Chromosphere in sun
WebJun 16, 2024 · The Chromosphere is the layer we find between the distances of 250 and 1300 miles from the solar surface. The temperatures in this layer vary greatly, with the parts that are further from the solar surface being much hotter than the ones that are closer to it. Still, it does not compare to the temperatures that are reached in the Corona layer.
