Question

A celestial object takes six to seven years to revolve once around the Sun. It’s made mostly of ice, some of which vaporizes when it passes near the Sun. What is this object?

1) an asteroid
2) a comet
3) a meteorite
4) a planet

Answer 1

A comet. It’s a smaller celestial body that’s composed of mainly ice and dust.

Answer 2

The answer is 2) a comet

Step-by-step explanation:

Comets are celestial bodies made up of ice, dust and rocks that revolve around the Sun. They are made of ice, such as water, carbon dioxide, ammonia and methane, mixed with dust. A comet heats up as it approaches the sun, whose heat causes the ice in the core to become gas; The pressure of sunlight and high-speed solar particles blow the comet's materials away from the sun, forming a long and sometimes bright tail.
