That is a rediculous answer.

The current Guide Star Catalogue (GSC-II) contains 945,592,683 stars out to magnitude 21. That's almost a billion.

How does a a supernova get its name?

SN is the beginning of the supernovas name, self explanatory because it stands for Super Nova. The 4 digit number is the year it was discovered. The letter at the end is what order it was discovered in. For example, SN 2012A is the first Supernova discovered in 2012. SN 2012L would be the 12th discovered in 2012. Lately it has become more common that double letters are needed, like SN 2012AA or AB with the ammount of supernovas we discover with new technology.
