Is there any proof?

We've known since ancient times that there were AT LEAST FIVE planets "out there". Namely: Mercury, Venus, Mars, Jupiter, and Saturn.
No one has ever doubted that those planets exist. They look like they are "stars" to the untrained eye...but they WANDER among the bulk of the stars, which real stars don't do.
Come 1543, the first publication states that our home Earth is a planet, just like the other five. BAM! At least 6 planets "out there"
Come 1781, Uranus is discovered. BAM! At least 7 planets "out there"
Come 1846, Neptune is discovered. BAM! At least 8 planets "out there"
Come 1992, PSR B1257+12-b is discovered. BAM! At least 9 planets "out there"
And the list continues to grow...to numbers as large as 555 confirmed planets as of April 2011.

"Thanks just seeing If people were dumb enough to answer"
People answering questions are generally regarded smarter than those asking...
but, in the spirit of the site - We've seen the other planets in orbit about the Sun for hundreds of years. Until recently, it was only a theory that other stars had planets - we'd not detected any until 1995, when the wobbling of a star indicated there must be a Jupiter-size planet orbiting it. Other planets, about 250 of them, were detected this way... In the last couple of years, the Webb Space Telescope has been staring at one section of the Milkyway, monitoring about 156,000 stars, and, if the light output from one dims for a bit, then regains it's magnitude, then that's a clear indication of a planet orbiting it. It was released a few months ago that Webb has found about 1200 planets, of all kinds of different sizes - about 84 of which are in the "habitable zone", where liquid water is possible.
The first possible *photograph* of a planet about a star was taken by the Keck telescope in Hawaii, in... May? June? of last year.
