Consider the following diagram of a comet's orbit:
What is illustrated about comets here?
◦ Ionized cometary gases being pushed away from the coma by the pressure of the solar wind of charged particles coming from the sun emitted by the Sun.
◦ Comets are like planets and revolve in regular orbitals around a single star.
◦ Comets are hotter than the Sun which is why they have such a different appearance from the Sun.
◦ The part of the comet where comets are most concentrated is in the part of the comet farthest from the sun.
