whole Southern Hemisphere and north to latitude 67° N. South of latitude 67° S it never sets. It stands highest at midnight in April, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1335. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12 million years.
The Sun seen from there
From a planet around HATS-37 A, the Sun would look like a star of magnitude 11.46, in the direction where our sky has the constellation Pisces. It would be invisible to the naked eye.
