According to the International Astronomical Union, which of the following is one of the criteria for an object to
classified as a Planet? Select all that apply.
the object must orbit the Earth
the object must be in orbit with objects that are larger in size and mass
the object must be large enough for gravity to shape it into a round ball
the object must have at least two moons

It's def not A, and I don't believe D is true. I'm not sure if both B and C are correct, but since it's all that apply I'm going to say they are. Sorry, I'm never very good with astrology, you may want someone to double check me!

Answer:

For an object to be specified as a planet, it must be large enough for gravity to shape it into a round ball.

Explanation:

Following are the criteria specified by the "International Astronomical Union" for an object to be recognized as a planet:

The object must "orbit a star".

It must have sufficient mass to achieve hydrostatic equilibrium, which in association with gravity gives the object a roughly spherical shape.

It must be the biggest and the heaviest object in its orbit capable enough of keeping the orbit clear for its own motion.
