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.
Between 1903 and 1918, the State again enlarged the canal by the construction of what was termed the Barge Canal, these locks of today are 328 feet long and 45 feet wide, with a depth of 12 feet of water over the mitre-sills, and can accomodate vessels 300 feet long and 43.5 feet wide.
