GEOTAIL

• The Sun emits the solar wind, which is a continuous stream of charged particles (like electrons, protons, alpha particles etc). These particles are present in the upper  atmosphere of the Sun, called the Corona. science
• Since the Earth has a magnetic field, it obstructs this solar wind plasma.
• This interaction results in the formation of a magnetic envelope around Earth called magnetosphere.
• On the Earth side facing the Sun, this magnetosphere is compressed into a region that is approximately three to four times the Earth radius.
• On the opposite side, the envelope is stretched into a long tail, which extends beyond the orbit of the Moon. It is this that is called the geotail.
