How did Biden become VP? (naming of 2012 VP113)
This has to do with how minor planets obtain provisional names (see also Wikipedia). The year is divided into 24 half months, with a particular letter associated with each one. Each of these half-months has a number of cycles of length 25 depending on how many minor planets are discovered; a minor planet is assigned a letter corresponding to its order in the cycle, and the number of the cycle it is in. This means that the provisional name for a minor planet is, in general,

year+half-month+position in cycle+cycle number

2012 VP113 was discovered in 2012, in the first half-month of November (corresponding to the letter V) and was the 15th minor planet discovered in the 113th cycle that half-month.
