is a small piece of dust, rock, ice or metal moving through space. They range in size from a speck of dust but are smaller than an asteroid.
Small bodies in orbit about the Sun which may fall to Earth or to another planet. More about meteoroids...
dust and debris that travel through space and become meteors when they enter Earth's atmosphere.
(meet' ee a royd) - Any rock or iron natural object moving through interplanetary space that is smaller than an asteroid and larger than a molecule.
A tiny grain of silicate or metal between 1 and 10 millimeters across that orbits the Sun. Sometimes meteoroids fall into Earth's atmosphere and become meteors.
A solid body in orbit about the Sun, much smaller than an asteroid and usually weighing less than about 100 kilograms.
Solid particle or body of small dimensions in extraterrestrial space.
A rocky or metallic object of extraterrestrial origin that is smaller than an asteroid that would become a meteor if it entered the Earth’s atmosphere.
A piece of comet debris. When the Earth enters a meteoroid stream left by a comet it produces a meteor shower.
A particle of iron or rock found in inter-planetary space. Distinguished from planets or asteroids by its much smaller size.
An chunk of rock from space that is smaller than an asteroid.
Chunk of interplanetary debris prior to encountering Earth's atmosphere.
A small piece of cometary or asteroidal debris in orbit around the Sun. The meteoroid becomes a "meteor" as it enters our atmosphere and becomes a "meteorite" if it reaches the Earth. The difference are both semantic and physical, since all three terms designate different stages of life of the same object.
A small body moving through space, or revolving about the sun, which would break up and be seen as a meteor on entering the Earth's atmosphere.
A small, rocky object left over from the formation of the Solar System moving through interplanetary space. A meteoroid produces a meteor when it enters the Earth's atmosphere.
A small piece of interplanetary debris, particularly one on a collision course with the Earth. When such an object passes through the atmosphere and vaporizes, it produces a meteor.
a meteor before it enters earth's atmosphere a meteor from another galaxy a meteor that causes a great deal of destruction
a meteorite before it hits the surface of the Earth
a natural object floating in space
an interplanetary chunk of matter smaller than a kilometer and frequently millimeters in size
an object in space that may, if it enters our atmosphere, become a meteor
a particle or rock traveling through space
a pebble or stone in space
a piece of debris (asteroid or comet debris) traveling through space towards our planet
a piece of interplanetary matter that is smaller than a kilometer and frequently only millimeters in size
a piece of stony or metallic debris which travels in outer space
a piece of stony or metallic material that travels in space
a solid body orbiting the sun
a solid object less than one kilometre in diameter that is in orbit around the Sun and that, under the right circumstances, could possibly hit the Earth
a tiny ball of dust from tails of comets that ventures through space
A small (1 km) natural object whose orbit around the sun may cause it to collide with other planetary bodies. The term meteoroid is usually used to describe the rocky core of a meteor, while the term meteorite is used to describe the object once it is on the ground.
An asteroid on a collision course with Earth
A fragment of matter which may turn into a meteor if it enters Earth's atmosphere or a meteorite if it strikes Earth.
the term that collectively describes all forms of meteoric material, including meteors and meteorites.
Solid object moving in interplanetary space of a size smaller than an asteroid and larger than a molecule.
A small, solid body moving through space in orbit around the Sun.
One of a large number of celestial bodies of various size that appear as meteors when they enter Earth's atmosphere.
These are small objects which are believed mainly to come from asteroids and comets. They come in two main types, stony and iron, with some intermediate. Sometimes a meteoroid will cause a flash in the night sky as it burns up on entry, these are known as meteors. Showers of meteors are often associated with comets since they often occur as the earth passes across the orbit of a comet. If a meteoroid hits the earth, it is known as a meteorite.
a piece of comet or asteroid debris from space that can burn up in Earth's atmosphere to produce a meteor
a solid object traveling through space at high speed.
a rocky or icy fragment that travels through space
Debris from an asteroid or comet in space.
Bits of dust and pieces of rock and metal in space. Some of them fall through the Earth's air and burn up. And when they do, we call them Meteors.
Tiny sand, or rock sized fragments of cometary debris in our Solar System. When one hits the Earth's atmosphere, it burns up and partially or completely vaporises leaving a trail of glowing vapour known as a shooting star, or meteor. If part of the meteor / meteoroid hits the ground, it is called a meteorite.
a small rock that orbits the sun
An object in space; similar to but smaller than an asteroid
Meteoroids are tiny stones or pieces of metal that travel through space.
a small rocky object orbiting the Sun; smaller than an asteroid
A particle or chunk of typically rocky or metallic material in space before any encounter with the Earth.
Any solid object moving in interplanetary space that is smaller than a planet or asteroid but larger than a molecule.
Fragments of material which vaporize when they have a close encounter with a space body which has an atmosphere.
A solid object moving in interplanetary space, much smaller than an asteroid but much larger than an atom or molecule.
A solid object moving through interplanetary space of a size considerably smaller than an asteroid and considerably larger than an atom or molecule. When the object glows while traveling through the Earth's atmosphere, it is called a meteor; when it reaches the surface of the Earth, it is called a meteorite.
A small solid body moving through interplanetary space; after falling to Earth it is called a meteorite.
Any of the small solid extraterrestrial bodies that hits the earth's atmosphere.
A solid object moving in interplanetary space, of a size considerably smaller than a asteroid and considerably larger than an atom or molecule. See also: Fireball, Meteor, Meteorite, Meteoroid Stream
a natural small solid object in an independent orbit in the Solar System.
On average, a meter-sized boulder that has probably escaped from the asteroid belt and thus roams through the Solar System, perhaps hitting the Earth's atmosphere, thus causing meteor showers.
A piece of rock or dust in space with the potential to enter Earth's atmosphere and become a meteor or meteorite.
It is a piece of fast moving debris e.g. dust or fragment of rock that has not entered the Earth's atmosphere but has the potential to do so.
A meteoroid is a relatively small (sand- to boulder-sized) fragment of debris in the Solar System. When entering a planet's atmosphere, the meteoroid is heated up by ram pressure and partially or completely vaporizes. The gas along the path of the meteoroid becomes ionized and glows.
