Why was Pluto declassified as a planet?
Pluto was declassified as a planet in 2006 because it did not meet the newly established criteria set by the International Astronomical Union for what defines a planet. Pluto's small size and its orbit overlapping with Neptune's were key factors in its reclassification as a dwarf planet.
Why won't Pluto collide with Neptune?
Pluto won't collide with Neptune because they are in different orbits around the Sun, and their paths do not intersect. Their distances from the Sun and their speeds keep them from colliding with each other.
Why isn't Pluto a planet anymaore?
In a sense, it never really WAS a planet. If Eris had been discovered as quickly after Pluto as Pallas was after Ceres, Pluto would never have been considered to be a planet in the first place; astronomers would have simply said "Huh, looks like there's a second asteroid belt out there." At the time Pluto was first discovered it was thought to be a planet. We now know more about it and there are a number of problematic issues: Firstly, it's significantly smaller than was first thought. At one time it was believed to be approximately Earth-sized; it's actually smaller than the Moon. Secondly, it's got a weird orbit. It's got a relatively high eccentricity and a relatively high inclination compared to the planets. It's also in an orbital resonance with Neptune; some of the other planets have near resonances with each other, but none of them have an exact resonance like the Pluto-Neptune one (Pluto completes exactly three orbits for every two of Neptune's). Thirdly, it's not alone out there; there are plenty of other objects of roughly similar size in similar orbits which are clearly NOT associated with Pluto. This is not true of any of the planets (the current definition of "planet" specifically includes this as a requirement). Fourthly, it's not even the BIGGEST of the objects out there; Eris is larger than Pluto. Taken all together, Pluto looks less like it belongs in a group with Jupiter, Uranus, Earth, and Mars, and more like it belongs in a group with Orcus, Sedna, Haumea and Ceres.
Why does it take Pluto 248 earth years to orbit the sun?
It takes such a long time as Pluto is so far from the sun. Not only is its angular velocity very low compared to planets further in, but it also has to travel much further to complete one revolution of the sun.
What is composed of ice frozen gases and rocks?
Comets are composed of ice, frozen gases, rocks, and dust. When they orbit closer to the sun, they form a glowing coma and a tail as the ice and gases vaporize.
Pluto is not lost, its orbit is well understood and there are people who know exactly where it is on any given day.
However Pluto has an orbit that is unusually eccentric, and is inclined by 17 degrees to the ecliptic. That means it is found well off the beaten track where the eight major planets can always be found, near the ecliptic.
How long would it take you to get to Antares going the speed of light?
If I were able to travel at the speed of light, I would arrive at Rigel instantaneously, from my point of view. It would seem longer to you as an observer on earth. Rigel is estimated to be between 700 and 900 light years from earth, so between 700 and 900 years would elapse on earth before my instantaneous arrive there.
Pluto was discovered by Clyde Tombaugh in 1930 at the Lowell Observatory in Arizona. Tombaugh discovered Pluto by systematically searching for unknown objects in the outer solar system using photographic plates.
What is the average surface temperature of dwarf planet Pluto in Celsius?
The average surface temperature of dwarf planet Pluto is about -229 degrees Celsius.
Why has Pluto not classed as a planet?
Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because it did not meet all the criteria to be considered a full planet. One of the criteria is that a planet must clear its orbit of other debris, which Pluto did not do.
What was plutos brothers name called?
Pluto's brother's name is Zeus. Zeus is the king of the gods in Greek mythology and is one of Pluto's siblings.
What are the reasons that Pluto is not the planet?
pluto is no longer a planet because some scientists believed that pluto no longer reched the requirments to be a planet, meaning pluto is to small to be a planet and is now considered a dwarf planet.
If I landed on Pluto, I would experience extremely cold temperatures and a thin atmosphere primarily composed of nitrogen and methane. The landscape would consist of icy mountains, plains of frozen nitrogen, and possibly some active geysers. The view of the distant sun from Pluto's surface would appear as just another bright star in the sky.
When Cassini entered orbit around Saturn did it cause the planet's orbit to change?
