What are some differences between Pluto and the gas planets?

Pluto is a dwarf planet located in the Kuiper Belt while gas planets (like Jupiter, Saturn) are made primarily of hydrogen and helium. Gas planets are much larger in size and have thick atmospheres, while Pluto is smaller and composed mostly of rock and ice. Additionally, gas planets have rings and numerous moons, whereas Pluto has only five moons and no rings.

Where was Pluto formed?

Pluto is a dwarf planet, as astronomers have found millions of Pluto like objects circling the sun in the kuiper belt, some are even bigger than Pluto like Eris. So they decided to call all these plutoids dwarf planets, instead of adding lots more planets to the solar system.

A dwarf planet has to be big enough to plough its way out of other objects like asteroids and its gravity has to be strong enough to hold it in a spherical shape.

Describe the motions of Charon relative to the horizon?

Charon is tidally locked with Pluto, meaning one side always faces the planet. As Pluto rotates, Charon's position relative to the horizon would change. Charon itself does not have its own rotation, so its position in the sky would remain consistent from Pluto's surface.

How is Pluto more like Quaoar and Sedna than it is like Neptune?

Pluto, Sedna, and Quaoar are all solid objects with icy surfaces and are small when compared to the planets of the solar system. Saturn is a giant planet primarily composed of hydrogen and helium. It does not have a solid surface.

Are there planets beyounde pluto?

Yes, there are many planets beyond Pluto in our solar system. These include dwarf planets like Eris, Haumea, and Makemake, as well as other trans-Neptunian objects in the Kuiper Belt and the scattered disk. Additionally, there may be a hypothetical ninth planet, often referred to as Planet Nine, located far beyond Pluto's orbit.

What was Pluto's power's the roman god?

Pluto, the Roman god of the underworld, had power over the dead souls and was responsible for judging and sentencing them. He also controlled the wealth of the earth, including precious metals and gems found underground. Additionally, Pluto was associated with the cycle of life, death, and rebirth.

How did scientists figure out that Pluto was not just another star?

Pluto was first discovered in 1930 by Clyde W. Tombaugh at the Lowell Observatory in Flagstaff Arizona. Astronomers had long predicted that there would be a ninth planet inthe Solar System, which they called Planet X. Only 22 at the time, Tombaugh was given the laborious task of comparing photographic plates. These were two images of a region of the sky, taken two weeks apart. Any moving object, like an asteroid, comet or planet, would appear to jump from one photograph to the next.

After a year of observations, Tombaugh finally discovered an object in the right orbit, and declared that he had discovered Planet X. Because they had discovered it, the Lowell team were allowed to name it. They settled on Pluto, a name suggested by an 11-year old school girl in Oxford, England (no, it wasn't named after the Disney character, but the Roman god of the underworld).

The Solar System now had 9 planets.

Astronomers weren't sure about Pluto's mass until the discovery of its largest Moon, Charon, in 1978. And by knowing its mass (0.0021 Earths), they could more accurately gauge its size. The most accurate measurement currently gives the size of Pluto at 2,400 km (1,500 miles) across. Although this is small, Mercury is only 4,880 km (3,032 miles) across. Pluto is tiny, but it was considered larger than anything else past the orbit of Neptune.

Over the last few decades, powerful new ground and space-based observatories have completely changed previous understanding of the outer Solar System. Instead of being the only planet in its region, like the rest of the Solar System, Pluto and its moons are now known to be just a large example of a collection of objects called the Kuiper Belt. This region extends from the orbit of Neptune out to 55 astronomical units (55 times the distance of the Earth to the Sun).

Astronomers estimate that there are at least 70,000 icy objects, with the same composition as Pluto, that measure 100 km across or more in the Kuiper Belt. And according to the new rules, Pluto is not a planet. It's just another Kuiper Belt object.

Is Pluto sometimes closer to the Sun than Neptune?

Yes, Pluto is closer to the Sun than Neptune for a ~20 year period every 228 years. The last time it was closer to the Sun than Neptune was 1979. This happens because Pluto has an eccentric orbit that is also highly inclined, Pluto's size\mass is not directly involved in this process in any way.

Did Clyde Tombaugh discover Pluto in Texas?

Clyde Tombaugh discovered Pluto at the Lowell Observatory in Flagstaff, Arizona.

When was Pluto qualifyed a dawrf planet?

Pluto was discovered in 1930 and originally called a planet. In 2006, Pluto was re-classified to be a dwarf planet due to the discovery of a number of similar rocky, icy bodies in the solar system. To avoid increasing the number of planets dramatically, Pluto and similar bodies were re-classified.

Is Pluto a planet or a dog?

Pluto is a dwarf planet located in our solar system. It was once considered the ninth planet but was reclassified as a dwarf planet in 2006. A dog named Pluto is a cartoon character created by Walt Disney.

