We restrict our analysis to planets with directly measured masses and radii, which comprise a total of 70 planets: 30 singles and 40 multis in 19 systems. We compare the bulk densities for the full sample, which includes planets ranging in size from $0.52 R_{\\oplus}$ to $12.8R_\\oplus$, and find that single planets have significantly lower densities on average than multis, which ","authors_text":"Anusha Pai Asnodkar, B.
