article imageSolar System Is "Bullet Shaped"

Solar system flies through the vast space in the shape of a speeding bullet.
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.
Thanks to Voyager data, Scientists were able to calculate how fast the Solar system moves in space. And they found that our Solar system moves at an incredible speed of 62,000 miles an hour. For comparison sake, the fastest bullet, probably the Winchester .223 Super Short Magnum, has a muzzle velocity of about 4000 feet per second or 2,700 mph (4400 km/h). Our Solar system travels many times that speed. The solar system travels within a bubble of solar wind that is generated from the charged particles from the sun called the heliosphere.
The edge of this bubble shown in the picture collides with the Milky Way galaxy’s magnetic field at a distance 200 times farther from the sun than Earth is. This magnetic field is inclined at a 60 degree angle relative to the plane of the Milky Way.
Merav Opher at Virginia’s George Mason University did this study and said that the Solar system takes its streamlined shapes as it strikes the magnetic field at this 60 degree angle.
"The shape of the solar system, this bullet, is really shaped by what lies ahead of us—the interstellar magnetic field," Opher said.
Opher and colleagues found this from the radio data they received from Voyager spacecraft which left the Earth in the 70s, the craft has just reached the solar system edge.
The solar system moves at an incredible speed yet we don't feel that movement, it is amazing how the whole thing works.
