They are probably fragments

The model also showed that some

Over millions
of years, these planets become shrouded by orbiting debris generated from the collision
of comets,
asteroids, and
other objects.
Many scientists believe the extinction was caused by an
asteroid impact; some think regional volcanism was to blame, and
others suspect it was due to a combination
of the two.
However, unlike
other asteroids, they sometimes have the appearance
of comets, when dust or gas is ejected from their surfaces to create a sporadic tail effect.
Other theories involve planetary collisions that knock worlds off course or simply a large mass
of materiallike an
asteroid that jumps aboard and, by its mass and impact, tilts the once - flat orbit.
This suggests that the way our planets and
