How long has earth been in the solar system?

The earth - and the other seven planets, comets, asteroids and minor planets - are all "charter members". They've been in the solar system since it evolved out of the accretion disc around the proto-sun about 4.5 to 5 billion years ago.

What is the approximate number of years that a meteor will travel to earth?

Meteorites have generally been around since the formation of the Solar System, over 4 billion years ago, until they happen to collide with Earth.


Why meteorites provide windows to the earth's past?

Meteorites are "space rocks" which have fallen to earth. Because these bodies have been in space for billions of years, likely since the formation of our solar system, they have not been subject to any type of weathering, erosion, or other degradation that happens here on earth. So, they're "pristine" examples of what things were like in our solar system 4+ billion years ago.
