How come Pluto was erased as a planet,?

Answer 1

Pluto has always been too small and too far away, just a bold speck of dust in an asteroid belt. Don't worry, they're working on a replacement.

Answer 2

Pluto was originally designated a planet due to the fact that astronomy and our ability to observe the outer solar system was limited. Pluto's location is one factor involved in this decision. Pluto is located in an asteroid belt surrounding the entire solar system. This belt is similar to those that surrounded the sun long ago, before becoming the planets we know. The belt outside of our solar system does not have enough gravity to create a single planet, so a number of larger objects were formed. Pluto is one of these objects. With Pluto are several large asteroids that follow a similar path. If Pluto was to be designated as a planet, these objects would have to be classified as well. In the end it has been determined that Pluto is an asteroid in a belt of debris surrounding our solar system.

Answer 3

Much-maligned Pluto — named for the god of the underworld — doesn’t make the grade under the new rules for a planet: “a celestial body that is in orbit around the sun, has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a ... nearly round shape, and has cleared the neighborhood around its orbit.”

Pluto is automatically disqualified because its oblong orbit overlaps with that of much larger Neptune.

Instead, it will be reclassified in a new category of “dwarf planets,” similar to what long have been termed “minor planets.” The definition also lays out a third class of lesser objects that orbit the sun — “small solar system bodies,” a term that will apply to numerous asteroids, comets and other natural satellites.

Experts said there could be dozens of dwarf planets cataloged across the solar system in the next few years.

Answer 4

Because it resides on a different plane than the rest of the solarsytsem, its orbital path is highly elliptical, it actually is in the Kupier Belt, its moon is roughly the same size as it and the center of gravity of the two is between them, and if its a planet then hundreds of other similar objects are planets too.

Answer 5

Because it's dead, so they say. Now it is categorized as a dwarf planet, and no longer considered the 9th planet. There are only 8, which means they have to re-write the books, lol.

Answer 6

We astronomers just couldn't damn take it anymore. We are sick and tired of it being a planet. It is just a glorified asteroid. Everyday it just sits there orbiting our wonderful sun like it is as good as earth. Just makes me sick.

Answer 7

Its to small and far. Plus a dog really dosnt work so much as a planet;)

Answer 8

Because it was acting up and disrespecting the other planets.

Answer 9

cuz they changed the definition of the word planet

Answer 10

i think they say pluto is just a huge ball of ice.
