A	B
comet	a small body of ice, rock, and cosmic dust loosely packed together that gives off gas and dust in the form of a tail as it passes close to the sun
meteoroid	a very small, rocky body that revolves around the sun

What is a small body containing ice rock or cosmic dust revolving around the sun giving off gas?

A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail.

What is a body made of ice and dust?

Picture a dirty snowball up to a mile in diameter – an orbiting celestial body made up of ice, gases, rock, dust, and organic compounds. That’s a comet.

Which small body is made of dust ice?

Comets
Comets are icy bodies of frozen gases, rocks and dust left over from the formation of the solar system about 4.6 billion years ago. They orbit the sun in highly elliptical orbits that can take hundreds of thousands of years to complete.

What is difference between comets and asteroids?

The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid.

What does asteroid mean in science?

asteroid, also called minor planet or planetoid, any of a host of small bodies, about 1,000 km (600 miles) or less in diameter, that orbit the Sun primarily between the orbits of Mars and Jupiter in a nearly flat ring called the asteroid belt.
