Description

Comets are among the most beautiful astronomical objects in our sky, but brought fear to our ancestors when they appeared. Find out what comets are and where they come from in this lesson. What’s the difference between a comet an asteroid and a meteorite? Could one of these objects really hit the Earth? You will know after streaking through the solar system with this lesson.

This Course includes the following great BONUS LESSONS:

  • What on Earth is Astronomy?

  • Mini-Lesson: Eclipses

  • Mini-Lesson: Meteor Showers

  • Mini-Lesson: Aurora
