The rings trace the orbits of planets, whose gravity tugs dust into place around the Sun, as it drifts by on its way to the center of the solar system.
Dust is dispersed throughout the entire solar system, but it collects at grainy rings overlying the orbits of Earth and Venus, rings that can be seen with telescopes on Earth.
(NASA's Goddard Space Flight Center/Mary Pat Hrybyk-Keith) Another ring around the Sun Guillermo Stenborg and Russell Howard, both solar scientists at the Naval Research Laboratory in Washington, D.C., did not set out to find a dust ring.
Asteroids hiding in Venus’ orbit This isn't the first time scientists have found a dust ring in the inner solar system.
Since then, scientists determined the dust ring in Earth's orbit comes largely from the asteroid belt, the vast, doughnut-shaped region between Mars and Jupiter where most of the solar system's asteroids live.
