Question

Why Pluto left the solar system? What is the mass of Pluto?​

Answer 1

Step-by-step explanation:

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

Pluto left the solar system because it was reclassified as a dwarf planet by the International Astronomical Union in 2006 due to its size and mass. Pluto's mass is estimated to be around 0.00218 Earth masses, or 1.30 x 10^22 kg.
