- What is the asteroid's orbital radius? What is the asteroid's orbital speed?Annual meteor showers occur when the Earth passes through the orbital path of acomet. The intensity of these showers vary from year to year. Which of the following may bethe reason for this? Group of answer choices - Meteor showers are not caused by comet debris - Sun's temperature - en distribution of debris along comet's orbit - Earth's rotation axisAn asteroid orbits the Sun in a 2:1 resonance with Jupiter.
