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.
ask ur professor
Extrasolar planets are planets found orbiting stars other then our own.
light from the they orbit makes it difficult to locate extrasolar planets with telescope
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.
Both exoplanet and extrasolar planet are planets that are outside the solar sysytem.

Yes. So far nearly 2,000 extrasolar planets have 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.Yes, hundreds of "extrasolar" planets, i.e., planets outside our own Solar System, have already been discovered.
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.

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

Current detection methods are only capable of detecting planets which are close to their parent star. This may not be a trend, only statistically biased.
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.
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.
