Our Galaxy has a diameter of about 30 kpc, and the thickness of its disk is 600 pc. It is known that about 5 supernovae break out in the Galaxy in 100 years. How often can a supernova explosion occur in the close vicinity of the solar system (in an area with a radius of 100 pc)? Consider that the density of stars in the disk is the same everywhere.

About one supernova every 2 million years.
