By the transit process,what characteristics of nearly edge-on extrasolar planets to our line of sight can be determined?
A) The planet's diameter
B) The planet's atmospheric composition
C) The planet's temperature
D) All of the above

Question

Quizplus · Accepted Answer

By observing the transit of an extrasolar planet, scientists can actually determine its diameter by measuring the amount of light blocked by the planet as it passes in front of its star. By examining the wavelength of light passing through the planet's atmosphere during transit, scientists can also determine its atmospheric composition. Finally, by monitoring the brightness of the star before, during, and after the transit, scientists can track changes in the planet's temperature as it orbits around its star. Therefore, all of the above characteristics can be determined through the transit process.
