Question
What is the name of the outermost layer of the
Sun?Solution
Corona is the outermost layer of the Sun. It experiences a very high temperature, about one million degrees Celcius. It starts at about 2100 kmabove the photosphere. Corona isn't visible from the earth (except during solar eclipse). The corona does not have an upper limit.
