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.

Why is Mercury still a planet and Pluto isn't?

At present, pluto has been and still is recommended as a dwarf planet. now i should introduce you to the definition of dwarf planet:a dwarf planet is something that doesn"t exist as a planet in the space.It"s something other than a planet

Is Pluto the largest moon?

No. First of all, Pluto is a dwarf planet, not a moon. Second, Pluto is actually smaller than seven of the moons in this solar system.

Why was Pluto considered the 8th planet?

Neptune and Pluto have different orbits. Neptune is sometimes further away than Pluto. If you read recent debates, the planet Pluto may have a different identification other than planet.

Nowadays Pluto is classed as a minor planet and isn't included as one of the eight major planets. In the past, when Pluto was included it could have been classed as either the 8th or 9th planet because the orbits of Pluto and Neptune vary so that at some points Pluto is nearer to the Sun than Neptune and vice versa.

Is Pluto a moon or a planet?

no it's a dwarf planet

I would think that it is a dwarf planet, but its moon, Sharon, is nearly as big as it, so some MAY argue that Sharon is a dwarf planet and Pluto is the moon, but considering Pluto is slightly bigger than Sharon, I would think that Sharon would orbit Pluto rather than Pluto orbiting Sharon.

Which is colder Earth or Pluto?

The temperature range on Earth is from about minus 90°C to 58°C (-130°F to 136°F)

The temperature on Pluto is from about minus 240°Cto - 218°C (-400°F to - 360°F). Pluto is so cold that the gases of its atmosphere freeze onto the surface when it is farthest from the Sun.

What is the atmosphere of Pluto?

Pluto has orbited close to Earth and the sun during the late 20th and early 21st centuries. While Pluto is this close to the sun, some nitrogen with small amounts of carbon monoxide and methane that were frozen on its surface have warmed enough to become gaseous, forming a thin atmosphere. Much of Pluto's atmosphere is expected to freeze and collapse once again as it moves away from the sun over the next 10 to 15 years. The complete orbit of Pluto takes almost 250 years, and during most of this time the atmosphere is thought to be almost non-existant. Wikipedia has some additional information and a link is provided.

What changed about Pluto in 2006?

In 2006, pluto's classification was changed to "dwarf planet". This removed it as one of the nine planets in our solar system. It was done so by the IAU (international astronomical union). The main reason for this is due to the orbital path of Pluto as it crosses Neptune's and thus does not fit the IAU's definition of a "planet".

Why was Clyde Tombaugh searching beyond Neptune?

Clyde discovered Pluto with a device called a "blink comparator." In its time, it was top-of-the-line technology, circa 1930.

Full-sky or All-sky surveys were taken from time to time on old-fashioned photographic plates back in the day. Most stars move imperceptibly over several human lifetimes, because they are so far away; but planets, they are much closer to Earth. Even distant Pluto moved enough to be captured by 1930's technology.

The blink comparator focused the image of two different photo plates taken at different times, but of the same region of the sky, rapidly back and forth. Any planet, or "wandering star" from the Greek language, would manifest itself as movement in the rapidly changing views of the comparator. Easy enough for a human to detect.

Especially one so talented as Clyde Tombaugh. And that is how he found it.

What will happen if you touch Pluto?

If you are talking about touching it with your bare hand, you're entire body would freeze solid the moment your space suit was breached.

If you are talking about touching it while wearing a spacesuit, then nothing would happen.

How many years would it take for you to travel from the sun to Pluto?

The closest Pluto gets to the Sun is 4.4 billion kilometers, which means that light from the Sun always takes longer than 4 hours to reach Pluto. For a rocket vehicle travelling at the speed that astronauts went to our Moon (less than 40,000 km/hr), it would take over 12 years to reach Pluto!

How many moons does Pluto have?

Phobos, the inner of Mars' two natural satellites, is in spin-orbit resonance, and

like Earth's moon, its axial rotation and orbital revolution periods are equal.

The period is 7hours 39.2minutes

What are the travel times and dates that desicribe the probes or missions to the planet Pluto?

i reallt know what the answer is but i wish i knew and my mood is geeky.

There's only one probe. That's "New Horizons" and it doesn't get to Pluto until year 2015. It was launched in 2006.

What season can you see Pluto?

Now we come to the last planet in our Solar System, Pluto. The temperature of the planet is a frosty minus 233 degrees Celcius. The seasons on Pluto are quite long. A summer on the planet occurs when the planet is at its nearest to the sun and lasts about 50 years. This is also the only time when the planet's frozen surface of methane and nitrogen vaporize by the small amount of heat from the Sun to create somewhat of an atmosphere. By 2020, the atmospheric gases of Pluto will once again be frozen to the surface of the planet as it makes its way away from the Sun and will stay that way for more than a century. The long slugish seasons of the planet are due to Pluto’s 248 year orbit. For 20 years of Pluto’s orbit, the planet is actually the eighth planet from the Sun as it passes by Neptune’s orbit. Right now Pluto is ranked the eighth planet, but will only be there for a short time because in 1999 Neptune will regain its rank. Although Pluto may look like it passes through Neptunes path, it is actually millions of kilometers away.

Why is there no Pluto?

Pluto is so lonely because its is the last planet in the solar system and it is so small. Also technically, Pluto is not really considered a planet anymore. So Pluto's so lonely because of all those reasons.

Does Pluto have any volcanoes craters or canyons?

Pluto appears to have two cryovolcanoes.

A cryovolcano (colloquially known as an ice volcano) is a theoretical type of volcano that erupts volatiles such as water, ammonia or methane, instead of molten rock. ... Cryovolcanoes may potentially form on icy moons and other objects with abundant water past the Solar System's snow line (such as Pluto).

Why do Neptune and Pluto cross paths?

About once every 248 years, Pluto moves nearer to the sun than Neptune, and stays that way for about 20 years. This last happened between January 1979 and February 1999 and so it won't happen again until about 2227.

How was Pluto destroyed?

Pluto did not disintegrate. It is still there. The only thing that has changed is a new formal definition of a planet, and Pluto did not make the cut.

Do Pluto orbit is almost perfectly round?

No, in fact it has the most elongated and tilted orbit in the whole solar system

How many pounds does a case of soda weigh?

If one can is 16 oz. wouldn't you multiply that by 36 (the number of cans in a case) and get your weight?

cans and bottles are listed by volume, not weight (ie Fl. Oz).

The contents may weigh more or less than 1 oz per fl oz.

plus there is the weight of the containers.

and 36 in a case?

Why are neptune and Pluto so cold?

Mercury

Venus

Earth

Mars

Jupiter

Saturn

Uranus

Pluto

When has Pluto been visited by astronauts?

No. The only world other than Earth where people have been is the moon. The first spacecraft to reach Pluto will be New Horizons in 2015; an unmanned spacecraft. Even then it will only fly by; it will not land.

Can animals survive on Pluto?

No, there is not enough atmosphere on Pluto to breathe. Pluto is also too cold for a polar bear.

How long does it take to adopt from the US?

That depends on numerous factors. If you are adopting an infant, you can expect your wait to be longer...especially if have specifics. If you want to adopt through foster care, you can expect a wait of anywhere from 2 months to 2 years, again, depending on your specifics. For example, if you only want a white child under 2 years old, expect that your wait will be far longer. If you are fine with adopting a bi-racial, black, hispanic child who is 2+, then there are many more children who will be considered for placement....and you wait time would be on the shorter side. Most of your wait time is agency delay. For instance, once we completed all of our forms and background checks, it took 3 months for our child to be placed....BUT, the paperwork and background checks and homestudy took about 9 months to complete.
