NASA says the Sun goes through a natural solar cycle approximately every 11 years, which is marked by the increase and decrease of sunspots

The greatest number of sunspots in any given solar cycle is designated as “solar maximum”. The lowest number is “solar minimum”

The current solar cycle is the 25th since the records began in 1755 and started in 2019
