What is S-type asteroid?
An '''S-type asteroid''' is an [[asteroid]] that is mainly ''silicaceous'', or made of a lot of [[silicon]]. This is why it is called an ''S-type''. About 17% of all asteroids are this type of asteroid, meaning that they are the second most common after [[C-type asteroid]]s. S-type asteroids are the most common asteroid in the inner [[main belt]], but become very rare farther out in [[outer space|space]]. The biggest asteroid of this type is [[15 Eunomia]]. S-type asteroids are the most mineral dense asteroids. {{science-stub}} [[Category:Asteroids]]
