How are asteroids and comets similar
Asteroids and comets are both small, rocky, and icy bodies that orbit the sun. However, they differ in their composition, appearance, and origin. Asteroids are primarily composed of rock and metal, while comets are primarily composed of ice, dust, and rock. Comets often have a visible coma or tail when they come close to the sun, due to the melting of their icy surface. In contrast, asteroids do not melt and do not develop comas or tails.
Both asteroids and comets can pose a threat to Earth if they collide with our planet, but the likelihood and severity of the impact depend on their size, speed, and trajectory. Scientists study these objects to better understand their properties and potential hazards.
To determine which of the following objects are made of ice and dust, we need to understand their definitions.
Asteroids: These are rocky objects made mainly of metal and other solid materials, usually found in the asteroid belt between Mars and Jupiter. They are generally composed of rock and metal, not ice and dust.
Comets: Comets are small celestial bodies made up of a mixture of ice particles, dust, rocky debris, and organic compounds. The nucleus of a comet is primarily composed of ice and dust, which evaporates when the comet gets closer to the Sun, creating a glowing coma (a cloud of gas and dust) and a tail.
Meteor: A meteor refers to the bright streak of light produced when a small, solid particle (meteoroid) from space enters the Earth's atmosphere and burns up due to friction. A meteor does not consist of ice and dust but is instead a solid object.
Meteorites: A meteorite is a meteoroid that survives its passage through Earth's atmosphere and lands on the Earth's surface. Like meteors, meteorites are composed of solid material and are not made of ice and dust.
Based on the definitions provided, the correct answer is B. Comets, as they are known to be made of ice and dust.
