Comets contain ice.
Comets are made up of dust, rock, ice, and frozen gases. The most common compounds found in comets include water ice (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), and carbon monoxide (CO). Additionally, comets can contain organic molecules such as formaldehyde and methanol.
Yes, comets contain more ice than metals and gases.
Comets come from the coldest parts of the universe and contain ice and organic materials. Scientists believe that impacts from comets on earth are responsible for contributing to organic materials and possibly life on earth.
A star, 8 planets, lots of satellites, minor planets, comets, asteroids, random rocks, & lots of dust.
Comets and asteroids are both celestial bodies orbiting the Sun. Comets are icy bodies that develop a tail when passing close to the Sun, while asteroids are rocky or metallic objects that typically orbit in the asteroid belt between Mars and Jupiter. Both comets and asteroids can occasionally enter Earth's vicinity.
They are often referred to as 'dirty ice balls.' So I would say that they are mostly made of water and contain only a little bit of dirt.
Comets, though they may contain other elements.
No. While comets contain some rock, they are mostly made of ice.
