- exoplanets similar to Earth? Telluric exoplanets with atmosphere?
- Alright: exoplanets around a single star have been discovered.
But are there also discovered exoplanets in multiple stellar systems? (binary, ternary, ...)

New ones are constantly being discovered.
As of June 2006 the number is 173.

The discovery of exoplanets is highly dependent on the method used. As of last month, approximately 200 'exoplanets' were reported. That number is likely to increase rapidly.
I do not know if there's evidence for exoplanets in multiple-star systems.

Not sure about planets similar to earth. We have no real way to check on atmosphere for the most part. Over 100 planets that are gas type giants have been discovered, but that's using a technique that detects the wobble in a star caused by the gravitational disturbance created by these planets. In the next year or so there is new technology coming out that should allow us to pinpoint smaller planets within distant solar-systems.

Over 30...there's a new one cropping up every few weeks.
Similar to Earth? None.
Yes, there's also discovered exoplanets in binary systems. Ternary? Don't know. Wiki it.

properly over the subsequent sort of years we will be passing by potential of the galactic airplane. and there is a lot of airborne dirt and dust and debris there. regardless of the indisputable fact that the time period stellar wonder wave makes no sense right here. that's only a wonder wave on a stellar floor. Now heliosheath wonder is a distinct tale.

The means used to detect exoplanets requires that the planets either be large enough to disrupt a star's radiation, or massive enough to disrupt a star's gravitational field.
Earth is not large enough to disrupt our Sun's radiation, or massive enough to disrupt its gravitational field, so we cannot detect planets similar to Earth... yet.
