Question
In the attached plot of planetary mass versus orbital period for a sample of extrasolar planets, there are few planets in the circled region because _____.
A. planets rarely form with these combinations of mass and period
B. planets with these combinations of mass and period produce changes in stellar velocity that are too small to be detected
C. astronomers have not searched for planets with these combinations of mass and period
D. planets with these combinations of mass and period would have densities lower than could be explained even with a planet of pure hydrogen and helium

D. planets with these combinations of mass and period would have densities lower than could be explained even with a planet of pure hydrogen and helium
Thi stype of Planets have a low range of densities. if we compare the densiites of planet with respect to Pure hydrogen and helium. it would be lower than pure hydrogen and helium. so we state that this type of combination of mass and period have lower densities.
