Dwarf Planet Pluto

Yes, a year is the time it takes a planet to complete one orbit around the sun. This is also known as the orbital period. Different planets have different orbital periods based on their distance from the sun.

Scientists know that stars have planets through various methods, including measuring the wobble of a star caused by a planet's gravitational pull, observing the dimming of a star's light as a planet passes in front of it (transit method), and direct imaging using powerful telescopes. These methods have helped identify thousands of exoplanets orbiting distant stars.

It's not possible to be on the sun due to its extreme temperatures, but if you mean how would age be calculated on the sun, you would not have an age in the same way as on Earth since time is not experienced in the same manner due to the sun's conditions.

The length of a "solar day" on Pluto is determined by its axial tilt.

The planet takes 6.38 Earth days to rotate, and 249 Earth years to go around the Sun. But the tilt (60 degrees to the plane of its orbit) produces exaggerated seasons with some polar areas of the planet spending many Earth years in either the constant dim sunlight or constant darkness.

Pluto does not clear its orbit of debris, a key criteria for planethood, as defined by the International Astronomical Union in 2006. Additionally, Pluto shares characteristics with other objects in the Kuiper Belt, suggesting it is more akin to a dwarf planet or large asteroid than a full-fledged planet.

The fact that Pluto has hydrostatic equilibrium (a roughly spherical shape caused by gravitational influence) as attested to via the Hubble images. One could argue that it is a double planet with Charon which also maintains hydrostatic equilibrium and is bigger than the dwarf planet Ceres. This reviewer happens to believe that the idea of a planet completely clearing it's orbit of debris as a prerequisite to be a planet is silly and in many cases involving lagrange points is impossible.

No, Pluto does not have humidity as it has a very thin atmosphere composed mostly of nitrogen, methane, and carbon monoxide. These gases do not create the conditions necessary for humidity to exist on Pluto.

The symbol for Charon, the largest moon of the dwarf planet Pluto, is a combination of the letters "C" and "H." The "C" stands for "Charon" and the "H" represents the shared first initial of Pluto's discoverer, Clyde W. Tombaugh.

Jupiter, Saturn, Uranus & Neptune are the four outer planets the four inner planets are Mercury, Venus, Earth, and Mars.

Year is the amount of time it takes the Earth to revolve around the sun. It takes Pluto about 250 years to complete one revolution about the sun.

In 1905, Percival Lowell predicted that a new planet, which he called "Planet X," would be found beyond Neptune. This prediction eventually led to the discovery of Pluto in 1930, though it was later reclassified as a dwarf planet.

Classical planets are the five planets visible to the naked eye from Earth: Mercury, Venus, Mars, Jupiter, and Saturn. They have been observed since ancient times and hold significance in various astrological and astronomical systems.

Kepler's third law of planetary motion, which states that the square of the orbital period of a planet is directly proportional to the cube of its semi-major axis or orbital radius. This relationship allows astronomers to predict the orbital periods of planets based on their distances from the sun.

In August 2006, the International Astronomical Union (IAU) redefined the criteria for what qualifies as a planet. Pluto did not meet these updated criteria and was therefore reclassified as a "dwarf planet" rather than a full-fledged planet.

Yes, there are moons that do not orbit planets but instead orbit other celestial bodies like asteroids or dwarf planets. For example, some moons of dwarf planets in the Kuiper Belt do not orbit a planet.

Pluto, Eris, Ceres, Haumea and Makemake are the dwarf planets found so far. As you can see there are 5 now, not just 4.

Yes, NASA's New Horizons spacecraft conducted a historic flyby of Pluto on July 14, 2015, capturing the most detailed images of the dwarf planet to date. It provided valuable data and insights into Pluto's geology and atmosphere.

Comet tails are made up primarily of dust, rock, and gas expelled from the comet as it is heated by the Sun. The frozen gases expand and throw off material, some of which is blown by the solar wind into a "tail" for the comet.

(The tail is always pointing away from the Sun.)

It thickness or thinness is measured by the molecular weight and the surface pressure. The average molecular weight is about 28 and the pressure is 15 lb/sq.in. That can be compared with atmospheres on other planets e.g. Venus, Mars and all the outer planets.

Pluto was reclassified from a planet to a dwarf planet in 2006 by the International Astronomical Union because it did not meet all three criteria needed to be classified as a planet. One of those criteria is that a planet must have cleared its orbit of other debris, and Pluto shares its orbit with other objects in the Kuiper Belt.

One unusual aspect of Pluto's moon is that it is nearly half the size of Pluto itself, making it one of the largest moons relative to its planet in the solar system. Additionally, its orbit is highly elliptical and tilted, unlike most other moons that orbit closer to their planet's equator.

Aidoneus, Aides (meaning, like Hades, the unseen), Pluto (the rich one), Ditis Pater, Dis Pater, Dis(all meaning the rich one), Orcus (killer), Polydectes (the receiver of many), Clymenus (the Illustrious), Eubulus (the giver of good counsel), etc. He is the "one of many names".

Celestial bodies that orbit around a planet are called moons or natural satellites. Moons can vary in size and composition, and they usually orbit their parent planet due to gravitational forces. Some planets have multiple moons, such as Jupiter and Saturn, while others have none, like Venus and Mercury.

It takes light approximately 5.5 hours to travel from the Sun to Pluto, which is about 4.67 billion miles away at its farthest point. The time it takes for a beam of light to reach Pluto depends on its distance from Earth at any given time.

Pluto has been classified as a dwarf planet in the Solar System since 2006. This reclassification was made by the International Astronomical Union (IAU).
