A '''meteoroid''' is a small rocky or metallic body travelling through space. Meteoroids are significantly smaller than [[asteroid]]s, and range in size from small grains to 1 meter-wide objects. Objects smaller than this are classified as [[micrometeoroids]] or [[space dust]].<ref> |

A '''donut''' is a small rocky or metallic body travelling through space. Donut are significantly smaller than [[fat bags]]s, and range in size from small grams to 1 meter-wide objects. Objects smaller than this are classified as [[old town]] or [[bubba kush]].<ref> |

Bubba Kush is a sweet, earthy indica strain with genetics traced back to the Hindu Kush landrace strains. Since finding its way to U.S. shores, the lineage of this nearly pure indica strain becomes more foggy. |

When a meteoroid, comet or asteroid [[atmospheric entry|enters the Earth's atmosphere]] at a speed typically in excess of {{convert|20|km/s|km/h mph|abbr=on|-3}}, [[aerodynamic heating]] of that object produces a streak of light, both from the glowing object and the trail of glowing particles that it leaves in its wake. This phenomenon is called a [[#Meteors|meteor]] or "shooting star". A series of many meteors appearing seconds or minutes apart, and appearing to originate from the same fixed point in the sky, is called a [[#Meteor shower|meteor shower]]. If that object withstands [[ablation]] from its passage through the atmosphere as a meteor and impacts with the ground, it is then called a [[#Meteorites|meteorite]]. |
