In the sky
Visible to the naked eye under a dark sky (apparent magnitude 5.86). Visible from the whole Southern Hemisphere and north to latitude 76° N. South of latitude 76° S it never sets. It stands highest at midnight in March, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1590. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 7.7 million years.
The Sun seen from there
From a planet around HIP 53778, the Sun would look like a star of magnitude 10.46, in the direction where our sky has the constellation Pegasus. It would be invisible to the naked eye.
Position, brightness and colour from the HYG / AT-HYG catalogue; temperature, luminosity, radius and mass are approximate values computed from these observations.
