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.
On October 25, 1825, the entire length of the Erie Canal was complete. The canal consisted of 85 locks to manage a 500 foot (150 meter) rise in elevation from the Hudson River to Buffalo. The canal was 363 miles (584 kilometers) long, 40 feet (12m) wide, and 4 feet deep (1.2m).
