Dwarf Planet Pluto

It is still known as Pluto, even though it was downgraded to a dwarf planet and given a number.

So really we should call it 134340Pluto.

Pluto is not the last planet technically. Now it is a dwarf planet as it became to small to be considered a planet. Pluto is not the last planet. It is called the last planet as it is the furthest away planet that orbits our sun. There are many other planets further away from us than Pluto.

You can find information on the distance from the Sun to Pluto on various websites such as NASA's Solar System Exploration website, the Jet Propulsion Laboratory's website, or on reputable astronomy websites like Space.com or EarthSky.

The dwarf planet Pluto was discovered on February 18, 1930. It was discovered by an astronomer named Clyde Tombaugh who was working at the Lowell Observatory in Arizona at the time. William H. Pickerin contributed to Pluto being found.

What is unusual is that Charon is the largest satellite relative to its planet in the solar system. And that Charon is more than half the size of Pluto.

Actually the Charon/Pluto system might be better termed a binary system as the two rotate about a common center of gravity (their "barycenter" which does not lie inside either body but in space between them.

Pluto has three known moons as of 2009. Charon is relatively large at 1,206 km in diameter (about half the diameter of Pluto), and was discovered in 1978 by Jim Christy. The other two, Hydra and Nix, were discovered in 2005 by a team using the Hubble Space Telescope. Hydra and Nix are estimated to be about 50 to 150 km in diameter, with Nix probably the smaller of the two.

The distance between Pluto and Mercury can vary greatly due to their elliptical orbits, but on average it is about 601 million kilometers.

The Kuiper belt extends from Neptune'sorbit to three billion kilometers beyond it. It contains lumps of icy material with organic compounds. That makes them like comets. These lumps are called Kuiper belt objects or minor planets. The Kuiper belt may have formed when the gravity of the young Jupiter sent the Kuiper belt objects out to where they are now.

Mercury orbits the Sun at from .31 AU to .46 AU (46 to 69 million kilometers). Pluto orbits the sun at from 30 AU to 49 AU. (4400 to 7400 million kilometers). So both have a considerably elliptical orbit, but generally speaking Pluto is about 100 times as far from the Sun as Mercury.

Pluto's largest moon is named Charon. It was discovered in 1978 by astronomer James Christy. Charon is about half the size of Pluto and they are tidally locked, meaning they always show the same face to each other.

Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because its small size and eccentric orbit do not meet the criteria to be considered a full planet in our solar system. Its classification was revised to better reflect its characteristics and align with new definitions of what constitutes a planet.

It's currently near the constellation Sagittarius. During the spring it will be in the sky in the morning, in the summer will be up all night, in the fall it will be up in the evening, and during the winter, it will only be up during the day. However, you will need a pretty good telescope to see it, Pluto's quite faint.

Pluto is composed primarily of ice and rock, with a thin atmosphere made up of nitrogen, methane, and carbon monoxide. It has a rocky core surrounded by a mantle of water ice and a surface covered in frozen nitrogen and methane. Pluto's composition is similar to that of other dwarf planets in the Kuiper Belt, where it resides.

A conceptual model represents abstract ideas and relationships, providing a high-level overview without specific implementation details. In contrast, a physical model represents the concrete implementation of a system, including specific elements, attributes, and relationships at a detailed level.

Pluto was relegated to "Dwarf Planet" status in 2006, but irrespective of planetary status, it is still a body orbiting our sun. Pluto (Dwarf planet) is about 5,913 million km from the sun (on average).

Earth is about 150 million km from the sun.

Venus is about 108 million km from the sun.

Mercury is about 58 million km from the sun. Depending on your definition of a planet, Pluto is easily the furthest but, if you insist that Pluto is no longer a planet, then it must be Earth.

Probably silicates and water ice. Its highly-reflective surface of methane ice initially suggested a much larger planet. But at 1/455th of the mass of Earth and 1/150th the volume, Pluto should not possess a large core of heavier elements.

Pluto is the smallest planet in our solar system, with a diameter of about 1,473 miles (2,371 kilometers), making it smaller than Earth's moon and smaller than all the other planets.

No. Pluto is still perfectly intact. It is no longer considered a planet as of 2006 because of a new definition, which Pluto did not quite meet.

Quite the contrary, Pluto is the slowest to orbit the sun. Each of the nine planets and their orbits in earth days and years are listed below:

Mercury - 87.96 days

Venus - 224.68 days

Earth - 365.26 days

Mars - 686.98 days

Jupiter - 11.862 years

Saturn - 29.456 years

Uranus - 84.07 years

Neptune - 164.81 years

Pluto - 247.7 years

Saturn's atmosphere is mostly composed of hydrogen and helium, with traces of methane, ammonia, and other gases. The upper layers are dominated by high-speed winds, reaching speeds of up to 1,800 km/h (1,100 mph). The thick atmosphere gives Saturn its distinct yellow-brown color.

Dwarf Planet, Pluto is closest to the Sun. At its farthest orbital point, Pluto is 4.67 billion miles or 40.7 AU (astronomical Units) away from earth. When they are closest together, they are 2.66 billion miles or 28.64 AU apart.

Pluto's thin atmosphere does contain some amount of ionized gas, or plasma, but not on the same scale as planets with more substantial atmospheres like Earth. The solar wind compresses and interacts with Pluto's atmosphere, creating regions of ionized gases.

The maximum temperature on Pluto is estimated to be around -375 degrees Fahrenheit (-225 degrees Celsius). This extreme cold is due to its distance from the Sun and its thin atmosphere, which is unable to retain heat effectively.

Some astronomers believe in the existence of another planet beyond Pluto, often referred to as Planet Nine, because of the unusual patterns observed in the orbits of distant objects in the Kuiper Belt. These patterns suggest that the gravitational influence of a massive, undiscovered planet could be at play. Further observations and simulations are ongoing to search for evidence of this hypothetical planet.
