Pluto is now classified as a dwarf planet because, while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighborhood surrounding its orbit.
How did Pluto planet destroyed?
In his novel World of Ptavvs (1966), it is theorized to have been a moon of Neptune knocked out of orbit by an interstellar craft moving near the speed of light. A fusion-driven spacecraft landing on Pluto in this story releases the frozen methane, oxygen, etc., and causes the entire planet to be engulfed in flames.

What planet has 16 hours in a day?

What is the hottest planet?

Which is the smallest planet?

How long would it take to get to Pluto?
