Most probably originated around the time of the creation of the solar system; about 4.5 billion years ago; some may be from outside the solar system and may be considerably older than that.
But note that meteorites have been striking the Earth ever since they were formed, so some have hit the Earth recently.

∙ 10y agoWe can't be certain, but most astronomers believe that the average "space rock" formed about the same time the solar system itself did, about 4.6 billion years ago. Of course, all the matter that formed our solar system existed before then, in previous stars and star systems, so it could be MUCH older. And likely a lot of it is stuff that was part of the "proto-Earth" before it collided with another planet perhaps the size of Mars, which re-made the Earth and created the Moon.
And some of the space rocks were formed only relatively "recently", from the collision of asteroids in the asteroid belt, or in some cases, being blasted off of the surface of Mars my some titanic impact eons ago.
Of course, the space rocks didn't actually become "meteorites" until they hit the Earth, so some of them were formed just last week.

∙ 12y agoA meteoroid is a small piece of debris in the solar system, a meteorite is a meteoroid that has landed on Earth. A meteor is a meteoroid that has entered Earths atmosphere.
So a meteor is only about 1 to 10 seconds old.

∙ 12y agoit depends on the rock color..........if its a red rock then it will live for 1 year, if its a blue rock then it will live forever, if its any other color then the blue rocks and the red rocks jump the rest of the rocks and that's how explosions are made.

∙ 12y agoAny "needle of light" you see streak across the night sky (a "shooting star", by definition a meteor) is a leftover piece of space grit or dust that goes back to the formation of our solar system. In other words, a meteor is about 4.5 billion years old.

The age of the solar system can be established by radioactive dating of?
the oldest meteorites.
The oldest objects in the solar system whose age has been measured are?
meteorites
Which country has the most meteorites?
Oman has 2.412 meteorites.
Where do meteorites occur?
Meteorites occur all over the world
Who was the oldest man into space?
the oldest man who went to space was 77years old
How old is the the earth and how did scientist know?
About 4.5 billion years old - calculated by the radioactive dating of the oldest rocks found AND the dating of even older meteorites.
How do scientists find out how old meteorites are?
If meteorites formed from dust from the early universe, then we would expect them to be very old. Indeed, this is what we find. Scientists have used radiometric dating to measure the ages of meteorites. The results show ages of around 4,500,000,000 years that's seven hundred million years older than the oldest rocks on Earth.

Who are the oldest old?
the oldest are old bcause they are old

the oldest map is about 375years old!
What are the kinds of meteorites?
Iron meteorites, stony meteorites and stony-iron meteorites.

Stony meteorites, iron meteorites, stony-iron meteorites.
What are the three major types of Meteorites?
Stony meteorites, iron meteorites, stony-iron meteorites.
How old is the oldest flute?
The oldest Flute is 35000 years old.
How old is the oldest guineapig?
the oldest guinea pig is 10 years old.
What evidence supports the hypothesis that Earth is 4.6 billion years?
Among other things, rocks have been found that are over 4 billion years old. The age of such rocks is determined by radioactive dating. Note that this is not "a" method, but perhaps 40 different methods (depending on the isotopes involved), which complement one another.The exact age of the Earth is harder to determine exactly; but basically, it must be at least as old as the oldest rocks found.
