Abstract
Sakurai's Object seems to be undergoing a very late Helium-flash, making it a unique observational event with very important implications for our understanding of late stellar evolution. We present the first individual distance determination: using the extinction method we have derived a distance of 1.1 kpc for the planetary nebula surrounding the star. This accurate distance will be a crucial step forward in our efforts to understand the nature and the evolution of Sakurai's Object.
Key words: ISM: planetary nebulae: individual: Sakurai's

stars: AGB and post-AGB
