摘要：

Using VLA data from epochs separated by 2.75 yr, we measured the angular expansion of the planetary nebula NGC 6302 to be 1.75 +/- 0.3 milliarcseconds yr-1. Adopting an expansion velocity of 13 km s-1 for the ionized gas and a simple model for the structure and dynamics of the nebula, we estimate a distance of 1.6 +/- 0.6 kpc for NGC 6302.
