When was Pluto disscovered not a planet?
It was not so much a discovery that Pluto wasn't a planet, so much as a general concensus that it shouldn't be called a planet anymore. Over the past decade, astronomers have discovered several bodies beyond the orbit of Pluto that are in fact larger (for example, Eris.) They realized that there were probably many more they hadn't discovered yet and that the term planet was impractical for Pluto since it was so small and there were so many similar sized objects orbiting the Solar System. Eris was probably the final blow to Pluto's status. It is larger than Pluto and for a long time astronomers called it the solar system's "tenth planet''. In the face of this discovery and the fact that many other similarly sized objects had been found, the International Astronomical Union decided to formally define the word "planet" for the first time in 2006 and in the process effectively demoted Pluto.
How do they know how far is a planet?
Within our solar system, it's really easy to tell each planet's distance from the sun.
From Newton's law of gravitation, we realized that the time it takes a planet to revolve around the sun only depends on the planet's distance from the sun, and if we know the distance of one of them, we can figure out all the others.
If we watch a planet move through the sky, we can see how long it takes for that one to revolve once around the sun. Then we need to know both the distance and time of one planet, and from that one we can calculate all the others.
The one for which we know both the distance from, and time to orbit, the sun, is ... our Earth ! With this information, plus watching another planet to see how long it takes to orbit the sun once, we can calculate how far it is from the sun.
Does the orbit of Pluto sometimes cross that of the planet Neptune?
Pluto has a highly elliptical orbit which is at a steep angle to the ecliptic.The ecliptic is the plane that contains the sun's apparent motion through the skies from earth's point of view. Pluto is a K.O. (Kuyper Object, an object from the Kuyper Belt, more like an icy comet than an asteroid). It does travel within the orbit of Neptune for a few years out of its long orbit, but never in a way that will bring it crashing down onto Neptune. Pluto is locked into a special harmonic relationship with Neptune which prevents that from happening. For every 2 orbits of Pluto there are 3 orbits of Neptune. They are never close enough to collide. Pluto spends the vast majority of its orbital time in the Kuyper Belt, beyond Neptune's orbit.
Why was Pluto removed from the planetary system?
Pluto does not follow the same orbit as all the other planets. That is to say it has a high eccentric orbit that does not follow the ecliptic. The ecliptic is an imaginary line taken from the Sun's equator and extended out across the solar system, like the rings of Saturn.
Pluto is small and probably a captured asteroid or Kuiper belt object(KBO ) and so was voted not to be an original planet formed at the birth of the solar system.
How much would an object weigh on earth if it weighed 100 ponds on Pluto?
An object that weighs 100 pounds on Pluto would weigh 262 pounds on Earth, assuming the same mass of the object. This is because weight is proportional to the gravitational force acting on an object, and the gravitational force is stronger on Earth than on Pluto.
What dwarf planet was considered an asteroid?
Ceres is a dwarf planet and it is registered in the minor planet center as asteroid number 1. However, it is a dwarf planet not an asteroid. Asteroids and comets are similar bodies that do not have hydrostatic equilibrium and are relatively small. Recent rulings by the International Astronomical Union (IAU) have reclassified it and justly so (though I personally don't believe dwarf planets and normal terrestrial planets are as different as they contend).
How long would it take to emancipate your self?
The process of emancipating oneself can vary depending on individual circumstances and legal requirements in the specific location. It typically involves demonstrating financial independence and the ability to make informed decisions, which can take several months to years. It is important to seek guidance from a legal professional familiar with emancipation laws in your area.

Pluto is considered a dwarf planet because?
It is considered a Dwarf Planet for many reasons. One reason why it is the a Dwarf is because it goes through the Kuiper Belt every time it rotates and as it rotates in the Kuiper Belt it gets hit!
How many earths can fit in vv cephei?
It is estimated that 2000000000 Earths could fit inside VV Cephei How do we know? It is known that one million Earths could fit inside the Sun, and VV Cephei is estimated at 2000 times bigger than the Sun.
Why do you weigh more on earth than on Pluto?
You weigh more on Earth than on Pluto because of the difference in gravitational pull between the two. Earth's gravitational force is much stronger than Pluto's, which causes you to weigh more on Earth.
Does Pluto orbit in the ecliptic plane?
No, Pluto's orbit is inclined relative to the ecliptic plane by about 17 degrees. This means that Pluto's path around the Sun is tilted compared to the orbits of the major planets in our solar system.
