Dwarf Planet Pluto

A dwarf planet that was the 9th planet from the Sun in our solar system until 2006 when it was determined it did not satisfy the requirements of being a planet.

Who decides if a planet is a planet?

The IAU decides on what is a planet under new guidelines

The International Astronomical Union decided that upon further discovery of smaller body's of planet like material in our solar system but far from the sun or Neptune's orbit of the sun that all new planets found would probably be small and are to be named as dwarf planets.

This was prompted recently by the discovery of the then named Xena now Eris our 5th dwarf planet

Eris is larger and rounder in shape than Pluto which prompted the Question When is a Planet not a planet? in 2006 they issued new guidelines where Pluto lost it's planetary status and was demoted to a dwarf planet.

If nibiru has an orbit of 3600 years how far out is its orbit?

Nibiru's alleged orbit of 3,600 years is a claim without scientific evidence. However, if we assume it does exist, its distance from the Sun would depend on the specifics of its orbit shape and size, which are unknown. Without accurate data, it is impossible to determine the exact distance of Nibiru's orbit from the Sun.

Does pluto have more moons than any other planet?

No, the latest estimates are 5 moons for Pluto and over 60 each for Jupiter and Saturn.

What will the earth be like in 5000000 years?

It is difficult to predict with certainty, but based on geological processes, the earth may have undergone significant changes in its landmasses, climate, and biodiversity. Continents may have shifted due to plate tectonics, sea levels might be different, and new species may have evolved while others become extinct.

How many earths can fit inside jupitter?

Approximately 1,321 Earths could fit inside Jupiter, given its massive size and volume.

How close does Pluto get to the sun in Perihelion?

The distance between the Earth and the Sun at perihelion is 147,098,074 km

0.9832898912 AU or 91.4 milion miles).

Perihelion is the point of least distance of the elliptical orbit of the Earth from the Sun.

What are the names of two other dwarf planets besides Pluto and where are they located?

Two other dwarf planets besides Pluto are Eris, which is located in the Kuiper Belt, and Haumea, which is located beyond Neptune in the scattered disc region of the outer solar system.

What is the atmesphere on Pluto?

Pluto's atmosphere is very thin, composed mostly of nitrogen, with small amounts of methane and carbon monoxide. It is unable to support human life as the pressure is extremely low and temperatures are very cold.

Some scienctist have suggested that Pluto is not a planet what evidence supports such an idea?

One key piece of evidence is that Pluto does not clear its orbit of debris, a criterion used to define a planet. Additionally, Pluto is much smaller and less massive than the other planets in our solar system, more closely resembling other icy bodies in the Kuiper Belt. These factors led to its reclassification as a dwarf planet by the International Astronomical Union in 2006.

Which planets have moons and which do not?

All planets in our solar system except Mercury and Venus have moons. This means that Earth, Mars, Jupiter, Saturn, Uranus, and Neptune all have moons orbiting around them. Mercury and Venus are the only two planets in our solar system that do not have any moons.

Did any planets get destroyed?

Jupiter can be destroyed but why would you want to?

In about 5 billion years time, when our Sun turns into a red giant, it will start to shed it's outer layers into the outer Solar System. These solar winds will start to strip the outer atmosphere of Jupiter away from it's core. Whether it will be enough to decimate Jupiter is unlikely, but Jupiter will, when out Sun dies, become nothing more than a dead planet.

Can a dwarf planet be a gas giant?

Under the current definition of a planet, yes it can! If a gas giant were to share its orbit with other objects of significant mass (other than moons, comets or asteroids), it would definitely qualify as a dwarf planet. In order to be a planet, it would have to "clear the neighborhood" until it was the dominate influence in its orbit.

How have illustrations of the solar sytem been misleading?

Illustrations generally fail to represent the sheer size and massive proportions of the solar system. The distances between objects are often imprecise and the distances are not always proportional, giving viewers of that particular illustration an incorrect idea of our distance from other planets.

What is the difference between a thin and thick atmosphere?

A thin atmosphere has low pressure and density, like on Mars, while a thick atmosphere has higher pressure and density, like on Earth. Thick atmospheres can trap heat and support life, while thin atmospheres make it harder for planets to retain heat and protect against harmful radiation.

What is Ananke's rotational period in earth days?

Ananke's rotational period is around 45.7 Earth days. It rotates on its axis at a slower rate compared to many other moons in our solar system.

How old would you have to be to witness one complete revolution of the planet Pluto?

To witness one complete revolution of the planet Pluto, you would have to be at least 248 years old.

How much would you weigh on Pluto if you are 107 pounds on earth?

Well if u calabrate the calabrated conjunction that comes out o about 78.3333 and so on

Why was the term dwarf planet created?

The term "dwarf planet" was created to classify celestial bodies that are similar to planets but do not meet all the criteria to be considered full-fledged planets. It was implemented to describe objects like Pluto, which was reclassified from a planet to a dwarf planet by the International Astronomical Union in 2006.

Is there life on Eris the dwarf planet?

Eris is way too cold for life to exist. Life needs energy, and there is very little energy on such a small object so far from the sun. In fact, the same gases that make up earth's atmosphere are frozen solid on Eris.

What is the difference between a bound orbit and an unbound orbit around the Sun?

A bound orbit is a closed path around the Sun where an object is gravitationally bound to the Sun, like the planets in our solar system. An unbound orbit is when an object travels past the Sun once and does not return, like a comet that enters the solar system from afar and leaves after its close approach to the Sun.

How long has Twitter been around?

Twitter was launched in March 2006, making it around 15 years old as of 2021.

What were the names of all the probe sent to Pluto?

Actually, no probes have ever been sent to Pluto. Even Voyager 1 and 2, which flew beyond the orbit of pluto in 1989, didn't do a fly-by of the planet (it was elsewhere in it's orbit at that time, and there were no plans to visit Pluto anyways).

How the planet alignment will affect planet earth?

Nobody actually knows what is actually going to happen on 12/21/2012 but most believe nothing but what the myans belevied was a solar allingment will change the poles.

Why is Pluto called a dwarf planet andnot a real planet?

Pluto is classified as a dwarf planet because it has not cleared its orbit of other debris, unlike the eight classical planets that have. Also, its size and characteristics are more similar to other objects in the Kuiper Belt rather than the traditional planets in our solar system.
