The solar system includes moons (and some of those moons have moons), supernova explosions, comets, meteors, asteroids, and plain old space dust. To be sure, there are more objects in our solar system, some of which have yet to be discovered.
The canal was not complete in 1825, however. Many years after opening, people decided the canal needed to be a bit wider and larger. People wanted to connect more waterways to the Erie Canal in order to get full use out of the canal system. So, between 1836 and 1862 the Erie Canal was made wider and was connected to other canals.
When finally completed on October 26, 1825, it was the engineering marvel of its day. It included 18 aqueducts to carry the canal over ravines and rivers, and 83 locks, with a rise of 568 feet from the Hudson River to Lake Erie.
