Fly through the corona of what is by far the largest, most massive, and most significant object in the solar system: the Sun. In fact, at 99.9 percent of the total mass of the system, you could say the Sun IS the solar system. With its gravity, heat, light, magnetic fields, and plasma storms, learn how the Sun affects every object in the system-and how we are in a race to learn more about coronal mass ejections before one destroys trillions of dollar's worth of electronics on Earth.
