Two new discoveries may be revealing new information about the inner solar system.
A new study reveals that the planet mMercury, which is the closest planet to the sun, shares its orbit with a big ring of wandering dust.
Not only that, but a second study says a similar ring exists near Venus, which orbits between Mercury and Earth.
Researchers believe a cloud of as-yet-undiscovered asteroids may be responsible for the dust ring near Venus.
As for Mercury, it was long believed the planet was too small and too close to the sun to have a dust ring.
But researchers believe such a ring exists, and it’s likely more than nine million miles wide.