Compare Pluto and the eight planets?

Pluto is located in what is know to be the Kuiper belt on the outside of our solar system. recently, scientists have discovered tens of thousands of other "planets" in this area, and many of them are as large or larger than Pluto Pluto has characteristics of a planet, like a moon, and an orbit, but because of its size and elliptical orbit, it is not a planet. It is actually the first member of a new category called dwarf planets. the newest dwarf planet is Eris which is slightly larger than Pluto.

What would happen if Pluto rammed into Neptune or one of its moons?

Pluto hitting one of Neptune's moons would probably destroy that moon, leaving a bunch of debris scattered in the area. Over time, that debris would probably collect into a new ring around Neptune.

If Pluto hit Neptune, Neptune wouldn't be destroyed. Neptune has 10,000 times the mass of Pluto. There would definitely be some effects on Neptune, probably spraying debris into orbit and creating a new ring or even moon of Neptune. Also, the weather patterns of Neptune would be quite changed, so we'd probably see a bunch of dark spots or other changes to the appearance of Neptune.

Which planet is not classified as a gas giant or a terrestrial planet?

Out of all the planets in our solar system, four are considered gas giants or Jovian planets. They are Saturn, Neptune, Uranus and Jupiter. The ones that are not gas giants are Mars, Mercury, Venus, and Earth.

Does Pluto have its own moon?

Yes, the dwarf planet Pluto has five moons down to a detection limit of about 1 km in diameter. In order of distance from Pluto, they are:

  1. Charon
  2. Styx
  3. Nix
  4. Kerberos
  5. Hydra

Charon, the largest of the five moons, is mutually tidally locked with Pluto, and is massive enough that Pluto-Charon is sometimes considered a double dwarf planet.

How many light years is Pluto's orbit?

Pluto's orbit is not measured in light years as it is within our solar system. Pluto's average distance from the Sun is about 3.7 billion miles or 39.5 astronomical units.

Why did scientists know about Ceres for so long before the other dwarf planets?

The answer to this question can be simplified because Ceres is much nearer than any other dwarf planet in our solar system.

Ceres is in the Asteroid Belt which lies between Mars and Jupiter

All the other known Dwarf Planets lie in the Kuyper Belt passed and beyond the reaches of Neptune's Orbit of the Sun.

Ceres was then (1801) under mathematical scrutiny as to it's very existence and it's orbit was then unknown.

Ceres is only 580 miles across but from earth would be much larger visually from a reasonable telescope than say Pluto or any other of the Dwarf planets in the Kuyper Belt.

Ceres is the first ever asteroid to be discovered

What does Eris orbit?

Eris is a dwarf planet located in the outer solar system. It orbits the Sun in a highly elliptical path, ranging from about 38 to 98 astronomical units (AU) away from the Sun. It takes Eris approximately 558 years to complete one orbit around the Sun.

What are the names of the dwaf planets?

there are 3 dwarf planets and their names are

Ceres

Pluto

Eris

( they were in order)

How many earth days are equal to 31 days on Pluto?

The sidereal rotation period of Pluto is about 6.39 Earth days.

Therefore, 31 Plutonian days is equal to (31 * 6.39) = 198.09 Earth days.

Also note that 31 Earth days would be equal to (31 / 6.39) = 4.85 Plutonian days.

How long to Pluto on a spacecraft?

On the Space Shuttle

The distance from Earth to Pluto is not constant, but averages to 3.57 billion miles. The Space Shuttle orbits at 17,500 miles per hour. Therefore 205,000 hours or 8,500 days or 23 years 105 days.

On the New Horizons probe

In January 2006, NASA launched the New Horizons probe on a mission to fly by Pluto. New Horizons is one of the fastest man-made objects ever launched, and is not scheduled to arrive at Pluto until July 2015 (it will not be entering orbit around Pluto. To do so it would have to slow down, significantly lengthening the travel time). So, as of now, it takes about 9.5 years to travel from the Earth to Pluto.

Why Neptune sometimes farther from the sun than Pluto?

Neptune is brighter than Pluto because it is larger and (usually) closer to earth. There isn't enough differences in the albedo or "reflectivity" of the two planets to offset Neptune's size advantage. Even when Pluto slides inside the orbit of Neptune, which the dwarf planet does during part of its orbit of the sun, its smaller size does not permit it to compete with Neptune for brightness.

No effence but i need more of an answer than this

The diameter of Pluto and Ceres and Eris?

2.9 AU or 257 million miles from the sun between the orbits of Mars and Jupiter. Or for astronomy it's to the bottom left of Aquarius (very close to the sun). It's orbit is fairly circular and takes 4.6 years to move along.
