Which characteristics of a planet does Pluto fail?
Pluto fails the third characteristic: it has not cleared its neighborhood. This means that it has not cleared the asteroids and other objects that lie within its orbit. ("Clearing" usually means the object is attracted by the planet's gravity and eventually becomes part of the planet).
"Apogee" and "perigee" are the points in the orbit of an Earth satellite where the
orbiting body is farthest from and nearest to the Earth, respectively. I don't think
that's what you're looking for. I suspect you're asking for the point in its orbit where
Pluto is farthest from the Sun ... the point called its "Aphelion".
Pluto's orbit is quite eccentric, that is, non-circular:
-- At aphelion, it's 7,311,000,000 km (4,543,000,000 miles) from the sun.
-- At the other extreme, called "perihelion", it's 4,437,000,000 km (2,757,000,000 miles) from the sun.
-- Pluto's orbital period is 246 Earth years. Since its discovery in 1930, Pluto
has completed less than 1/3 of a single orbital revolution.
Uranus and Neptune are the Ice Giants.
Mars also has ice as too does Mercury and Earth.
Is Pluto a big planet or small planet?
Pluto is relatively small as planets go; it is officially categorized as a dwarf planet.
How long does it take to drive from the sun to Pluto at 112 km per hour?
It's not posible as they havn't built the road yet.
When they do it will take to 484,123 hours to drive 5,906,292,480 kilometres.
Will the new horizons spacecraft reach Pluto in 2015?
Yes, the New Horizons spacecraft reached Pluto in July 2015, becoming the first spacecraft to explore the distant dwarf planet up close. It provided valuable data and images of Pluto and its moons before continuing its journey into the Kuiper Belt.

How much is 424 light years to an earth year?
Light Years isn't a time, it's a distance or a length.
1 Light year is the distance that light travels in one year.
That is = 9,460,730,472,580,800 metres (in one year)
= 9,460,730,472,580.8 kilometres (in one year)
Should bowls of food be passed clockwise or counter clockwise at the dinner table?
Bowls should not be passed at the table at all. In American table manners, the servers should serve you from the left (either filling your bowl or delivering one already full) and remove the finished bowl from your right.
The magnitude of the force would decrease greatly.
The 'g' in the question might refer to any number of things. I've selected one.
The acceleration of gravity on the surface of Pluto is 0.583 m/s2 . That's the
quantity known as " One G " on Pluto. On Earth, it would be called "0.059 G" .
Is there any place on the earth where you can see dawn and dusk almost at the same time?
- This phenomenon would most likely be most visible at the poles (north and south).
- Living in Iceland, there were times during the "summer" when the sun never actually set, it just moved around the horizon in a weird undulating pattern.
- From the other perspective, there are locations just beyond the Arctic and Antarctic Circles when the Sun will briefly pop up above the horizon and immediately set again.
- Yes, in Alaska during the summer the sun sets for about 1 to 2 hours if you call that at the same time.
- Yes, through super refraction at high latitude. One Sunrise in the North Norwegian, an image of the sun was clearly visible 180 degrees at an altitude of approx 10 degrees setting, as it got closer to the horizon it broke up.
How many years has Pluto been considered a dwarf planet?
As of 2013, Pluto has been classed as a dwarf planet for 7 years.
How would the sun look from Pluto?
The sun would look much smaller than it does from Earth but still bright.
What could be responsible for high fuel consumtion in a 1993 Camry 2.2?
It could need a tune up and filters changed or if the check engine light is on have the codes read. Also, check for leaks.
How long does it take a satellite to get to Pluto?
New Horizons probe was launched in 19 January 2006, and is projected to make a flyby of Pluto 14 July 2015. Its travel is thus expected to take about nine and a half years.
The New Horizons mission utilizes gravity assist (aka gravitational slingshot) maneuver near Jupiter to gain more speed, and to save on launch weight.*
While technically journey can be made much faster - and somewhat more directly - than New Horizons one, its launch would require far larger rocket and boosters and thus be prohibitively expensive.
Travel to Pluto might take slightly longer in the near future as Pluto will be heading toward it's aphelion (and thus distancing itself from earth) the travel time (for a spacecraft with significant scientific payload) in the near future will be somewhere around, or slightly below, ten years.
With more advanced technology, such as VASIMR thrusters, the travel time could theoretically be cut to less than a year.
