How did Pluto start being called the dwarf planet?
they decided to call it a dwarf planet because originaly it was called a planet, but then they had some kind of 'planet test' and unluckely pluto did not pass the size test, and was counted to small and was called the dwarf planet.
Why is Pluto sometimes eclipsed by Charon when seen from Earth?
Pluto and its moon Charon are tidally locked, which means they always show the same face to each other. When Pluto and Charon orbit around their common center of mass, sometimes Charon passes in front of Pluto from our line of sight, causing an eclipse. This alignment occurs due to their relative positions and orbital motions.
How long is the human backbone?
It depends on how tall the person is. The spinal column varies widely depending on a person's height (specifically how long the person's torso is).
Why are polar bears struggling to survive in the desert?
A desert is not good for a polar bear because it can't help it live. For example polar bears eat fish and other animals so if they lived in the desert it would be most likely that they wouldn't be able to find food and soon enough they would be extinct. Hope I helped :)
ANS2:That question presumes that polar bears don't do just fine in a desert...The frozen wastelands of the north are a form of desert because they have little liquid precipitation and plant life is scarce. Polar bears aren't found in any large numbers in other habitats.The interview contains run-on sentences and "filler" words while the preface uses complete sentences.
Who was the first person to explore Texas?
For Spain, the marooned conquistador Alvar Cabeza De Vacaexplored the Gulf of Mexico and Texas beginning in 1528. The exploration of the US Southwest came under the expedition of Francisco Coronado from 1540 to 1542.
In eastern Texas, the Gulf Coast was later explored by the French explorer Robert de La Salle in an ill-fated 1684 expedition down the Misissippi River (the explorer was killed by mutineers on this voyage).
If you compare it to Earth and Earth is 1 for mass, Pluto is 0.002.

How long does it take for earth to spin on its axis?
Just over 23 hours, 56 minutes and 4 seconds (86164.09054 seconds).
It takes almost 24 hours for the Earth to rotate once. But during this time, the Earth has moved slightly in its orbit, which is why it has to spin more (a full 24 hours) to get back to the same position facing the Sun (a "solar day")

The mean solar day, that is the average time it takes for the Sun to go from its highest point on a given day to its highest point the next day, is 24 hours. If you measure the time it takes a distant star to reach its highest point (the sidereal day), it is 86,164.091 seconds (or: 23 hours, 56 minutes, 4.091 seconds). The difference is the apparent motion of the Sun, which is really caused by the Earth moving around it . Take those 4 minutes a day, each day for a year, and it adds up to one "extra" day, or spin.
The period of Earth's spin (rotation) is just over 23 hours, 56 minutes and 4 seconds (86164.09054 seconds). (This is called the "sidereal day.")
The reason that it takes 24 hours for a place on Earth to be exactly facing the Sun again is that the Earth is moving in its orbit around the Sun at the same time. So it has to spin a bit more to get back to directly facing the Sun.

