Does our solar system appear to be unique or are there many solar systems similar to ours in the universe?

The answer to the question "Does our solar system appear to be unique or are there many solar systems similar to ours in the universe?" is that there is an abundance of other solar systems like ours in the universe. The Kepler program, for example, has discovered over 1000 potentially habitable planets orbiting Sun-like stars. These planets are kept in orbit by their respective star, just like Earth is kept in orbit by the Sun. The Gliese program has also revealed the existence of many other planets beyond our solar system. In summary, our solar system is not unique, and there are many other solar systems in the universe that resemble ours in terms of the presence of planets orbiting around a Sun-like star.
