Why is it so difficult to see an accurate picture of the solar system on a screen or in a book?
Because of the great distances between planets, and the planets relatively small sizes compared to those distances, it’s practically impossible to create a visual representation on a screen or the page of a book that realistically represents the sizes of the planets and the distance between them.
What is the main reason it is so challenging to detect extrasolar planets quizlet?
Why is it so difficult to take pictures of extrasolar planets? Their light is overwhelmed by the light from their star. Suppose you are using the Doppler technique to look for planets around another star.
Why is it so difficult to image an Earth sized planet directly quizlet?
Which of the following is a major reason why it so difficult to obtain direct images of extrasolar planets? The light of the planets is overwhelmed by the light from their star. only a small fraction of stars that have planets.
How do we think hot Jupiters formed?
How do we think hot Jupiters formed? Hot Jupiters formed beyond the frost line, as in our solar system, and migrated inward due to interaction with the solar nebula. We think that it is possible for planets to migrate through their disks because of interactions with the gas in the disk.
How does direct imaging method work?
Direct imaging uses infrared wavelengths to observe planets. This works because at infrared wavelengths a star like the Sun is only 100 times brighter than Jupiter, compared to a billion (109) times brighter at visual wavelengths.
Which of the following makes it very difficult to detect planets around other stars quizlet?
Why is it so difficult to detect planets around other stars? that typical stars are a billion times brighter than the light reflected from any of their planets make it very difficult to detect extra-solar planet s.
Why are hot Jupiters easier?
Hot Jupiters are the easiest extrasolar planets to detect via the radial-velocity method, because the oscillations they induce in their parent stars’ motion are relatively large and rapid compared to those of other known types of planets.
Why are most extrasolar planetary systems detected by Doppler method so different than ours?
Why are most extrasolar planetary systems so different than ours? It is easier to detect planets that are massive and close to their stars, and harder to detect systems like our own. It will search for the dip in a star’s brightness when an Earth-like planet transits (passes in front of) the star.
