Which of the following is NOT a criteria for a celestial object to be a planet? -The object has cleared the neighborhood around its orbit of smaller objects.

-The object is in orbit around the Sun.

-The object has a nearly spherical shape.

-The object must be massive enough have a gravitational pull on the sun.

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.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