No, the presence of Cassini did not cause Saturn's orbit to change. Cassini's own orbit around Saturn was carefully planned to avoid influencing the planet's motion. The spacecraft's gravity was too insignificant to affect Saturn's massive orbit.
When did the Pluto planet blast?
Pluto, which is now considered a dwarf planet, has never "blasted." It is located in the outer region of our solar system, beyond Neptune, and remains relatively stable in its orbit.
What must a planet have which a dwarf planet doesn't?
A planet:
1) Orbits the Sun or some other star
2) Gravity has to shape it into a sphere &
3) Have an orbit that does NOT link up to another planet's orbit
A dwarf planet is classified if it does not have one of these 3 things. Reason 3 (like most other dwarf planets in our Solar System) is what makes Pluto a dwarf planet (since some of it's orbit links up to Neptune's orbit)
What is the similarities and differences of the planet mars and Pluto?
Similarities
• Both celestial objects are located in our Solar System and orbit around the Sun in relatively elliptical orbits compared to the planets.
• Until August 2006, both Mars and Pluto were considered planets by mankind.
• Both celestial objects are terrestrial, which means they have a rocky surface.
• Both celestial objects are close to some kind of belt in our Solar System (Mars is close to the asteroid belt; Pluto is close to the Kuiper Belt).
• Both celestial objects have atmospheres composed primarily of CO2 (carbon dioxide).
• Both celestial objects' temperatures reach well below zero in both Fahrenheit and Celsius degrees.
• Both celestial objects have moons.
• Both celestial objects have a tilt and thus both have seasons.
Differences
• Mars is a planet; Pluto is a dwarf planet.
• Mars is located in the inner Solar System; Pluto is located in the outer Solar System.
• They are different in mass, density, and gravitational pull.
• They are different in their relative distances from the Sun.
• They are different in their rotational and orbital periods.
• Both are different in the amount of moons they have (Mars has 2; Pluto has 5).
• Mars has been studied by many unmanned missions, but to date, Pluto hasn't been visited by an unmanned mission, and this will stay that way until 2015, when the spacecraft New Horizonsarrives at Pluto.
• Mars and Pluto's seasons have different lengths (on Mars, a season is less than one Earth year long; on Pluto, a season is at least 50 Earth years long.
Why is Pluto not currently consered as a planet?
Pluto is not considered a planet because it has not cleared its orbit of debris, which is one of the criteria set by the International Astronomical Union for a celestial body to be classified as a planet. Instead, Pluto is classified as a dwarf planet along with other similar objects in the Kuiper Belt.
How long would it take to drink a Fanta?
The time it takes to drink a Fanta can vary depending on the individual's drinking speed. On average, it could take around 5-10 minutes to finish a standard can of Fanta (355 ml).
How many coats does it take to be warm at Pluto?
At Pluto, where temperatures can reach as low as -375 degrees Fahrenheit, wearing several layers of insulated coats or thermal suits would be necessary to stay warm. The exact number of coats would depend on their thickness and insulation properties, but it would likely be multiple layers to withstand the extreme cold on Pluto's surface.
How does the temperature of planet vary with distance from the sun?
The temperature of a planet varies with the distance from the sun because the sun is hot and the closer something is to the sun, the hotter the object gets. The further away the planet from the sun, the colder the planet.
Why Pluto is excluded as a planet by international astronomical union?
Pluto's classification was changed by the International Astronomical Union in 2006 because its small size and orbit do not meet the criteria for a full-fledged planet. Pluto was reclassified as a "dwarf planet" due to these discrepancies.

Why do you think scientists found it difficult to decide how Pluto should be classified?
Scientists found it difficult to classify Pluto because it has characteristics of both a planet and a dwarf planet. Its small size and unique orbit make it challenging to fit neatly into definitions used for celestial bodies in our solar system. This led to debates and discussions about how best to classify Pluto.
Why do gas giants generally lhave lower average temperaturers than the terrestrial planets?
they are farther from the sun
