Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.(MUSIC) JOAN CARTAN-HANSEN, HOST: Asteroids are among the most ancient objects in the solar system.
A lot are found in the asteroid belt.
This is the area of our solar system just between Mars and Jupiter.
Scientists think there are between one point one and one point nine million asteroids floating around here.
The biggest asteroid in the asteroid belt is Vesta.
It's 329 miles or 530 kilometers in diameter.
Asteroids are divided into three types based on their composition.
M-types asteroids are metallic, made of nickel and iron.
S-type asteroids are made of rocky materials, nickel, and iron.
And C-class asteroids are made of clay and silicate rock.
They're dark in color and are the most common type of asteroid.
Asteroids generally stay within the belt, but occasionally one gets pulled out by Jupiter's gravity.
It can head into the inner solar system, sometimes toward Earth.
NASA has ways to protect the Earth from large asteroids or comet strikes.
But smaller bits of solar body debris hit often.
We see them as shooting stars.
For more information about asteroids and comets, check out the Science Trek website.
