Can the solar flares affect the Earth or anything else besides the Sun?
Solar flares can have considerable affects on the upper atmosphere and ionosphere. Solar flares emit a lot of X-rays, which bombard the atmosphere, heating it and creating ions from the atoms of the air. The heating can cause the atmospheric density to increase, causing more drag on low altitude satellites. The creating of a lot of extra ions changes the characteristics of the ionosphere, affecting varous kinds of radio transmissions. Dr.
