Dwarf Planet Pluto

Pluto's diameter is 2374 kilometers. or 1,475 miles. Pluto has about the same amount of land as Russia.

It is now widely accepted that Pluto should not be classified as a planet, because more bodies more massive than it were discovered beyond its orbit. Also, it seems that it has characteristics similar to other objects in the Kuiper belt.

No. Gas giants are made primarily of hydrogen and helium. Such an atmosphere could not support enough oxygen for human life, as even if enough could be brought together, it reacts with hydrogen as soon as enough heat is introduced.

Well, you can't go to Pluto, on foot, you have to go by rocketship, I would say..... there is ummmmmmm....... 6 month's, I don't know how many km that is so, don't ask me! Thank you.

Because it was way too small to be a real planet.

Some may be annoyed by my nit-picking. It is not that Pluto was singled out and redefined as a dwarf planet (and by the way it is not Pluto's size that is at issue). A definition of planet was decided upon, and according to the definition Pluto does not meet criteria to be considered a major planet. Pluto has not cleared its neighborhood (the Kuiper Belt) of debris. It may well be that Pluto's then-disputed place among the major planets fueled the need for a definition, but the definition was needed and the current one seems reasonable to most.

It doesn't follow the rules of a planet because there are hundreds like it. Humans didn't know it before because our technology has evoluted since the discovery of space. That is what my science teacher told me.

That is a great answer! and that about wraps it up.

Kuiper belt

I personally do not agree, mainly because then the astrologers who used Pluto as one of their items in their charts will now have to retire from their work.

Pluto was discovered in 1930 by a lucky accident. It was predicted mathematically that there was a planet beyond Neptune. Not knowing this, Clyde W. Tombaugh at Lowell Observatory in Arizona did a very careful sky survey which turned up Pluto anyway.

On January 19, 2006 a space probe was launched and sent to Pluto. It was expected to reach Pluto in 2015. So it would take about 9 years to get to Pluto.

9 earth days

Yes - in fact, anything that has mass will exert a gravitational force (including comparably small objects, like a human being). Pluto's force of gravity is equal to 0.58m/s2, which is about 6% that of the gravity on Earth.

The New Horizons spacecraft. It will reach Pluto July 14th 2015.

In August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet. It was downgraded because it did not meet the three criteria the IAU uses to define a full-sized planet. Pluto meets all the criteria except one: it hasnâ??t cleared its neighboring region of other objects.

It would take approximately 2-3 hours to walk 12.5 kilometers on flat terrain at a moderate pace of about 4-6 km/h. Keep in mind that factors such as individual fitness level and stops along the way can affect the actual time taken.

Pluto is not considered a planet because it has not cleared other objects out of its orbit. It has a composition much like that of a comet, consisting of various ices, and so is not a terrestrial planet.

Dr. Tyson's interview is not well-organized, while his preface is clearly organized so the reader can easily understand it.

It's because Pluto is so far away that the space shuttle NASA sent out to take close up pictures, still isn't there and it's still got a long way to go (probubly neer Saturn by now).

The International Astronomical Union changed the classification of Pluto in August of 2006. They downgraded it from a planet to a dwarf planet.

Pluto does not meet the criteria set by the International Astronomical Union to be classified as a planet. It has not cleared its orbit of other debris, a key requirement for planethood. Instead, it is now considered a dwarf planet.

Both Pluto and Jupiter are planets in our solar system. They are both part of the outer planets, with Jupiter being the largest planet and Pluto being the smallest. They also have multiple moons orbiting around them.

No, no spaceship has landed on Pluto. The only spacecraft to have visited Pluto is NASA's New Horizons probe, which flew by the dwarf planet in July 2015 and conducted a close flyby to gather data and images.

All of the following bodies orbit the sun:


-- All of the planets on our solar system, including the earth
-- All the natural satellites of all the planets, including earth's moon
-- The body of every human being, alive or dead, ever born on earth
-- All of the asteroids
-- All of the members of periodic meteor showers
-- All of the periodic comets
-- All of the bodies in the Oort cloud
-- All of the artificial satellites ever constructed on earth,
(whether or not they successfully achieved earth orbit, or were even launched)
-- All but a couple of the space probes ever constructed on earth and launched into space
-- All of the auxiliary hardware, third-stage rocket motors, etc. ever used to launch satellites and space probes
