Our solar system flies through space in the shape of a speeding bullet, according to data from NASA's two Voyager spacecraft.


The sun and its planets are known to streak through the void of space at approximately 62,000 miles (100,000 kilometers) an hour.

The system travels within a bubble of solar wind—made of charged particles from the sun—called the heliosphere.


The edge of this bubble collides with the Milky Way galaxy's magnetic field at a distance some 200 times farther from the sun than Earth is.


A research team led by Merav Opher at Virginia's George Mason University found that, just outside the solar system, this interstellar magnetic field is inclined at a 60-degree angle relative to the plane of the Milky Way.


The solar system takes on its streamlined shape as it strikes the magnetic field at this angle, Opher explained.


"The shape of the solar system, this bullet, is really shaped by what lies ahead of us—the interstellar magnetic field," Opher said.
