Question

planets orbit the sun in the shape of a perfect circle. the sun is always found at one of the two foci when looking at an orbital diagram. comets usually have very eccentric orbits and take a long time to orbit around the sun. planets are closest to the sun during aphelion and furthest away during perihelion.

Explanation:

• Planets orbit the Sun in elliptical paths, not perfect circles.
• According to Kepler's first law, the Sun is at one of the foci of the elliptical orbit.
• Comets have highly eccentric orbits and long orbital periods.
• Planets are closest to the Sun at perihelion and farthest at aphelion.

Answer:
