Tails can be up to 150 million km (93 million miles) long, and they always point away from the Sun because of the force of the solar wind. ♦ Plasma tails, or ion tails, appear bluish and straight and narrow, and are formed when solar wind forces ionized gas to stream off the coma. Dust tails are wide and curved, and are formed when solar heat forces trails of dust off the coma; solid particles reflecting the Sun's light create their bright yellow color.
