Before 1950, hurricanes were given numbers in order of their formation date, e.g. Hurricane One, Hurricane Two, Hurricane Three, etc.
In the year 1950, we started giving hurricanes proper names like Able, Baker, Charlie, Dog, and other names.
Look, I don't know about you, but I'm tired of having to tell my friends about 1SWASP J140747.93-394542.6 b, it's just a mouthful to say. Do you think that we should give exoplanets actual names, the way we do with hurricanes?
