Tiny grains of minerals smaller than the width of human hair hold clues to the construction of our planet Earth.
The spiral arms orbit at 210 kilometers per second, whileis speeding along at 240km per second, meaning our solar system is surfing into and out of the galaxy's arms. You can think of the spiral arms as dense regions that slow the passage of stars much like a traffic jam, which only clears further down the road .
This model results in approximately 200 million years between each entry our solar system makes into a spiral arm of the galaxy. Milky Way’s structure and Solar System’s orbit through it may be important in controlling the frequency of some large impacts on Earth, which in turn may have seeded crust production on the early Earth.
