Answer:
The option which is not a criteria for a celestial object to be a planet is;
The object must be massive enough have a gravitational pull on the Sun
Explanation:
There are three criteria for a celestial object to be classified as a planet including;
1) The object's orbit is around the Sun
2) The shape of the object is nearly round due to its mass which is capable of assuming hydrostatic equilibrium
3) Other smaller objects in the neighborhood around the object has been cleared by the object
Therefore, the option which is not a criteria for a celestial object to be a planet is that it must be massive enough to have a gravitational pull on the Sun as every two objects in the Universe share a common gravitational pull according to Newton's Law of Gravitation.
