Answer:
The Sun sends out two types of particles that can have negative effects in the Solar System: solar wind and solar flares. Solar wind is a stream of charged particles that is constantly emitted from the Sun's atmosphere. These particles can affect the orbits of planets and other objects in the Solar System, and can also interfere with satellite and radio communications on Earth. Solar flares are intense bursts of radiation that are emitted from the Sun's surface. They can cause disruptions to satellite and radio communications, and can also pose a danger to astronauts and other people in space.
Solar activity, including the emission of solar wind and solar flares, varies over time. The Sun follows an approximately 11-year cycle of activity, during which the number of sunspots and other indicators of solar activity rise and fall. At the peak of the cycle, the Sun is more active and is more likely to produce solar flares and other forms of solar activity. At the low point of the cycle, solar activity is lower and the Sun is less likely to produce these effects.
