- Pluto was discovered back in 1930. At that time, it was called the ninth planet in our Solar System, and it stayed that way up until 2006. Nothing changed about Pluto to make it not a planet. The definition of what makes a planet was changed, and Pluto no longer fits the definition.

Why did NASA decide to send the New Horizons spacecraft to Pluto, when there are bigger and more complex planets to be explored closer to us? Pluto was a planet when New Horizons was launched. It's much like asking why there were missions sent to explore Mercury, Mercury is not complex from a geologic standpoint. Pluto was the final world, final planet before it got demoted, so people just wanted to send a mission to explore this planet.

Dwarf Planet Pluto: Facts About the Icy Former Planet In 2006, Pluto was reclassified as a dwarf planet, a change widely thought of as a demotion. The question of Pluto's planet status has attracted controversy and stirred debate in the scientific community, and among the general public, since then.ince Pluto is so far from Earth, little was known about the dwarf planet's size or surface conditions until 2015, when NASA's New Horizons space probe made a close flyby of Pluto.

Why Pluto is No Longer a Planet no, they are dwarf planets. Pluto is not a planet, it is a dwarf planet. The difference is that dwarf planets have an eccentric or elliptical orbit, and that they are small. t … he dwarf planets in our solar system are kuiper belt objects.he Earth formed 4.5 billion Years ago. The Earth was a dead planet fore 4.5-3.5 = … 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The beginning of life is called Abiogenesis.

Explore Pluto Student Planet Facts. Pluto is a dwarf planet far from the sun. Here are some facts and other places you can find information about Pluto. Pluto is a small rocky object that lies at the very edge of the solar system. The planet is so far out it takes light from the sun about 5 and one half hours to reach Pluto in contrast to the 8 minutes it takes to reach Earth.

Why is Pluto no longer a planet? Most recently, Alan Stern challenged Neil deGrasse Tyson to a debate on the matter in 2014. The flyby of Pluto is unlikely to provide any information relevant to a change in Pluto's status. But it will bring into clear focus once more what is, and what isn't, meant by the term planet.

What kind of a planet is Pluto? Pluto received a new designation in 2006 as a Dwarf Planet,  formerly a planet but now listed in the Minor Planet Catalogue. It  is also categorized as a Trans-Neptunian Obj…ect and sometimes  called a Plutoid or Ice Dwarf.

Why is Pluto not a planet? Even though Pluto is a dwarf planet, and no longer officially a planet, it'll still be a fascinating target for study. And that's why NASA has sent their New Horizons spacecraft off to visit it. New Horizons will reach Pluto in July 2015, and it will capture the first closeup images of the (dwarf) planet's surface.ny object that doesn't meet this 3rd criterion is considered a dwarf planet. And that makes Pluto a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit.

What New Horizons reveals about Pluto Pluto's demotion to dwarf planet status was controversial but scientifically required. The IAU requires bona fide solar system planets to meet three criteria: (1) they orbit the sun; (2) they are big enough that gravity makes them round; and (3) their neighborhood is not filled with rival would-be planets.

Pluto Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered.

What makes a planet? There are many things that make Pluto quite different from the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. But one difference is truly fundamental, and it explains why Pluto is not classified as a planet.luto was considered a planet for only 75 years, and questions about its planetary status had been raised for more than 10 years. Compare that to the thousands of years during which schoolchildren were taught that planets revolved around the Earth.

Dwarf Planets Personally, I agree that objects like Pluto should be classified separately from the other eight Planets. However, I don't much like the term Dwarf Planet; I think Planetary Remnant is more descriptive. It conveys the reality of Pluto's existence, that it is the largest bit of a planet that didn't quite form properly.

- Pluto is likely the largest and most-massive member of the Kuiper belt and the largest and the second-most-massive known TNO, surpassed only by Eris in the scattered disc. Originally considered a planet, Pluto's status as part of the Kuiper belt caused it to be reclassified as a dwarf planet in 2006.he Kuiper belt was named after Dutch-American astronomer Gerard Kuiper, though he did not actually predict its existence. In 1992, 1992 QB1 was discovered, the first Kuiper belt object (KBO) since Pluto.

Why is Pluto not a planet? Pluto is only 0.07 times the mass of the other objects in its orbit. The Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit. Any object that doesn't meet this 3rd criterion is considered a dwarf planet. And that makes Pluto a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit. And until Pluto crashes into many of them and gains mass, it will remain a dwarf planet. Eris suffers from the same problem.

- A large body that meets the other criteria for a planet but has not cleared its neighbourhood is classified as a dwarf planet. This includes Pluto, which is constrained in its orbit by the gravity of Neptune and shares its orbital neighbourhood with Kuiper belt objects.

- The universe is what it is, not what we want it to be, and science must always be open to correcting its mistakes. Moreover, historically, the Pluto situation has occurred before in the solar system. Two centuries ago, in 1806, William Herschel’s discovery of the 7th planet, Uranus, was exactly 25 years in the past.

How Cold is Pluto? But in 2006, Pluto was reclassified as a dwarf planet due to its mass and the fact that it had failed to sweep its orbit clear early in its formation. As a Kuiper Belt Object, Pluto is one among millions of rocks and ices, all bearing similar temperatures.