* Increased launch weight generally means more fuel, which in turn equals more speed (in form of more thrust)
If traveling at the speed of light how long would it take to travel 4 light years?
The speed at which you travel has a direct bearing on the time required.
Ignoring relativistic effects, estimates of the solution may be derived by direct application of the Newtonian laws
of motion, somewhat as follows, to wit:
Speed . . . . . . . . . . . . . . Time required to travel 4 light-hours
c (light speed) . . . . . . . . . 4 hours
0.001c (300,000 m/s). . . . 40 hours
0.000001c (300 m/s) . . . . 400 hours
60 mph. . . . . . . . . . . . . . . 5,100 years
What minor members of the solar system are thought to have formed beyond the orbit of Pluto?
The most important part of a solar system is the sun at the center of the system. The sun is the foundation that keeps the solar system from flying off in different directions out into space. But more importantly Gravity is what keeps the planets in place due to the size of our sun.
What was Pluto called before it was officially named?
"Planet X". In the early 1900's, noted astronomers Percival Lowell and William Pickering used the 1840 mathematical model of Urbain LeVerrier to predict locations for a planet that would explain the orbital perturbations of the planet Uranus, which did not seem possible due to Neptune alone. Lowell called it 'Planet X' and estimated its size as large as Neptune or larger. In 1929, the search fell to Clyde Tombaugh, who located Pluto in 1930 (oddly enough, a photograph by Lowell in 1915 was found to have a faint image of the planet, once its location was known).
Do natural disasters occur on Pluto?
It is unknown if natural disasters occur on Pluto. Due to the amount of time it would take to get there (23years) mankind has been unable to explore the surface of the dwarf planet. But satellite pictures don't show any type of storm.
Do you see any value in questioning and ultimately changing Pluto's planet status?
There was not any good reason for the International Astronomical Union (IAU) to define the term "planet" as it did, or WHEN it did. There had never been a formal definition of the word "planet". The IAU defined "Planet" with three criteria;
1. Orbits a star, not another planet
2. Has reached hydrostatic equilibrium; meaning, its own gravity has squashed it into a spherical shape (or nearly so).
3. Has "cleared its orbit" of other objects, meaning that there are no other objects traveling in the same orbital path.
It is this third requirement that caused Pluto to be demoted from "planet" to "dwarf planet". There are other objects in the Kuiper Belt which potentially could match Pluto's orbit. In fact, by this third criteria, the Earth itself doesn't really qualify as a "planet"; there are near-Earth asteroids that orbit in paths that are not dramatically different from ours.
Part of the controversy has been that "recent" (at the time) discoveries of other Kuiper Belt objects which are larger than Pluto itself is. Haumea, Eris, and Makemake orbit further out from the Sun and are larger than Pluto. For that matter, the former asteroid Ceres is also larger than Pluto. All five of these objects are now called "dwarf planets".
It seems likely that the next meeting of the IAU will reconsider the status of Pluto, but there's no way of knowing what the decision will be. The IAU is open to any astronomer, but only the ones who attend the meetings get to vote; last time, about 3% of the members actually attended and voted.
Why did scientists change Pluto's classification from a planet to a dwarf planet?
In 2006, the International Astronomy Union (IAU) determined how a planet should be defined. This definition states that a planet is a celestial body that meets the following three criteria:
1. It is in orbit around the Sun
2. It has achieved a (nearly) spherical shape
3. It has "cleared the neighbourhood" around it's orbit
The third requirement essentially means that the celestial body has become gravitationally domininant, and that there are no other objects of comparable size (excluding any satellites) within it's vicinity in space. Pluto failed to meet this third requirement, which demotes it to the status of a dwarf planet.
Without the third requirement, a number of celestial bodies within our solar system would, technically, have to be added to our list of planets, including Ceres, Eres, Haumea, and Makemake (all of which are classified as dwarf planets). There are at least six additional objects that could also be added to this list (including 2007 OR10, Quaoar, Sedna, Orcus, 2002 MS4, and Salacia), though the IAU has yet to officially declare these as being dwarf planets.
Pluto. It is now considered a dwarf planet.
When was Pluto reclassified as a dwarf planet?
On August 24, 2006, Pluto was reclassified by the International Astronomical Union (IAU) as a "dwarf planet", a classification shared by the asteroid Ceres and three trans-Neptunian Kuiper Belt objects : Eris, Haumea, and Makemake. (Kuiper Belt object Sedna is a current candidate as well.)
