Researchers from The Open University and the University of Central Lancashire in the U.K., have found a ring of dust following the orbit of Venus.
Using data from the STEREO (Solar Terrestrial Relations Observatory) spacecraft, researchers found the ring dust trailing behind the second planet for about 137 million miles (220 million kilometers).
The ring is similar to the one found about 20 years ago trailing our own planet. The dust is part of the zodiacal dust that permeates the Solar system.
As the name implies, the dust is responsible for the zodiacal light that you can catch at sunset and sunrise.
The dust is not relevant to planetary formation, because it is only about 100,000 years old. However, the ring is very important in understanding what happens to interplanetary dust, which forms from asteroid collisions and cometary dust.
