Question

1. why was pluto reclassified as a dwarf planet? pluto is in direct orbit with the sun. pluto has not attained hydrostatic equilibrium. plutos orbit is not on a plane with the planets. pluto has not cleared its neighboring region of other objects.

Explanation:

The International Astronomical Union (IAU) defines a planet as an object that: 1) orbits the Sun directly, 2) has hydrostatic equilibrium (rounded shape), and 3) has cleared its orbital neighborhood of other debris. Pluto fails the third criterion—it shares its region (the Kuiper Belt) with many other objects, so it was reclassified as a dwarf planet.

Answer:

Pluto has not cleared its neighboring region of other objects.
