Humans have been observing comets for thousands of years. Though comets appear infrequently, when they do appear, they can be visible to the naked eye at night as a bright white star with a long, misty white tail trailing behind it.
On November 12th, 2014, the Philae lander successfully landed on comet 67P after a 10-year, 3-billion-mile voyage aboard spacecraft Rosetta. The event marks the first-ever landing of a space vehicle on a comet. Both Rosetta and Philae are loaded with scientific equipment for measuring the composition, gravity, appearance, and surface of the comet, opening a new chapter in our scientific understanding of comets and our early universe.
But what is a comet, anyway?
What do we know about their surface, appearance, size, tail, color, brightness, age, movement … and even their smell? In each of the interviews below, scientists (some of whom were part of the Rosetta mission) describe various comet characteristics. As you listen to these interviews, take notes as the scientists describe what a comet is like. You can use this comet characteristics graphic organizer to help you write down these descriptions.
You will then incorporate your comet descriptions, literally, into your own text illustration of a comet. A text illustration uses actual descriptive text to form the shapes and objects in a drawing. This is a great way to quickly visualize all the information you’ve learned about comets.
