Discovering the essential Universe by Neil F. Comins fourth edition
Extrasolar planets can be discovered by observing them indirectly by using microlensing, by observing the Doppler shift of the star due to the pull of the orbiting planet, by observing the periodic variation of the proper motion of a star, and by observing the periodic variation of the starlight due to the planet passing between that star and Earth, an event called a transit.
What else can I help you with?
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.
What methods do astronomers use to discover extrasolar planets?
Astronomers use various methods to discover extrasolar planets, also known as exoplanets. These methods include the transit method (detecting a planet as it passes in front of its star), the radial velocity method (detecting a wobble in a star's motion caused by an orbiting planet), direct imaging (taking pictures of exoplanets), and gravitational microlensing (observing the bending of light from a distant star due to a foreground planet).
The reason that most extrasolar planets are found close to their parent stars?
Most extrasolar planets are found close to their parent stars because current planet detection methods are biased towards detecting larger planets that are closer to their stars due to the limitations of technology. These close-in planets are easier to detect because they have a greater impact on their star's light or motion. As technology and detection methods improve, we are discovering more distant planets from their stars.
Where are ExtraSolar planets found?
Extrasolar planets are planets found orbiting stars other then our own.
Are there any extrasolar planets?
Yes. So far nearly 2,000 extrasolar planets have been discovered.

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.
Why do astronomers find it difficult to locate extrasolar planets with telephones?
Astronomers cannot locate extrasolar planets with telescopes because these planets are outside of our solar system and too far away for telescopes to directly observe. Instead, astronomers use indirect methods such as radial velocity and transit techniques to detect these distant planets.
Are there new discovered planets?
The current planets being discovered are called "Exoplanets" or "Extrasolar Planets" which means they are planets found outside of our solar system. New ones are constantly being discovered. We are currently getting closer to discovering one within the habitable zone of another star.

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 are most extrasolar planets found close to their parent stars?
Extrasolar planets are often found close to their parent stars because the methods used to detect them, like the transit and radial velocity methods, are more sensitive to detecting planets with short orbital periods (close-in planets). Additionally, close-in planets are easier to detect due to their stronger gravitational influence on their parent stars, making them more likely to produce observable effects.
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.
