- A comet has a period of 71.3 years and moves in an elliptical orbit in which its perihelion (closest approach to the Sun) is 0.700 AU.

For the special case of a circular orbit, the semimajor axis equals the orbital radius. AUarrow_forwardGive me the solution for the problem. The correct answers are: A: -1.4 x 10-6 km/h. The comet's speed has been decreased by this amount. Hence, the effect is negligble. B: -6.7 x 10-8 km/h. The Earth's speed has been decreased by this amount. Also, the effect is negligble.arrow_forwardSuppose an asteroid has a tiny moon orbiting around it (which does occur).
