Select the correct text in the passage.
An astronomer has discovered an object, and she wants to conduct research on it. She has written a description of the
object. Which piece of evidence in the description disqualifies the newly discovered object from being a planet?
The object orbits a red dwarf star. The object appears to have no moons of its own. Current images show that it is
spherical in shape and has a mass about one-tenth that of Earth. It has a fast orbital period, orbiting its star
every
77 Earth days. The object lies in a region with millions of asteroids, colliding with them almost constantly.
