Is the solar system unique ?

As advances in science and technology allow us to gain more and more information about planets orbiting distant stars the more we have come to appreciate both the similarities and differences between those systems and our own.
Since the first discovery of a planet orbiting another star in 1992, some 280 alien solar systems have been identified. Most look quite unlike ours, and for good reason. Planets are mainly spied by the way their gravity makes their host star wobble as they orbit. The smaller the planet, the smaller the wobble: lightweight planets like Earth produce effects too small to detect with current technology."

It sounds like solar systems that would look like ours are still non-detectable. Therefore it is way too early to posit that our solar system is unique.

Our solarsystem is unique because there is only one and only one solar system like ours:,

Our solarsystem is unique because there is only one and only one solar system like ours:, and that is based on what we know. there are more earthlike planets in other undiscoverd systems. Just look at our own. Mars and Earth had a simular history but something happened to Mars.....Did life evolve their? If it did, then we can expect to find more planets like our own. Solar systems are common place, it is just a fact of finding one that has planets of simular size and AU's from the primary star as earth and mars. and remember, mars does have temps in the 80's F range.
