Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
Why do astronomers find it difficult to to locate extrasolar planets with telescope?
light from the they orbit makes it difficult to locate extrasolar planets with telescope
Why are extrasolar planets more massive than earth?
Most of the known extrasolar planets are more massive than Earth because massive planets are easier to detect. We have detected planets smaller than Earth.
What is the difference between exoplanet and extrasolar planet?
Both exoplanet and extrasolar planet are planets that are outside the solar sysytem.
Why can't hubble be used to detect extrasolar planets?
It actually can and is used to detect extrasolar planets, mostly through watching their transits, where they move in front of the star and block some of its light.
How many basic planets are there?
Currently there are 353 known extrasolar planets (that is to say, outside of our solar system), but it is unknown how many planets exist in the universe.

How many planets have been found?
There are 464 extrasolar planets, and 8 planets within our Solar System. This makes a total of 470 known planets.
Is there other solar systems around the stars?
Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.
What has the author J-P Beaulieu written?

What planet resembles extrasolar planets most?
About 100 extrasolar planets are thought to have been discovered. All are giants and probably most resemble Jupiter

The reason that most extrasolar planets are found close to their parent stars?
The reason that most extrasolar planets are found close to their parent stars is that the amount and frequency of the star's motion are both higher in these planets.
How many civilisations in the universe?
So far, we know of one planet that has life on it: our own. Anything else is speculation. It is possible there is life - and perhaps civilizations - on other planets; we simply didn't have a good chance to watch other planets, and especially the "extrasolar" planets - from nearby, to either confirm or reject this idea.
