For a planet to be affected by a blob of material being ejected by the Sun, the planet must be in the path of the blob. The sun flings out solar wind particles in much the same manner as a garden sprinkler throws out water droplets. The solar wind is formed as the Sun's top layer blows off into space. It carries magnetic fields still attached to the Sun. Streams appear to flow into space as if they are spiraling out from the Sun, as shown in this figure.
Planets have to be in a stream's path to be affected.
