Its expected radius is about 0.12 solar radii which is approximately 120 percent of the radius of Jupiter (largest planet in our solar system). It has the mass of about 0.1 solar masses which is very close to the lowest possible mass i.e. 0.07 solar masses. 0 Login to Reply Share Share Share on Facebook Share on Twitter Share on Google plus Share on WhatsApp Leave an answerCancel replyYou must login or register to add a new answer.