It takes the earth roughly 24 hours to spin on its axis.
24 hours
It takes 3minutes 56seconds less than 24hours for the Earth to spin (rotate) once on it's axis.
It takes 365.2422days for the Earth to revolve once around the Sun.
One completer spin takes 23hours 56minutes 4seconds. (rounded)
What is the size comparison of Earth and Pluto?
If Pluto's orbit were on the same plane as Earth's orbit, if Earth were directly between the sun and Pluto, if Earth were at its aphelion (the point in its orbit where it's farthest from the sun), and if Pluto were at its perihelion (the point in its orbit closest to the sun), on the scale where the diameter of Earth is 5 mm, the distance from Earth to Pluto is about 1.681 km (a little over a mile).
Why is planet earth considered as a blue planet?
I think that the Earth looks blue from outer space by an astronomer's eye is because the Earth is 75% water and 25% land. Since water is blue and there is a great quantity of it on the Earth, you spot the blue area first.
Why did francium take so long to discover?
Francium is a natural chemical element but the total quantity of francium in the earth crust is only approx. 30 g. Francium has ca. 40 isotopes and isomers but only two are natural: 221Fr (in the neptunium decay chain series) and 223Fr (in the actinium decay chain series). Artificially preparation of francium isotopes is also extremely difficult and expensive; and the chemistry and physics of isotopes was developed essentially after 1940. Supplementary, the most stable isotope of francium has a half life of only 21,8 minutes and is strongly radioactive; the half lives of the artificially prepared isotopes are more smaller.
This is sufficient reason to explain why francium was later discovered and why even today is only slightly studied.
Pluto has a tilted orbit (compared with the average plane of the orbits of the other planets).
Also, Pluto would be considered a "terrestrial planet", but it is not now defined as a planet. It's just called a "dwarf planet" now.
How did basketball circulate around the world?
The first big basketball players name was Stephon Veransloff, a German. Im not sure but i think he was about 7ft tall. He and some friends got together and started playing every other day, and it turned into a tournament every year. They brought it to North America and then it very big there about in the early 1900's. That is what I've heard.
AnswerDr. James created basketball during the wenter of 1981 because he needed a relyable game that the students can play during wenterPluto the Disney character relationship status: Dinah_the_Dachshundreplaced Fifi the Peke as Pluto's girlfriend.
Pluto the god relationship status: Pluto didn't have a girlfriend- he was married to the goddess Proserpine. Her Greek name was Persephone.
He's also known as Hades
God of the Underworld and Death
Dont believe that it was created between 0 years and above. Nobody actually knows when it was created because of all the things that happend on earth. For example if we dont know the exact year that dinousars became on earth we will not know how earth was before or atleast not know the exact year that the event occured.
Why does Pluto differ from the outer planets?
Pluto has a solid surface of rock and ice. It does not have a vast gaseous atmosphere.
The four smaller planets closer to the Sun are basically solid or rocky objects, while the four largest planets are all gas giants with deep, dense, swirling atmospheres. Pluto's solid surface, onthe other hand, more closely resembles that of the small, dense planets.
The four outer planets; Jupiter, Saturn, Uranus and Neptune; are all enormous planets largely made of gas and liquid. They travel round the Sun in nearly-circular orbits, widely spaced out. They all have rings and a system of many moons, and while asteroids and comets cross their orbits they are by far the biggest thing in their orbital zone.
Pluto, on the other hand, is tiny: smaller than our Moon. It is made up of a mixture of rock and ice, and has a solid surface you can stand upon. Its orbit is highly elliptical, tilted from that of the other outer planets, and it crosses the orbit of Neptune. It has a thin atmosphere, four moons, and no rings. Moreover, Pluto shares its orbit with thousands of other bodies ranging in size from "dirty snowballs" a few kilometres in diameter up to Eris, an object the size of Pluto itself. This region where Pluto orbits is now called the Kuiper Belt. Because Pluto is so different from the other outer planets and is instead more like the objects in the Kuiper Belt, Pluto was reclassified from a planet to a Kuiper Belt object in 2006. Some astronomers, however, continue to hold that Pluto should be called a planet.
Is Jupiter a planet or a dwarf-planet?
No. Jupiter is not a dwarf planet. Pluto, Ceres, Eris, Makemake, Hauma are dwarf planets.
What features have been found on Pluto?
I have deleted my previous answer to this one as I regret to say that I was badly wrong. A NASA probe called New Horizons was launched to explore Pluto in 2005 and arrived 10 years later, in 2015. It has shown that the planet is larger than was previously thought, about 2/3rds the size of our own moon, and has an interesting combination of cliffs, craters and huge canyons, as well as a frozen Polar ice-cap made up of frozen nitrogen and methane. It also sports a strange red spot in the shape of a heart.
Pluto has been downgraded to the status of a Dwarf Planet, as it does not dominate it's region of space as larger planets do. It has five moons- Charon, Hydra, Nix, Styx and Kerberos. The New Horizons probe has sent images of Pluto back to Earth, which can be looked up on the internet-as well as containing a number of sophisticated scientific instruments it also contains the cremated ashes of Clyde Tombaugh, the astronomer who discovered Pluto in 1930.
