why does pluto not dominate its neighborhood?
437543
“Cleared the neighborhood” means that the “planet” has to be the dominant gravitational body in their orbit around the sun. This means that the “planet” has to cruise its orbit while consuming or slinging away smaller objects in its orbital path. Pluto is only . 007 times the mass of the other objects in its orbit.

Originally, there wasn't a very precise definition of what it meant to be a planet. When Pluto was first discovered, it was found to orbit the sun on its own (except for its satellite Charon). So Pluto was considered a planet (albeit a small one). ... The object must have "cleared its orbital neighbourhood".

Answer and Explanation: Pluto is not considered to be a Jovian planet because it is a relatively small terrestrial body, rather than a large, gaseous planet.

Discovered in 1930, Pluto is the second closest dwarf planet to the Sun and was at one point classified as the ninth planet. Pluto is the largest dwarf planet but only the second most massive, with Eris being the most massive.

To catch a glimpse of the dwarf planet, you'll need a telescope with at least an 8-inch diameter mirror, according to Sky and Telescope. Even at its brightest, Pluto is not visible to the naked eye and is about 27 million times fainter than Venus.

Dwarf planets So, the reason that many books say that Pluto is a planet, is because for 76 years that was true. Everyone over age 30 knew Pluto as a planet for more than half their lifetimes. In 2015, the New Horizons space probe flew past Pluto, taking the highest resolution pictures ever of the dwarf planet.

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

Discovered in 1930, Pluto was long considered our solar system's ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet. Pluto is orbited by five known moons, the largest of which is Charon.

The new ruling reclassifies Pluto as a dwarf planet and reduces the number of planets in the solar system to eight. Both Eris and the asteroid Ceres are also classified as dwarf planets.

A planet is considered to be dominant if it lies in the sign that it rules on your birth chart. It usually means that these planets have a more powerful influence on the Birth Chart than other planets. ...

(In case you're wondering, though, Mercury is still significantly larger than the dwarf planet Pluto: Pluto's equatorial diameter is just 2,302 km, about half Mercury's width.)

Once Jewitt and Luu discovered the Kuiper Belt, astronomers soon saw that the region beyond Neptune was full of icy rocks and tiny worlds. Sedna, a KBO that's about three-fourths the size of Pluto, was discovered in 2004. It is so far out from the sun it takes about 10,500 years to make a single orbit.

Pluto will cross back over Neptune's orbit again on February 11, 1999 to resume its place as the 9th planet from the Sun for the next 228 years. So will Pluto and Neptune ever collide? No! ... The orbits never actually cross the same point in space.

Just outside of Neptune's orbit is a ring of icy bodies. We call it the Kuiper Belt. This is where you'll find dwarf planet Pluto. It's the most famous of the objects floating in the Kuiper Belt, which are also called Kuiper Belt Objects, or KBOs.

At its most distant, when the two bodies are on the opposite sides of the sun from one another, Pluto lies 4.67 billion miles (7.5 billion kilometers) from Earth. At their closest, the two are only 2.66 billion miles (4.28 billion km) apart.

Pluto, Eris, Haumea and Makemake are all known as "plutoids," unlike the asteroidal dwarf planetoid Ceres. A plutoid is a dwarf planet with an orbit outside that of Neptune.
