What are the two main differences between extrasolar planetary systems discovered to date and our Solar System?
A) extrasolar planets tend to be more massive and dense than Jupiter
B) extrasolar planet orbits tend to be closer and more circular than in our Solar System
C) extrasolar planet orbits tend to be more eccentric and inclined than in our Solar System
D) extrasolar planets tend to be bigger and denser than Jupiter
E) extrasolar planet orbits tend to be closer and more eccentric than in our Solar System
The composition of a planet's atmosphere can be measured during a transit by analyzing
A) the wobble in a star's position on the sky.
B) the excess absorption of starlight at specific wavelengths.
C) the excess emission of starlight at specific wavelengths.
D) the length and depth of the dip in light during the transit.
E) the amplitude and period of the star's motion.
