Why do asteroids and comets differ in composition group of answer choices?
Why do asteroids and comets differ in composition? Asteroids formed inside the frost line, while comets formed outside. When do comets generally begin to form a tail? Where are the Trojan asteroids located?
Why do asteroids differ in composition?
Why do asteroids and comets differ in composition? a) Asteroids and comets are both made of rocky and icy material, but asteroids are larger in size than comets. b) Asteroids are made mostly of icy material. Comets are made of mostly rocky material.
How do you determine the composition of an asteroid?
There are many ways to tell what asteroids are made of. One way is to send a spacecraft there, for example NASA’s NEAR spacecraft that orbited Eros for a year. While in orbit, the spacecraft used an infrared camera and spectrometer and an x-ray/gamma ray spectrometer to look at the composition of the asteroid.
What is the composition of the asteroid?
Asteroids are made mostly of rock — with some composed of clay and silicate — and different metals, mostly nickel and iron. But other materials have been found in asteroids, as well.
What are the different types of asteroid?
The three broad composition classes of asteroids are C-, S-, and M-types.
- The C-type (chondrite) asteroids are most common, probably consist of clay and silicate rocks, and are dark in appearance.
- The S-types (“stony”) are made up of silicate materials and nickel-iron.
- The M-types are metallic (nickel-iron).
What are the characteristic of asteroid?
Asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across. In total, the mass of all the asteroids is less than that of Earth’s moon.
What term best describes a small asteroid?
Traditionally, small bodies orbiting the Sun were classified as comets, asteroids, or meteoroids, with anything smaller than one meter across being called a meteoroid. The three largest objects in the asteroid belt, Ceres, Pallas, and Vesta, grew to the stage of protoplanets.
What exactly is an asteroid?
Definition: Asteroids are actually minor planets which can neither be classified either as a planet or as a comet. These are generally in the direct orbit around the Sun, also known as the inner solar system. The larger forms of asteroids are also known as planetoids.
What asteroid will hit Earth?
