How old is the oldest meteorites?

Answer 1

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.

Answer 2

We 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.

Answer 3

A 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.

Answer 4

it 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.

Answer 5

Any "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.

Answer 6

The oldest meteorites are estimated to be around 4.6 billion years old, dating back to the early formation of our solar system. These meteorites provide valuable insights into the origins of our solar system and the processes that occurred during its early stages.

Answer 7

Any given meteor is less than a few seconds old.

Answer 8

Well if it is part of our solar system 4.8 Billion years old as everything in our solar system is thought to be the same age.

Answer 9

36 trillion years old
