Kepler-79

(KOI-152, 2MASS J20020411+4422536)
(star with four super-puff planets)

Kepler-79 is a star with four extra-solar planets noted for being super-puffs (low-density planets, apparently super-Earths with atmospheres much more extensive than Earth's). Characteristics:

planet mass(Earth) radius(Earth) orbital radius(AU) orbital period(days)
Kepler-79b 10.9 3.47 0.117 13
Kepler-79c 5.9 3.72 0.030 27
Kepler-79d 6.0 7.16 0.025 52
Kepler-79e 4.1 3.49 0.012 81

For comparison, a planet of Earth's density but three times Earth's radius would have 27 times Earth's mass. Note that the orbital periods of the planets are effectively observed, but the other characteristics are derived through analysis and have considerable uncertainty, particularly their masses.
