Dwarf Planet Pluto

In our solar system, neither Mercury nor Venus have any moons.

For the 300+ extra-solar planets which orbit other stars, we have no way of detecting if the planets have any moons, although it is probable that many do. We're at the edge of our technology just detecting the planet.

In theory, an infinite amount of planets have no moons.

A planet must be large enough for its gravity to pull it into a nearly round shape. In our solar system, a planet needs to have cleared its orbit of other debris to be considered a true planet.

Pluto is located in the Kuiper Belt, a region of the outer solar system beyond Neptune. It is considered a dwarf planet and is one of the largest objects in this region. Pluto's orbit is highly elliptical, and it occasionally comes closer to the sun than Neptune.

The Kuiper Belt is a region of icy bodies beyond Neptune's orbit, containing dwarf planets such as Pluto and Eris. The Oort Cloud is a hypothetical region of icy bodies surrounding the solar system, extending much farther out than the Kuiper Belt and is the source of long-period comets.

Pluto is located outside of the asteroid belt. It is a dwarf planet that resides in the Kuiper Belt, a region of the outer solar system beyond Neptune where many icy bodies and other dwarf planets are found.

Water ice has been detected on Pluto's surface, primarily in the form of ices like methane and nitrogen, as its surface is too cold for liquid water to exist. However, recent studies suggest that there may be a subsurface ocean on Pluto, similar to those found on some other icy moons in the outer solar system.

It takes Mars 687.0 days to make one orbit around the sun (or 1.88 times for every one earth year).

Pluto's gravity is relatively weak compared to the gravity of larger planets like Earth. The gravitational pull on Pluto's surface is about 6% that of Earth's gravity. This means that a person who weighs 100 pounds on Earth would weigh only about 6 pounds on Pluto.

Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union because it did not meet all the criteria set for a planet. Specifically, it has not cleared its orbit of other debris and is part of the Kuiper Belt.

It took NASA's New Horizons spacecraft about 9.5 years to reach Pluto since its launch in January 2006. New Horizons completed its closest flyby of Pluto in July 2015, providing valuable data and imagery of the dwarf planet.

Pluto is not larger than any planet it is the smallest planet that why it is call a dwarf planet.

Pluto and asteroids are both celestial bodies that orbit the Sun. However, while Pluto is considered a dwarf planet and is part of the Kuiper Belt, asteroids are rocky objects mostly found in the asteroid belt between Mars and Jupiter.

Pluto's classification was changed from a planet to a dwarf planet in 2006 by the International Astronomical Union because it did not meet all the criteria to be considered a planet, specifically it has not cleared its orbit of other objects in its path. This reclassification was based on new understanding and definition of what constitutes a planet in our solar system.

Saturn is considered a hot planet because of its internal heat generated by processes like gravitational compression and radioactive decay. However, its distance from the Sun means that its surface temperatures are colder compared to terrestrial planets like Earth.

The temperature on Pluto varies greatly, ranging from about -375°F (-225°C) to -400°F (-240°C). This extreme cold is due to its distance from the sun, as well as its thin atmosphere which cannot retain heat well.

The Earth's moon is approximately 1/6 the size of Earth, making it the largest moon relative to its planet size in the solar system. Some scientists refer to the Earth-Moon system as a binary planet system due to the similar size and gravitational influence between the two bodies.

NASA's New Horizons mission aimed to study Pluto and its moons. Launched in 2006, it provided the first detailed images of Pluto and valuable data on its geology, atmosphere, and composition. The mission helped scientists better understand this distant and intriguing world.

A team of researchers from Southwest Research Institute (SwRI) in Boulder, Colo., The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., the Space Telescope Science Institute in Baltimore and Lowell Observatory in Flagstaff, Ariz., used Hubble Space Telescope images to make the discovery in support of NASA's New Horizons mission to Pluto and the Kuiper Belt beyond.

Pluto is an ancient Greek god, a cartoon dog, and a dwarf planet.

It's not a unit of length, and can't be converted to inches or centimeters.

The cost to visit the Himalayas can vary widely depending on factors such as transportation, accommodation, permits, and activities chosen. A rough estimate would be anywhere from $1,000 to $5,000 or more for a basic trip, excluding gear and other personal expenses. It's recommended to research and plan your trip thoroughly to get a more accurate budget.

Walter's head measures around 24 inches in circumference.

There are two main similarities between Mercury and Pluto. One is their smaller sizes, although Pluto is far smaller than Mercury. The other is their extreme distance from the sun. So Mercury is the closest known planet to the sun while Pluto was considered the furthest.

The seven moons that are larger than Pluto are Ganymede (Jupiter), Titan (Saturn), Callisto (Jupiter), Io (Jupiter), Earth's Moon (Earth), Europa (Jupiter), and Triton (Neptune).

Saturn is the least dense planet because it is primarily made up of hydrogen and helium, which are the two lightest elements. These elements have low densities compared to the rocky materials that make up the inner planets like Earth. Additionally, Saturn's large size and low mass contribute to its overall low density.

From Wikipedia:

"The Moon's distance varies each month between approximately 357,000 kilometers (222,000 mi) and 406,000 km (252,000 mi) due to its elliptical orbit around the Earth(distances given are center-to-center).[3][4][5]

The size and brightness of an object follows an inverse-square law, which means that a full moon at perigee is 12% larger and 30% brighter than an average full moon. However, because the offset of the moon's orbit versus its phases is only two days, this change in appearance is gradual from month to month and therefore is not usually noticeable to a casual observer."
