Why is Pluto a dwarf planet? And for what reason it has become vanished?
No, pluto did not disappear As described by the IAU, a 'dwarf planet' is a celestial body in direct Sun orbit that is large enough to influence its form through gravitational forces rather than mechanical forces (and is, therefore, ellipsoid in shape) but has not cleared other objects from its neighboring area.
So, the three criteria of the IAU for a full-sized planet are:
- It is in orbit around the Sun.
- It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
- It has "cleared the neighborhood" around its orbit.
Pluto meets only two of these criteria, losing out on the third. In all the billions of years it has lived there, it has not managed to clear its neighborhood
