Pluto Research Papers

Which is the largest of all dwarf planets? Pluto is a dwarf planet in our solar system and has been given the nickname Xena. Pluto was once considered the ninth main planet from the Sun. Scientists discovered Pluto on February 18, 1930 (history.com). Several objects surround Pluto including Nix (Pluto’s natural satellite) and Hydra (Pluto's outermost satellite) , comets, and the constellations “Teapot”, and “Scorpius”. Pluto is a fascinating planet because of its discoveries and missions, composition, and research.

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.

Have you heard about New Horizon’s impending flyby of Pluto? As the spaceship gets closer, it will take pictures of Pluto. Scientists hope that New Horizons will provide new information about the dwarf planet.

NASA’s New Horizons spacecraft has snapped the first ever color photograph of Pluto. The image, shown below, may be a bit blurry, but you can expect more detailed images to emerge as the spacecraft gets closer to the lonely planet on the edge of the Solar System. New Horizons also caught Charon, a moon, in the photograph of Pluto.

In the past the definition of a planet in space was a body that orbits a star, such as the sun, that reflects the star’s light and is larger than an asteroid. This is until new research by new technologies allowed us to learn more and change the definition of a planet. This new information changed the fact that Pluto is no longer a planet, but a dwarf. Dwarfs may confuse many people because it is hard to tell it apart from a planet.

The greatest astronomical discovery that I always remember was the demotion of Pluto from planet to dwarf. Until this discovery, scientists thought that there were nine planets. Muggle school children (and magical school children) remembered the names of the nine planets using mnemonics like "My Very Easy Method Just Shows Us Nine Planets" and "My Very Educated Mother Just Served Us Nine Pizzas" (Wikipedia). These mnemonics were easy ways to remember the nine plants; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. However, in August 2006, the International Astronomical Union met and changed the definition of a planet, thus downgrading Pluto and changing planetary mnemonics forever.

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

Neptune is a fraction smaller than Uranus, it is ‘49,500 kilometres’. It only circles around the sun once every 165 years and rotates one hour quicker than Uranus- just 16 hours. Neptune has at least 14 moons in total, although it is not for certain as Neptune could have more moons. Neptune also has five rings, like the other three planets. It is 4.498 billion

At first glance, it might seem like Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto barely have anything in common, but looking at it closer will help one realize that they have plenty similarities. An example is all of the planets revolves around the Sun. This fact is, of course, obvious, but it surely is one similarity the diverse planets has together. Not only that but the planets also a body that orbits the sun. although Pluto is not as big as the other planets, it was still large enough to have its own gravity, which is what makes it round and somewhat spherical.

Pluto is one of six dwarf planets. There are nicknames for Pluto like dwarf planet or 134340. Pluto was named after the roman god of the underworld. Pluto is also farthest planet from the sun.This dwarf planet has a total of four moons,and thin envelope gasses.Pluto was discovered along time ago,this planet was made with lots of materials,and takes along time to get there.

In 1930, Clyde Tombaugh, an astronomer from the United States, discover what was first believed to be the ninth planet in our solar system, Pluto. For generations, people learned that the planets orbiting the sun ended with the very small Pluto. Only half as wide as the United States, Pluto was always an area of interest to astronomers but it became a major topic of discussion within the public when, in August of 2006, Pluto was demoted from its status as the ninth planet in our solar system to a dwarf planet. To be classified as a full-sized planet, the celestial body must orbit the sun, have a round shape, and be gravitationally dominant. Pluto orbits the sun and is round, but Pluto shares an orbital space with bodies of a similar size, so the planet is not considered gravitationally dominant. Pluto isn’t the only dwarf planet in our solar system, Eris and Ceres are both dwarf planets currently recognized by the International Astronomical Union.

As humans, many unnecessary questions appear in our brain quite frequently, questions that will not really benefit us whenever we find the answer to it, but we are crazy to find that answer anyway. Humans are simply just very curious beings. Growing up, in elementary school, I was taught that there were nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. But today, in the year 2017, there are only eight because Pluto is no longer a planet. Pluto is the smallest and the farthest from the sun, so I predict that is one of the reasons that it can no longer be classified as a planet in our solar system.

Pluto 's life as a planet was very short, lasting only 75 years—which is less than a third of its orbital period. While Pluto independently orbits the sun in a spheroidal shape—two classifications for being considered a planet—Pluto lost its title with the discovery of Eris. Pluto also travels on a different plane than the rest of the planets, and because it has an extremely elliptical orbit, it occasionally crosses Neptune 's orbital path and, therefore, is occasionally closer to Earth than Neptune (Countdown, 2011). As a dwarf planet Pluto is the only binary planet in the system due to one of its five moons being half of its size.

After several hundreds of millions of years of slow, gradual migration, Jupiter and Saturn, the two inmost giant planets, crossed their mutual 1:2 mean-motion resonance of orbital motion. This resonance increased their orbital eccentricities to such an extent, that it destabilized the entire planetary system. The arrangement of the giant planets altered quickly and very radically. Jupiter shifted Saturn out towards its present position, and this relocation caused mutual gravitational encounters between Saturn and the two ice giants, which subsequently propelled the planets Neptune and Uranus onto much more eccentric orbits. These ice giants then ploughed into the planetesimal disk, scattering tens of thousands of planetesimals from their formerly stable orbits in the outer Solar System. This disruption almost entirely scatters the primordial disk, removing almost 99% of its mass, a scenario which explains the modern-day absence of a dense trans-Neptunian population. Some of the planetesimals were thrown into the inner Solar System, producing a sudden influx of impacts on the terrestrial planets: yes! It is the Late Heavy

The terrestrial planets are Mercury, Venus, Earth, and Mars. These four planets are the planets that are closest to the sun. Terrestrial means earthlike; therefore, these planets are all earthlike because they have a solid ground. The terrestrial planets are the middle school years. The knowledge learned here orbits the sun. If the knowledge learned at the sun is not retained, a student may have a
