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.
Why has mars been the planets most studied by telescopes?
there might be life in mars
How many solar systems have exoplanets?
It is too premature to give percentages. Several hundred planets have already been found around other solar systems; but so far, mostly giant planets have been found, most of them larger than Jupiter.It is too premature to give percentages.

Can you see other planets outside our solar system. Or are they all just stars. How about if you use a telescope?
You cannot see planets outside our solar system with the naked eye. And, only a rare few can be seen with the most powerful telescopes. Most are detected by way of indirect measurements -- by observing their effect on their suns (stars).
Can you see exoplanets?
Not directly. Exoplanets are generally too small and dim to be seen directly, at interstellar distances, especially since they are hidden by the glare of their parent star. Only a handful of planets have been imaged directly, and most of those were detected using infrared rather than visible light.
Is the solar system the only system in out galaxy?
No, it's thought that most of the 200 billion or so stars in our galaxy are solar systems themselves, with planets in orbit around them. These are know as exosolar planets, many have been identified through their gravitational effects on the stars.
What other star has planets orbiting around them?
We believe that most stars have planets. The first star PROVABLY detected to have a planet was Gamma Cephei.

What planets are most massive than earth?
In our solar system, the planets Jupiter, Saturn, Uranus and Neptune are more massive. There are over 300 extra-solar planets known to be circling other stars; in most cases, only very massive planets can be detected at such ranges. It is likely that other smaller planets also exist, but we have no indication of that so far.
How far are the planets from the Milky Way?
Most planets that have been discovered are in the Milky Way
Why is it that our solar system has so many planets and dwarf planets while most of the discovered exosolar systems have a lesser number of planets?
Actually, we don't know for sure that other systems don't have as many dwarf planets. Even with the acceleration of advances in telescope technology, spotting other solar systems is not easy, and the pictures are seldom definitive. Aside from that, our system is an unusual one in many ways besides the apparently extraordinary number of planets. There are many theories about why that might be, ranging from age to chance. Perhaps the most satisfactory answer that can be given at this time is that our system is in a location that allows it to collect mass more rapidly than other systems.
What are the Atmosphere types of the planets?
Most planets that have so far been discovered have had gaseous atmospheres.
How much time from the earth to the most far known planet?
Many extra-solar planets have been detected, some many light years distant, at our present stage of technology it would take many millions of years to reach them
What planet resembles extrasolar planets most?
About 100 extrasolar planets are thought to have been discovered. All are giants and probably most resemble Jupiter
Why has mars been the planets most studied by telescopes?
there might be life in mars
