Although there's always luck involved, it was discovered by the Catalina Sky Survey, a survey specifically designed to spot near-earth objects.
Their main telescope has a very large field of view (20 square degrees), and takes only 30 seconds per exposure, giving it many chances to get "lucky".

I would have a hard time believing "not at all". Vaguely related this is my favorite amateur astronomer spotting accident ever, capturing supernova an hour before it happened which hasn't been done before: https://www.popsci.com/amateur-astronomer-photographs-birth-supernova/ https://www.popsci.com/amateur-astronomer-photographs-birth-... makes me wonder when the sky becomes so difficult to see through if we are going to lose all that enthusiastic effort
