In this lesson, we are . going to be comparing comets, meteors, and asteroids which are found . in the Solar System. . Essential Question:. What is the difference between a comet, meteor, . and asteroid?. Comets and Their Significance. In the past, people dreaded comets as omens of human disasters such as wars or famines.. Today we know that . comets. are icy members of our solar system that have highly elliptical orbits.. What will we bring back? . Paula Lindgren.

Describe . the focus of comparative . planetology. and discuss its importance to solar system studies. .. Comparative . planetology. is . the approach we use to study and understand our solar system.

An asteroid is a rocky object up to kilometers wide that revolves around the Sun.. . What are comets made out of? . A. . comet is a frozen mass. Ellen Howell (Arecibo Observatory) and Amy Lovell (Agnes Scott College). Hyakutake. Comets: where do they come from?. Icy bodies ejected during giant planet formation. Remnants of early solar system. Chapter 20. A loose collection of ice, dust and small rocky particles. Orbits are very long and narrow ellipses. Comprised of 2 parts: Head and Tail. Originate from either Kuiper belt or . Oort. cloud. Facts. Comets, like asteroids are small celestial bodies that orbit the sun. However, unlike asteroids comets are made mostly of frozen ammonia, methane or water, and contain only small amounts of rocky material.. Comets and asteroids are particularly interesting because of their resemblance to . planetisimals. : the building blocks of the Solar System.. Asteroids are rocky, and most are found between Mars and Jupiter.. .. They have also been called . planetoids. , especially the larger ones. Formation.
