In the sky
A telescope is needed to see it: its apparent magnitude is 9.62. Visible from the whole Southern Hemisphere and north to latitude 33° N. South of latitude 33° S it never sets. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1463. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 10.0 million years.
The Sun seen from there
From a planet around HD 148797, the Sun would look like a star of magnitude 11.01, in the direction where our sky has the constellation Camelopardalis. It would be invisible to the naked eye.
