Outline of the Solar System
Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets (including Earth), with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
List of solar storms
Active stars produce disturbances in space weather with the field of heliophysics the science that studies such phenomena; itself primarily an interdisciplinary combination of solar physics and planetary science (long-term space weather patterns comprise space climate). In the Solar System, the Sun can produce intense geomagnetic and energetic particle storms capable of causing severe damage to technology including but not limited to large scale power outages, disruption or blackouts of radio communications (including GPS), and temporary to permanent disabling of satellites and other spaceborne technology. Intense solar storms may also be hazardous to high-latitude, high-altitude aviation and to human spaceflight. Geomagnetic storms are the cause of auroras. The most significant known solar storm occurred in September 1859 and is known as the "Carrington event". The damage from the most potent solar storms is capable of existentially threatening the stability of modern human civilization, although proper preparedness and mitigation can substantially reduce the hazards. Proxy data from Earth, as well as analysis of stars similar to the Sun suggest that it may be capable of producing so called superflares, those which are much larger than any flares in the historical record (as much as 1000x stronger every 5000 years), but it contradicts to the models of solar flares and to the statistic of extreme solar events reconstructed using cosmogenic isotope data in terrestrial archives . The discrepancy is not yet resolved and may be related to a biased statistic of the stellar population of solar analogs Although there is proxy evidence, interpretation of such proxy data remains unresolved..
