What Happened to Astraa?

When a fifth body named astraa was discovered in 18 forty five by k l. Hankey, it was classified as an asteroid. The term asteroid had actually been used by william herschel as a proposed classifier when palas was first found. But the discovery of the asteroid astraa really started a shift in thinking about the four previous discoveries that had happened in that belt. Soon more and more asteroids were identified in that same area where all of these objects existed. Eventually it dawned on people that what was actually there was an asteroid belt.
