Why Is Pluto So Cold

Pluto is unlike the other planets in that it has an icy surface instead of a rocky surface, like the inner 4 (terrestrial) planets, or a deep atmosphere, like the next 4 (gas giant) planets.

Pluto isn’t a planet for many reasons the main one being, it only follows two of the three criteria of being a planet. According to the article “Pluto: Planet or not?”, for Pluto to be a planet it needs to meet three pieces of criteria. In the article “Pluto: Planet or not?” it states that “Pluto meets two of these three criteria.” Therefore, Pluto should not be considered a planet because, it doesn't meet the criteria it needs to. Many scientist would agree that Pluto is considered a dwarf planet. “Pluto is a dwarf planet” Christensen wrote. It’s just plain and simple, Pluto is a dwarf planet, no doubt about it. There shouldn’t be any confusion about whether Pluto should be considered or not for many reasons. If it doesn’t meet all three

Astronomers now label Pluto as a “dwarf planet” because it does not meet all of the criteria to be a planet. It is also not alone in its orbit; it is part of a wide group of small-scale objects that have been detected revolving around the Sun beyond Neptune.

Pluto has such an erratic orbit that it crosses into Neptune orbit, which is extremely dangerous (science.howstuffworks 1). Although very unlikely to happen Pluto and Neptune could essentially run into each other with a possible explosion, eliminating one of our eight planets. If all the planets in our solar system orbit in the same direction than why should Pluto be included when it has an entirely different

My Thesis statement is Phuto was once considered to be a planet but now Pluto is the most famous dwarf planet in our solar system. Pluto is made up of ⅔ of rock and ⅓ of ice. Pluto was discovered by Clyde Tombaugh on January 23, 1930. Pluto is very very cold you can't even imagine how much colder it is than Antarctic.If that happen in Earth the air would turn into snow that's how cold it would be about 230 degrees below zero Celsius. When you want to see Pluto up in the sky you can't even see Pluto with your naked eye. Pluto is very hard to see once you look in the telescope it look a little like a star even with the telescope.

As mentioned earlier, Pluto has a rather unusual orbit. Pluto, while it is the furthest planet from the sun, for twenty years during its two-hundred and forty nine year orbit, it is actually the eighth planet, crossing over Neptune’s orbit. Regardless of the fact that the orbits of the two planets cross, their orbits will not allow for them to ever collide. This is mainly due to Pluto’s orbiting not staying in the elliptic plane. Because of its unusual orbit, Pluto travels above and below Neptune as the cross, avoiding collision. What also allows these two bodies to cross paths and avoid impact is that when Pluto is at one side of the sun, Neptune is at the other. This is a result of Pluto taking three times as long to make one orbit around the sun in comparison to Neptune.

The discussion about Pluto’s status in our solar system is still in question. The definition of a planet is changing as society advances and as time passes. We used to believe that Pluto was a planet which orbits the sun, but in a weird way since it’s orbit is quite odd compared to other planets in our solar system. Pluto is different such that, it has five moons and crosses Neptune’s orbit. Not only does it do that, it is quite small in contrast to the other celestial body in our solar system. As society advances, we question the definition of a planet and Pluto’s status in our solar system. Our crave for knowledge and curiosity about what’s around us motivates us to explore the unknown. Our desire to learn more is due to the fact that people

It was discovered in Arizona, USA and an eleven year old girl from England won the naming contest, naming the new planet "Pluto" after the Roman god of the underworld. Astronomers are not certain, but they think that the composition is similar to Triton's with 70% rock and 30% ice. It has a low pressure atmosphere containing nitrogen, methane, and carbon dioxide. It is about one sixth the mass of Earth's moon and has five natural satellites, it's most famous moon being Charon. The other four moons were discovered in the 21st century, named Nix, Hydra, Kerberos, and Styx. There is a spacecraft called New Horizons that has just made it to Pluto. This fairly recent discovery, however, did not even make a full revolution around the sun before it was demoted to a dwarf planet for not complying with the last of the three planet requirements: "It has cleared the neighborhood of its orbit of any other space debris." It has now been named a dwarf planet, a title given to celestial bodies what are missing just one of the three requirements to become a

"Pluto has strong atmospheric cycles, it snows on the surface, the snows sublimate and go back into the atmosphere each 248 year orbit," said Alan

Known as a dwarf planet, Pluto is in the Kuiper belt, a ring of bodies beyond Neptune. It was the first discovered Kuiper belt object.

Secondly,what is pluto,a planet,a planet oid or a comet? The outward-bound voyager one and two spacecraft were both launched in 1977,which started the drama about Pluto. Pluto is twice the size of Ceres and the largest known asteroid.

Pluto’s orbit is very different from the other planets in the solar system. There are three criterias you have to meet in order to be considered a planet. It has to orbit the Sun, be in the shape of a

In addition to the dimensions, Pluto has an irregular orbit compared to the other planets. Its orbit is not round or circular; it is more like an oval shape and its orbital incline is more than 17 degrees of the elliptic. Secondly, the location of Pluto is relevant in its

In comparison to Earth, Pluto is about 39 times further away, and therefore, it takes Pluto 248 Earth years to complete one orbit (Landau, Pluto 19). Compared to Earth’s 24 hours in a day, “a day on Pluto lasts 153 hours, or about 6 Earth days” (“Solar System Exploration: Pluto: In Depth.”). Pluto is also only 1,400 miles wide, which is “about half the width of the United States, or 2/3 the width of Earth’s moon” (“Solar System Exploration: Pluto: In Depth.”). Since Pluto is less dense than Earth, Pluto’s mass is an astonishing “one-sixth that of Earth’s moon” ( “Solar System Exploration: Pluto: In Depth.”). When New Horizons visited Pluto, it was also discovered that Pluto has a “heart shaped glacier that’s the size of Texas and Oklahoma” (“Solar System Exploration: Pluto: In Depth.”) and “mountains as high as the Rockies” (“Solar System Exploration: Pluto: In Depth.”). Overall, Pluto is much smaller and less dense than Earth, setting it apart from the other planets which are on a larger scale.

Pluto is a small planet that is very distant from the sun and extremely different from Earth. It is only 2,372 kilometers (1,474 miles) in diameter, has a retrograde (backwards/east to west) orbit, and has about one fifteenth of the gravity of Earth. So, a person who weighs 100 pounds on Earth would only weigh roughly 7 on Pluto. On Pluto, one day is about 6.39 days on Earth. Meaning within
