5 billion years ago
it was actually form 4.6 billion years ago When The Big Bang Happened
approx. 5 billion years
4.6 billion years ago or 5 billion years if you round up. :)
correct answer 26,000 A+
But ... there are many bodies in our Solar system that have no atmosphere.
The best guess is that our solar system is about 8 billion years old.
Our solar system is thought by astronomers to be about four and a half billion years old.
It takes a quarter of a billion years for the solar system to circle the milky way
About 1,000,000,000,000,000,000,000,000,000,000,00 years ago.
Since the Solar System is thought to be about four and a half billion years old, and the galactic year calculated to be around 250 million years, the Solar System's age in terms of galactic or cosmic years would be roughly eighteen.

The solar system takes approximately 230 million years to orbit the center of the Milky Way.
Depending entirely on the boundaries of the Solar System, it has been estimated to be a bout 2 light years.
Between about 4 and 4.5 billion years ago the solar system was rather chaotic. There were many more asteroids and planetoids with unstable orbits. As a result collisions were much more common in the early solar system. Since then most objects with unstable orbits either collided with planets and moons or with the sun or were ejected from the solar system.
This is estimated at about 200 million years.
It takes about 225 million years for the solar system to travel once around the Galaxy. Th solar system is about 4.6 thousand million years old. So a rough estimate would be 20 times.
