1405: "Meteor"

No, only LAVA is called 'magma' while underground. Any other object underground is called 'lava'.

So do we call anything magma while underground? I think this comic may make some people more annoying.

Doesn't the existence of Widmanstätten pattern in a piece of meteorite (that too, isn't it a meteorite once it enters the atmosphere??) mean it was never molten on the planet?

In defense of inaccurate terminology, "Enter Village Flees From Magma" makes for a much more intriguing headline.

It's a meteor only while it's in the process of falling to Earth.

One it hits the ground, it's a meteorite.

While it's still just floating around in outer space, it's a meteoroid.

Think of it this way: a meteor is the defining object, a "shooting star". Meteorite is, like other -ites, a substance, namely the stuff that meteors are made of; and by extension, a meteorite is a rock made of that stuff. And a meteoroid is a meteor-like object, in the same way that humanoid is human-like and a toroid is torus-like; it's something that could be a meteor, if it happened to fall to Earth, and is in many sense just like a meteor, except in that it's not falling to Earth.

A "meteor" isn't actually a rock, it's the trail of light made by entering the atmosphere. Whether the rock is in space or falling to Earth it is a "meteoroid", changing to a "meteorite" once it hits the ground.

To be even more pedantic: A meteor is technically the light-trail you observe when a meteorite is in the process of falling to earth. So a meteor is not an object at all, it's a process / phenomenon.

So, to recap:
Meteor: The light-trail you observe when a meteorite falls to earth
Meteorite: A rock that has fallen from space to earth
Meteoroid: A (small) rock floating in outer space
Asteroid: A bigger rock floating around in outer space
Planetoid: An even bigger rock floating around in outer space, generally used as a synonym for dwarf planet
Comet: An icy rock floating around in outer space, in an orbit such that it heats up and produces a tail during its close approach to the sun.
Meteorology: The study of meteors*.

If I understand correctly, it's once you hit a hole in the ground (become buried).

Isn't it a marvel there were all these holes there to catch the meteorites? They must attract them. We should fill all the holes to prevent an extinction level event.

Huh. After watching an episode of Nova on asteroids recently, I had been under the impression that pretty much all of the rocks floating around in space were classified as ASTEROIDS. (Though, I might have misunderstood, or they may have failed to categorize smaller rocks that aren't all that exciting when they hit Earth's atmosphere).

The asteroids are a specific set of astral bodies, namely the ones in the band between the orbits of Mars and Jupiter (the Asteroid Belt), not a specific kind of astral body. An asteroid, if somehow nudged in the direction of Earth, could be come a meteor, but not everything that could become a meteor is an asteroid.

Pfhorrest wrote:An asteroid, if somehow nudged in the direction of Earth, could be come a meteor, but not everything that could become a meteor is an asteroid.
So... a meteorite may have once been an asteroid. But when did it become a meteorid? Surely before it formed the meteor, perhaps when it was nudged into its fatal orbit, or maybe when it was on a path to be nudged into this fatal orbit... or maybe it always was a meteorid (with a long time to go before it proved itself). Thus, there would be this well defined class of objects (that will eventually hit the earth) which cannot easily be enumerated (without waiting for it) that are called meteorids.

That's the most common usage, for sure. However, asteroid is currently undefined by the IAU, so there is a bit of leeway in how it's used— even for pedants! :) The Greeks and Trojans (ie, the small bodies in the Sun-Jupiter lagrange points) are often called asteroids too, for example.

The term was originally coined because they appeared star-like— that is, they were so small that they appeared as points rather than discs even through a telescope.

Considering the root, aster, I"d be inclined to define an asteroid as a body too irregular/small to quialify as a planet[oid] resolvable (telescopically or not) from Earth with a meteor[edit: oid] being too small for that.
