Comets and Asteroids Assignment

What are comets?

  • Comets are objects that enter the solar system while orbiting the sun.
  • These structures consist of ice, dust, and the other debris from space.
  • Comets were formed about 4.6 billion years ago when the solar system was created and that is why they have so much debris.
  • Comets go through processes of "orbiting the sun" and "planetary orbiting". When the comet orbits the sun, it is at a great distance and is like a "dirty snowball". As the comet gets closer to the sun, it vaporizes and goes around the sun. When comets are on a planetary orbit, they travel on a path the is more like a stretched-out circle called an ellipse.
  • When comets are far away they tend to look like a large asteroid. However, when the comets are visible from Earth they look like a bright spectrum or shooting star because of it's tail.
  • Comets get their tail because the melt and become ice and dust as they approach the sun.

  • This comet is referred to as Rosetta's target, or Rosetta's Comet 67P.
  • This picture was taken, using NASA's latest software drone.
  • This drone's name is Rosetta, and its job is to observe Comet 67P(which is why the comet's name is Rosetta's Comet 67P).
  • Comet 67P was discovered on September 20, 1969.

Youtube Video

The YouTube Video below describes one of the most famous comets: Halley's Comet. It describes Halley's path, its orbit, and its plans for returning. The makers of this video are Kurdistan Planetarium: an Astronomy and Science channel. The main vocabulary word that you will see and know while watching this video is ellipse, which is the path that a comet takes when it orbits around a planet.

  • Asteroids are airless, rock that are the remains from the formation of the solar system.
  • Since these rocks are the remains, they are very small and sometimes considered Dwarf Planets.
  • Though these asteroids are tiny, they orbit the sun and are still dangerous for anything in their path.
  • Near-Earth Asteroids are asteroids that have been nudged because of other planets gravitational force and those forces allows them to enter Earth.
  • One asteroid that had an affect on the world was when the Chelyabinsk Meteor hit Russia on February 15, 2013 due to a near-earth asteroid.

  • 253 Mathidle
  • 243 Ida
  • 433 Eros
  • 951 Gaspra
  • 2867 Steins
  • 25143 Itokawa
-just a few of many asteroids that roam space.

News Article Involving an Asteroid

This article is explaining all of NASA's latest projects. For an example, you will read about NASA wanting to take it a step further and capture near-earth asteroids. They plan to create a robotic spacecraft and they have a set time frame they are working in; its all a matter of getting the job done. One vocabulary word that will get defined is near-earth objects, which are objects that are moved by the gravitational force of other planets that allow them to enter Earth.
