This question is being awnswered in 2014 so it is as of 2014.1,653 dumbhead.
As of October 2021, astronomers have discovered over 4,500 confirmed exoplanets. This number continues to grow rapidly as new telescopes and technology are developed to detect more of these planets outside of our solar system.
Now we know of 861 exoplanets, with several thousand awaiting confirmation
There are planets outside our solar system known as exoplanets that might have Earth-like conditions, but none have been found that are identical to Earth. The search for Earth-like exoplanets continues using telescopes and technologies to explore the vast universe.
Planets outside our solar system are called exoplanets. Thousands of exoplanets have been discovered orbiting other stars in the Milky Way galaxy. They come in a variety of sizes and compositions, and many are quite different from the planets in our own solar system.
There are many planets that orbit stars other than the Sun. These are known as exoplanets and have been discovered in many different star systems throughout the galaxy. Some stars have multiple planets orbiting them, similar to our own solar system.

We hardly know yet. Planets other than those in our own solar system (called "extrasolar" planets or "exoplanets") have only been discovered in the last ten years or so. About a thousand are known, but astronomers feel there must be many, many more.

Earth is one of many planets. There are 8 planets in our own solar system and over 400 exoplanets found so far.

There is currently no confirmed sister planet to Earth. However, astronomers have discovered many exoplanets in other solar systems that share similar characteristics with Earth, such as being rocky and located in the habitable zone of their star.
Now we know of 861 exoplanets, with several thousand awaiting confirmation
Astronomers typically work eight hours a day.
many european explorers tried to find a trade route 2 asia, but many of them, well most of them never found it
There are many exoplanets that have been discovered during the last 12 years. See the sources and related links below for Wikipedia's article on exoplanetary systems. Most were found this millennium.
