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 do some scientists think that Charon isn't a moon of Pluto?
Charon does not truly orbit Pluto. Rather, Charon's gravity moves Pluto enough that both objects orbit around their common center of mass, which is outside of Pluto. This led to suggestions that the Pluto-Charon system be classified as a binary or double planet.
Was Pluto been blown up yet or is not going to be blown up?
No. If Pluto was ever blown up it would make breakignews everywhere and chunks of it would hit the Earth and kill us all. ==D----------------------
Why would your 1996 Mercury Villager's power steering seem not to have any power?
You probably have an air lock in the pump. You need to take the pump apart and assenble the veins with vasoline so it will prime itself. GoodluckJoe
Is a white dwarf smaller than Pluto?
A white dwarf could be smaller or bigger than the moon since it's size varies depending on the mass of the white dwarf.
Since the mass of the moon is 7.347 x 1022 kg and the mass of Pluto is 1.31×1022 kg the size of a white dwarf is also smaller or bigger than Pluto depending on it's mass.
How does the diameter of Pluto compare to that of Earth?
It covers more distance and ground than Earth
What is the comet belt outside of Pluto's orbit called?
There are some comets near Pluto, amongst the bodies in the "Kuiper Belt".
However, I think the answer to this question is the "Oort cloud" of comets, far beyond the orbit of Pluto.
Why would you take nootropics?
In 1964, scientists at the Belgian pharmaceutical company UCB synthesised a substance now known as Piracetam. Dr. Corneliu E. Giurgea, who led the team that synthesized Piracetam, coined the new substance a "Nootropic" and later branded the product Nootropil. The scientists were amazed at the safety of Piracetam, even in large doses. They observed the ability of Piracetam to increase mental functioning both in healthy people and in individuals with diseased mental conditions, such as Alzheimer's and dementia. Dr. Giurgea came up with a set of criteria that substances had to meet in order to be considered a true nootropic.
- The substance enhances learning and memory
- The substance enhances learned behaviours under conditions which are known to
- disrupt them (hypoxia, for example)
- The substance protects the brain from chemical or physical injury
- The substance enhances the tonic cortical/subcortical control mechanisms
- The substance exhibits few side effects and extremely low toxicity, while also lacking
- the pharmacology of typical psychotropic drugs (motor stimulation, sedation, etc.)
Piracetam met all of these criteria and was subsequently the first substance labeled as a nootropic. Soon, many other compounds were derived from this new family of drugs called Racetams. From Piracetam, other Racetams such as Oxiracetam, Aniracetam, and Pramiracetam were developed and touted to be even more potent than the previous derivative. While each of the Racetams provide differing solubilities and potencies, they vary little in their effects. No one has been able to identify the exact mechanism of how Piracetam positively influences memory, but it is generally accepted that it enhances cerebral blood flow and protects brain cells from damage from oxygen deprivation. It is also said to increase communication between the left and right hemispheres of the brain through stimulation of the corpus callosum. In terms of safety, Piracetam has little, if any, side effects. One scientist said that it was safer than salt and described the potential side effects as "few, mild, and transient."
Is Pluto the furthest away planet in your solar system?
No, because Pluto is not a planet. Pluto was formerly considered the farthest planet in the solar system until it was demoted in 2006. Now the title goes to Neptune.
Pluto is the only planet in the solar system that has not been explored with a spacecraft. What is know about the dark, frozen world is the result of many years of work by scientists. It is thought that Pluto is made up of a mixture of rocks and several kinds of "ices". Scientists believe that most of the ices that make up Pluto are frozen methane and ammonia.
The rotation of Pluto is inclined approximately 119.5 degrees to it plane of orbit
What kind of scientist would study Pluto has a highly unusual orbit compared to Mars or earth?
Geologist
Is very little known about Pluto's surface condition?
That is correct. Pluto is so very far away that we can't see it well on a telescope to see what the ground looks like.
What is the speed of light from Pluto to earth?
A rough average of the distance between Earth and Pluto = 3,667,000,000 miles
That's a difficult question to answer precisely. Pluto's average distance from the Sun is 39.4 AU. (An AU is an Astronomical Unit and is defined as the average distance between the center of the Earth and the center of the Sun.) One AU equals 92,955,807 million miles, or about 93 million miles, but Pluto's distance from the Sun ranges from 29.7 to 49.3 AU. So, depending on the orbits of Pluto and Earth, the distance between the two could be anywhere from 28.7 AU (Earth directly between Pluto and Sun when Pluto is closest to the Sun) to 50.3 AU (Earth directly opposite Sun from Pluto when Pluto is farthest from the Sun). However, keep in mind that an AU is an average and that Earth's actual orbit varies anywhere from 91 to 94.5 million miles.
How big is Hydra Pluto's moon?
They think its diameter is between 61 and 167 kilometers. It's hard to get an accurate measurement because it is so small and so far away.
What were Creon and the messenger doing when they prayed to Hecate and the Pluto?
Creon and the messenger prayed to Hecate and Pluto to be merciful to the spirit of the dead Polyneice. They bathed the body and then burned it.
How long would it take to reach Pluto in a car?
Assuming a car could travel through space at a constant speed of 60 mph (96.5 km/h) without any stops, it would take over 7,000 years to reach Pluto, which is about 3.67 billion miles (5.9 billion km) away from Earth on average. This calculation does not take into consideration the need for fuel, life support systems, or the lack of a road to drive on in space.
Where was Pluto disqualified in space?
Pluto was not disqualified in space. It was reclassed into a more specific category: dwarf planet.
Is Pluto the farthest from Earth?
No. Beyond Pluto, there are thousands of other objects orbiting the Sun.
Has Pluto ever completed 1 orbit around the sun?
Yes, many times. It takes it 248 years to go around the Sun, and while it was not discovered until 1930, it has been there for millions of years.
Why does Pluto's moon charon orbit around the earth instead of Pluto?
It doesn't. Charon is much too far away to be influenced by Earth's gravity. Charon is gravitationally bound to Pluto, but technically does not orbit it. Because Charon is fairly massive compared to Pluto the two object orbit around their common center of mass, which lies outside of Pluto.
What are the risks of traveling to Pluto?
as of 2017 we do not have the technology to travel to Pluto, so the risks would only be theoretical. Some risks might be:
- radiation exposure
- accidents and/or collisions en route
- systems failures
- finding people willing to sit in a tiny ship for nearly a decade of the their lives, and again on the way back
What is the difference between a terrestrial planet and a gas giant?
Each of the four inner planets have a clearly defined terrain. They are different to the gas planets, which don't have a clear solid surface. The inner planets are also much smaller and less massive, yet have a higher density than the outer planets. The inner planets have fewr moons due to their smaller mass and size. As they are closer to the sun, they orbit the sun in less time and are also warmer.
