These three short online lessons discuss asteroids, comets and meteors.

This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work. 

This video explains how to find factors.

How to solve for the horizontal displacement when the projectile starts with a horizontal initial velocity. We also explain common mistakes people make when doing horizontally launched projectile problems.

Other objects in the solar system are discussed in this online textbook viz. asteroids, meteorites, comets and dwarf planets.
