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.
2,286 Questions
Pluto does not have a significant amount of oxygen in its atmosphere or composition. The atmosphere of Pluto is primarily composed of nitrogen, with traces of methane and carbon monoxide. Oxygen is not a major component of the dwarf planet.
What is Pluto's equatorial diameter?
Pluto was once considered the ninth planet in our solar system, but in 2006 it was recategorized as a dwarf planet. The mean radius of Pluto is 715. 2 miles and the equatorial circumference is 4,493. 7 miles.
Yes, Neptune is larger than Pluto. Neptune is the fourth-largest planet in our solar system by diameter, while Pluto is classified as a dwarf planet and is much smaller in size compared to the eight recognized planets.
Pluto is unique because it is classified as a dwarf planet, it has a highly elliptical orbit that takes it closer to the Sun than Neptune at certain points, and it has five known moons, the largest of which is named Charon. Additionally, Pluto has a thin atmosphere of nitrogen, methane, and carbon monoxide.
NASA launched the New Horizons mission to go to Pluto and it will collect data in 2015. (This is not a "landing", just an observation.) Until then, our best data from Hubble Space telescope observations give only a general idea of what Pluto's composition.
It appears that Pluto has a rocky core making up 50% to 70% of its mass. The rest (30%-50%) is thought to be a mantle of water ice. There is also a very thin outer layer of 98% solid nitrogen. Methane and carbon monoxide have also been detected.
What is below Pluto atmosphere?
Below Pluto's tenuous atmosphere is its icy surface, composed primarily of frozen nitrogen, methane, and carbon monoxide. This surface is covered in mountains, plains, and vast areas of frozen water ice. The dwarf planet also has a rocky core believed to contain metals and silicate rocks.
Is there anything special about Pluto?
Pluto is unique in our solar system as the only dwarf planet. It has a highly elliptical orbit that brings it closer to the Sun than Neptune at times. Pluto is also known for its large moon, Charon, which is so large in comparison that they orbit each other, creating a binary system.
No. Planet X was a proposed planet believed to orbit somewhere beyond Neptune based on an anomaly in the orbit of Uranus believed to be caused by the gravity of an unknown planet. Searches for planet X led to the discovery of Pluto, but later studies found that Pluto is not nearly massive enough to have caused the anomaly. It was later discovered that the apparent anomaly was due to a small miscalculation in the mass of Neptune.
State four requirements needed to be considered a planet?
To be considered a planet, an object must orbit the Sun, be spherical in shape due to its gravity, and have cleared its orbit of other debris. It should also not be a satellite of another object.
What are all outer planets except pluto known to be?
The outer planets of the solar system are Jupiter, Saturn, Uranus, and Neptune. Pluto was also included as an outer planet from the time it was discovered in 1930 until being reclassified as a dwarf planet in 2006.
Pluto was originally classified as the ninth planet in our solar system in 1930 but was reclassified as a dwarf planet by the International Astronomical Union in 2006. It has five known moons, with the largest moon, Charon, being about half the size of Pluto itself. Pluto's orbit is highly elliptical, meaning it is not a perfectly circular path around the Sun.
What is the average temperature on the surface of Pluto?
The average temperature on the surface of Pluto is around -375 degrees Fahrenheit (-225 degrees Celsius). Pluto is located very far from the sun, resulting in extremely cold temperatures on its surface.
Why Pluto is called a dwarf planet?
Pluto is considered a dwarf planet because it has not cleared its orbit of other debris, which is one of the criteria for being classified as a full planet. Additionally, its small size and location in the Kuiper Belt make it more similar to other objects in that region than to the eight recognized planets in our solar system.
What does the name Pluto mean?
Pluto is the name for the Greco-Roman god of the underworld. The name is Ancient Greek in origin meaning "wealthy one".
In astronomy Pluto was formerly considered the 9th planet in the solar system. Due to reclassification it is now considered to be a dwarf planet.
In astrology Pluto represents transformation, hidden motivations, the will, occult knowledge, mysteries of all types, power , destruction, sex, and death. In mundane astrology, the branch of astrology that deals with events of earth that affect humanity, it rules government and politics. It is considered to be the co-ruler of the zodiac sign Scorpio.
Compare the size of Pluto and Jupiter?
Jupiter is much larger than Pluto. Jupiter has a diameter over 11 times greater than that of Pluto and is significantly more massive. Pluto is considered a dwarf planet and is much smaller compared to Jupiter.
Does Pluto have a magnetic field?
No, Pluto does not have a global magnetic field. This is in contrast to planets like Earth, which do have magnetic fields generated by their cores. Without a global magnetic field, Pluto is not able to deflect solar winds or create auroras like planets with magnetic fields can.
What myths or legends does Pluto have?
Pluto's late discovery precludes a historic or folk tradition. Ancient peoples were unaware that it existed. The planet was named after the Roman god of the dead, the underworld, and the outer regions. Pluto was the son of Saturn, grandson of Uranus, and brother of Jupiter and Neptune. Mortals generally viewed him with dread.
What is the approximate period of revolution for Pluto?
A year on Pluto is 247.92 Earth years, or 90,553 Earth days, one day on Pluto is equivilant to 6.387 earth days, or 153.3 hours.
Are they going to blow up Pluto?

