Question

Quizplus · Accepted Answer

We have been able to gather information on the orbits and masses of known exoplanets through various techniques such as radial velocity measurements and transit observations. Complete composition and precise masses are often difficult to determine and require more advanced technology and methods. Therefore, the best choice is A as it accurately reflects the available information we currently have on known exoplanets.
