Meteoroids orbit around the Sun; different meteoroids travels at different speeds and in different orbits. Some meteoroids orbit together (called stream component); these are probably comet remnants). Other meteoroids are in sporadic (seemingly random) orbits.
The fastest meteoroids travel at roughly 26 miles per second (42 km per second) through space.
Spacecraft Damage from Meteoroid
Meteoroids have done minor damage to spacecraft, including the Hubble Space Telescope (HST). About 100 tiny craters and chipped areas have been found on the HST; they were caused by impacts with tiny meteoroids.
There are three main types of meteorites. The most abundant are stone meteorites which are primarily made up of silicate minerals such as olivine, pyroxene and feldspar. As their name implies, iron meteorites are mainly composed of iron but also contain a significant amount of nickel. The rarest of the three are the stony-iron meteorites. They are a mixture of stony and metallic materials.