The Hydra was born from the blood of the monster Typhon when he was wounded by the god Hercules. It is a serpent-like creature with multiple heads that grow back when cut off, making it a formidable adversary in Greek mythology.
Are there people on the planet Pluto?
Very unlikely... The former planet or the Pipe Line Under The Ocean, a project that M.W Kellogg was working on for Uncle Sam. It was used during the Normandy Campaign for logistics. Just where the terminals were was and still is classified. the Astronomical-sounding name had everybody convinced it was something to do with space shots- but, it was the Pipe Line Under The Ocean! glug glug.
What planet is closest to Earth - Mars Neptune or Pluto?
Mars. Apart from the Moon and Venus, Mars is the closest celestial object to the Earth, it has been called Earth's 'twin' planet. Neptune and Saturn are both gas giants farther on out in the solar system.
What is the name of Pluto's counterpart?
Charon is considered Pluto's counterpart in Greek mythology as they were both figures in the underworld. Charon was the ferryman who transported souls across the River Styx to the underworld in Greek mythology, similar to how Pluto (Hades) ruled over the underworld.
What is 123.23 light years in earth years?
If you are asking how long it would take to travel the distance of 123.23 light years, then that would depend on how fast you are traveling. Because a light year is a measure of distance not time.
Is it worth wasting your life to go to Pluto?
That decision depends on your personal values and priorities. Consider the opportunity cost of spending your life on a journey to Pluto compared to other life experiences or goals you may have. Each individual will have their own perspective on what is considered "worth it."
No one currently lives on Pluto as it is a dwarf planet located in our solar system. It is far from Earth and extremely cold with no known atmosphere that could support human life. Any future exploration missions to Pluto would likely be performed by spacecraft rather than humans.
Do dwarf planets have gravity?
Yes, dwarf planets have gravity just like any other astronomical body. Gravity is a fundamental force that exists due to the mass of an object, so all objects with mass, including dwarf planets, have their own gravitational pull.
If it take sam take 3 minutes to read a page how long would it take her to read 605 pages?
It would take Sam 1,815 minutes to read 605 pages (3 minutes per page x 605 pages). This is equivalent to 30 hours and 15 minutes.
What is determined by the surface features of an area?
Surface features of an area can determine its topography, vegetation, drainage patterns, soil types, and usability for various activities such as farming, construction, or recreation. These features give the landscape its unique character and influence local climate and ecological processes.
Is Pluto the only dwarf planet that orbits the Sun?
As far as we can actually PROVE, it is the only dwarf planet that orbits our own Sun. However, there has long been some speculation that there may be another dwarf planet out beyond Pluto, that is even smaller, but which is too far away from the Sun to be seen with optical instruments. It has also been debated that some large meteorites that orbit the Sun between the orbits of the planets, should maybe be declared as being dwarf planets in their own right.
Plutonic rocks are intrusive rocks that feature magma that has cooled underground in chambers, or plutons. Plutonic has large crystals that are well formed. Gabbro and granite are included in the coarse-grained plutonic.
How long would it take to walk 12 miles?
The answer to this question depends on many things. First of all, different people walk at different speeds, but most people walk at a rate of between two and three miles every hour.
A slow walker (one travelling 2mph) would take almost 605 hours, or about 25 days. A fast walker (going 3mph) would make the same trip in 403 hours, or 17 days. So the simple answer is: "Probably between 17 and 25 days".
The problem with these calculations, though, is that in the above examples, our walkers never stopped to eat, rest, sleep or take bathroom breaks. These delays could add a lot of time to the trip. If our walker slept for 8 hours each day, and spent the rest of the time walking, the trip would take between 25 and 37 days, depending on walking speed. If the walker slept for 8 hours each day, but also spent three hours a day finding a place to sleep, buying food to eat on the go, and getting ready each morning, we are looking at 31 to 46 days.
Also, someone who is out of shape might have to rest more. If the walker is carrying a lot of supplies, they may travel more slowly. People also travel more slowly over rough or rocky terrain, or if they spend a lot of the time heading up hill. There are so many things that can affect the answer, that it is very difficult to calculate how long it would take to complete this journey.
Realistically, for most people, though, a journey of 1209 miles would probably take from 4 to 7 weeks. It isn't really possible to get more precise without a lot more information.
