An Overview of Pluto

Pluto - Planets In Our Solar System (an overview of Pluto)Pluto is the last planet of the Solar System according to what most scientists say, considering its distance from the Sun. There are also some other scientists who do not count Pluto as a planet of our solar system because they consider it a dwarf planet. It is also because it falls in the Kuiper belt that has a ring of bodies before Neptune.


When it comes to its dimensions, It is the largest and the second massive dwarf planet in the solar system while it is obviously the ninth largest and the tenth most massive known object which actually orbits the Sun directly. Since it is also a Neptunian object, here it qualifies for being the largest by volume while it is less massive than Eris there.

Pluto has a volume of 0.00647 Earth’s and it has a mass equivalent to 0.00218 Earth’s. The surface gravity, however, is 0.620 meters per second squared.


Pluto has five moons namely Charon, Styx, Nix, Kerberos, and Hydra and the Lowell Observatory had discovered this planet through Newtonian mechanics which is why they had the right to name this planet. Thousands of suggestions were received but then Venetia Burney who was just an 11-year-old interested in classical mythology who actually gave the name Pluto after the Gods of the underworld.


Pluto has lots of nitrogen, methane, and carbon monoxide and has a tenuous atmosphere of ice all around. It also has a surface pressure of just 1 Pascal which is 100,000 times less than that of the Earth. This particular planet has a lot of mountains as well as pressure waves that have given resulting 20 regularly spaced haze layers on it. It has a surface temperature which is very cold than the expected 70K.
