Asteroids

An asteroid is a small, rocky object that orbits the Sun. Most asteroids are found in the asteroid belt, a region of space between the orbits of Mars and Jupiter. They are remnants from the early formation of the solar system, and studying them can provide valuable insights into the history of our solar system.

Characteristics of Asteroids

Asteroids come in various shapes and sizes, ranging from a few meters to hundreds of kilometers in diameter. They are primarily composed of rock and metal, and some may also contain water and organic compounds. Their irregular shapes and lack of atmosphere distinguish them from planets.

Formation and Composition

Asteroids are believed to be remnants of the early solar system, left over from the process of planetary formation. They are composed of materials similar to those found in the inner planets, such as silicate rock and metals like iron and nickel. Some asteroids may also contain valuable resources, such as precious metals and rare earth elements.

Impact on Earth

Occasionally, asteroids can collide with Earth, causing significant damage. The study of asteroids is important for understanding and mitigating the potential risks associated with asteroid impacts. Scientists are actively researching ways to track and potentially deflect or destroy any asteroids on a collision course with Earth.

Study Guide

To better understand the topic of asteroids, consider the following study guide:

Research the history of asteroid discovery and the methods used to detect and track asteroids.
Learn about the composition and physical characteristics of different types of asteroids.
Explore the potential impact of asteroid collisions on Earth and the efforts to monitor and mitigate such risks.
Investigate the potential for asteroid mining and the resources that could be extracted from asteroids.
Consider the future exploration of asteroids, including potential missions to study and even mine asteroids.

By studying asteroids, you can gain a deeper understanding of the solar system's formation and evolution, as well as the potential impact of asteroids on Earth and the opportunities they present for future exploration and resource extraction.

PHYSICAL SCIENCE (NGSS)

Matter and Its Interactions

Students who demonstrate understanding can:

Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.

Energy

Students who demonstrate understanding can:

Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
