Why is Pluto not considered a full planet anymore?
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.

What are the dangers of Neptune?
Powerful storms With winds of 1,305 miles per hour (2,100 km per hour), Neptune has some of the most extreme weather in the solar system. These winds travel three times as faster as those on Jupiter, and nine times faster as winds clocked on Earth. Such winds drive powerful storms.
Is there life on Venus?
Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.
