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.
Besides the tremendous impact of construction and opening of the Erie Canal, it would be difficult to discuss the incredible growth and development of New York (a State that increased in population from 1820 to 1900, from 1.4 million people to almost 11 million people) without highlighting the role played by railroads.
