Odds Of Solar Flare Hitting Earth 2025. Solar flares aren’t rare, but they do rarely hit earth. During the last period of high solar activity in 2012, scientists spotted a couple of coronal mass ejections that crossed the earth’s orbit.

Solar activity is expected to maintain elevated levels throughout 2025, marking a significant phase in solar cycle 25. The visible effects here on earth, are the intense aurora or ‘northern lights’ we sometimes see.
