Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is less massive than Eris.
Between then and around 1851, when the number of planets had reached 23, astronomers started using the word asteroid (from Greek, meaning 'star-like' or 'star-shaped') for the smaller bodies and began to distinguish them as minor planets rather than major planets. [5] With the discovery of Pluto in 1930, most astronomers considered the Solar ...
[6] [a] Charon and Pluto are also tidally locked, so that they always present the same face toward each other. The IAU General Assembly in August 2006 considered a proposal that Pluto and Charon be reclassified as a double planet, but the proposal was abandoned. [7] Like Pluto, Charon is a perfect sphere to within measurement uncertainty. [8]
For decades, astronomers have tried to determine how Pluto acquired its unusually large moon Charon, which is about half the size of the dwarf planet. Now, new research suggests that Pluto and ...
The geology of Pluto consists of the characteristics of the surface, crust, and interior of Pluto. Because of Pluto's distance from Earth, in-depth study from Earth is difficult. Many details about Pluto remained unknown until 14 July 2015, when New Horizons flew through the Pluto system and began transmitting data back to Earth. [1]
Clyde William Tombaugh (/ ˈ t ɒ m b aʊ /; February 4, 1906 – January 17, 1997) was an American astronomer.He discovered Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt.
If you were born before the '90s you probably know that Pluto, besides the much discussed dwarf planet that we are all so crazy about these days, is also a Disney animated dog.
As Pluto, the planet of growth, and evolution, moves into the sign of Aquarius, astrologers are bracing themselves for individual change and change on a global scale.
