It was not good astronomy. It was EXCELLENT astronomy!

In addition to suggesting the existence of external galaxies, Kant recognized that the Milky Way's brightest component is a disk. He also correctly explained why Mars is smaller than Earth: because Jupiter interfered.

Incidentally, Kant was not the first to suggest the existence of external galaxies. English architect Christopher Wren did so in 1657.