High Fructose Corn Syrup & Mercury
Independent TestingFound No Quantifiable Mercury -
Review by Duke University Medical Center
Woodhall Stopford, MD, MSPH, of Duke University Medical Center, one of the nation's leading experts in mercury contamination, reviewed the results of total mercury testing of samples of high fructose corn syrup conducted by Eurofins Central Analytical Laboratory (Metairie, LA) in February and March 2009. Dr. Stopford concluded:
- No quantifiable mercury was detected in any of the samples analyzed.
- High fructose corn syrup does not appear to be a measureable contributor to mercury in foods.
In his summary of findings, Dr. Stopford stated, "Mercury is ubiquitous in the environment being generated both by man-made activities (such as coal-fired power plants) and by natural phenomenon (such as volcanoes). Mercury is found naturally in all living things, including all categories of foods and beverages. Levels in foods and beverages have dropped significantly in the last 40 years. The introduction of high fructose corn syrup as a sweetener has not been associated with any noticeable difference in mercury levels in foods and beverages containing high fructose corn syrup. Levels of mercury found in such foods and beverages are what would be expected from mercury found normally in such foods and beverages and are at background levels."
To view Dr. Stopford's analysis and conclusions, please see: http://duketox.mc.duke.edu/HFCS%20test%20results4.doc.
Tests Find No Quantifiable Mercury Levels in High Fructose Corn SyrupWASHINGTON, DC - Manufacturers of high fructose corn syrup in the United States and Canada commissioned independent testing and expert review following a recent report alleging mercury findings in high fructose corn syrup. No quantifiable levels of mercury were found according to the independent lab Eurofins Central Analytical Laboratory, whose work and results were reviewed by Woodhall Stopford, MD, MSPH, of Duke University Medical Center, one of the nation's leading experts in mercury contamination.
"The American public can rest assured that high fructose corn syrup is safe. Safety is the highest priority for our industry, which is why we immediately commissioned external testing as well as independent expert review of claims concerning mercury and our corn sweetener. No quantifiable levels of mercury were found in high fructose corn syrup," said Audrae Erickson, president, Corn Refiners Association.

Expert Assessment: HFCS Mercury Study Flawed and MisleadingSAN FRANCISCO - ChemRisk, a leading scientific consulting firm, was asked by the Corn Refiners Association (CRA) to examine the recent publication by Institute for Agriculture and Trade Policy (IATP), "Not So Sweet: Missing Mercury and High Fructose Corn Syrup," and the Environmental Health journal publication "Mercury from chlor-alkali plants: measured concentrations in food product sugar," by Dufault et al, 2009, and to offer our comments and analysis.
In summary we found:
- The IATP report and Environmental Health article it references fall well below standards for proper scientific research and published literature.
- The authors of both publications provide incomplete data and misleading conclusions.
- Methods described by the authors deviate from standard procedure in testing for mercury.
- The authors ignore important distinctions between organic and other forms of mercury and their implications for assessing human health risk.
- Even if it were assumed that the mercury content found in the extremely limited sampling of foods and beverages was representative, the amounts are far lower than levels of concern set by government agencies.
- The authors assume that the total mercury they detected in a questionably small sampling of consumer foods is primarily the result of high fructose corn syrup; an assumption that has not been proerly tested or validated. The recipes for the items studied may have had multiple sources of potential contamination.

Pluto is classified as a dwarf planet within our solar system since it was reclassified from a full planet in 2006. It is located in the Kuiper Belt, a region of icy bodies beyond Neptune.
How many Plutos can fit in the Sun?
Approximately 1.3 million Earths could fit inside the Sun, so the number of Plutos that could fit inside the Sun would be significantly higher. To calculate the exact number of Plutos, the volume of Pluto would need to be compared to the volume of the Sun, taking into account their sizes.
How do you describe the surface of Pluto?
Scientists believe that the surface of Pluto is color Pink.
This is because Pluto's surface is very cold, it turned into pink
It has also been confirmed by Hubble Space Telescope.
Does seasonal temperatures exist on Pluto?
Yes, the seasons are caused by the elliptical nature of Pluto's orbit round the sun. In the summer period when Pluto is nearest the sun it develops an atmosphere which freezes out as it moves further away. At present (2008) Pluto has an atmosphere, it is 2/3 of its way through in its warm season and the probe launched to it has an objective of studying its atmosphere.
