Where is the main asteroid belt located quizlet?
Where is the asteroid belt located? The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets.
What do asteroids and comets have in common?
Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds.
Where is the asteroid belt located and why?

How do we know what asteroids are made of quizlet?
How do we know what asteroids are made of? Astronomers have studied meteorites that originated in the asteroid belt. The spectrum of sunlight reflected from an asteroid shows absorption features, from which we can determine its composition.
How do we know what asteroids are made of?
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 evidence for the existence of the Oort cloud?
Answer: There is what one could call “indirect observational evidence for the Oort Cloud. It has been known since 1932 (first proposed by Ernst Opik, then updated by Jan Oort in 1950) that one needs a source for long-period comets that is beyond the orbit of Pluto.
Where are most asteroids found?
Kid-Friendly Asteroids Although asteroids orbit the Sun like planets, they are much smaller than planets. There are lots of asteroids in our solar system. Most of them live in the main asteroid belt—a region between the orbits of Mars and Jupiter. Some asteroids go in front of and behind Jupiter.
Can we stop a asteroid?
No attempts are made to stop the asteroid, however, people desperately search for bunkers to hide in before the comet strikes.
