Question

What are the three criteria defined by IAU for a fully sized planet​

Answer 1

Answer:

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one it “has not cleared its neighboring region of other objects.”

Answer 2

Hey mate !!

Here is ur Answer ⤵️

A “dwarf planet,” as defined by the IAU, is a celestial body in direct orbit of the Sun that is massive enough that its shape is controlled by gravitational forces rather than mechanical forces (and is thus ellipsoid in shape), but has not cleared its neighboring region of other objects.

So, the three criteria of the IAU for a full-sized planet are:

1 - It is in orbit around the Sun.

2 - It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).

3 - It has “cleared the neighborhood” around its orbit.

Hope it helps you ✌️
