Answer to Question 1

Titan, Europa, Ganymede, and Enceladus

Answer to Question 2

Because the planet passes directly in front of its star, it blocks some of the star's light. The more light that is blocked, the bigger the planet must be, so by measuring how much of the star's light is lost during such transits we can learn the planet's diameter. The time between transits reveals the planet's period, the size of its orbit and possibly its mass. Combining the mass and size of the planet can yield its density.
