Today, 3B learned about Comets, what they're made of, and how they're formed. We first watched a short movie about comets (provided below) then made our own comet.

Quick Comet Facts

  • No two comets are alike. They differ in size, shape, and what they’re made of.

  • Comet tails are a result of solar wind. Energy and particles from the sun push on the comet. This force pushes dust and gas behind the comet. The ion dust and gas have different weights, so they separate, making two specular tails.

  • Once scientists saw a third tail, which was a smaller tail forming just between the dust and gas tail. They discovered it was made of salt.

  • Comet tails have been discovered to be so long that Voyager 2 passed through one that was thousands of miles away!
