Some interesting notes from this map of the solar system:
- This map is dated 1846. This date seems plausible as it (mostly) coincides with the discoveries of planets and satellites in the map. I suspect that it may have been engraved slightly earlier as it does not include Astraea as a planet (discovered in 1845) but does include the other asteroids Ceres, Pallas, Juno and Vesta (all discovered before 1810).
- Vesta, Juno, Ceres, and Pallas are included as planets. They were discovered in the early 19th century (1801 to 1807).
- Neptune and Pluto are not included having been discovered in 1846 and 1930, respectively.
- Uranus is also called Herschel (after Friedrich Wilhelm Herschel who discovered it in 1781). It is shown with six moons even though the sixth moon was not discovered until 1985.
- Saturn is shown with seven moons. The last moon having been discovered in 1789, the next (Hyperion) was not discovered until 1848. (Saturn is currenlty known to have at least 47 moons.)
- Jupiter is shown with four moons. The first four were discovered in the 17th century and the fifth was not discovered until 1892. (Jupiter is currenlty known to have at least 63 moons.)
