The comets

Children's Educational Center of Oradea, Romania

Comets are icy remnants from our solar system formation. These are objects fainter but when they pass near the Sun are spectacular celestial bodies, due the particles that form the comet tail and coma.
We have built a comet with Astronomy and Space Science Club's members of Oradea. Snow, sand and a flashlight in order to view comet tail. It was visible near the Sun with and her tail were opposite the Sun.
