The picture below shows Halley's Comet, which has an elliptical orbit around the Sun and can be seen from Earth every 75 to 76 years. Why does Halley's Comet travel in an elliptical orbit around the Sun?

• the force of gravity between the comet and the Sun influences the comet’s motion.

• it has a negative magnetic field that is attracted to the Sun's positive magnetic field.

• it is attracted to the outer planets that sling it toward the Sun.

• the rotation of the solar system creates winds that push it around the Sun.
