Question

what are the four qualifications any celestial body should have to become a planet​

Answer 1

Answer:

1. A planet is a celestial body that is in orbit around the Sun

2. Has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape .

3.  Has cleared the neighbourhood around its orbit .

Explanation:

In its declaration the IAU defined a planet as an object which 1) orbits the Sun, 2) is massive enough to be in hydrostatic equilibrium (basically that means it's round), and 3) has cleared the neighborhood around its orbit .

So far scientists have categorized exoplanets into the following types: Gas giant, Neptunian, super-Earth and terrestrial .

Hope it was helpful .
