An intense search conducted by New Horizons confirmed that no moons larger than 4.5 km in diameter exist out to distances up to 180,000 km from Pluto (6% of the stable region for prograde moons), assuming Charon-like albedoes of 0.38 (for smaller distances, this threshold is still smaller).
Pluto (bottom left) compared in size to the Earth and the Moon. Pluto's diameter is 2 376.6 ± 3.2 km [5] and its mass is (1.303 ± 0.003) × 10 22 kg, 17.7% that of the Moon (0.22% that of Earth). [125] Its surface area is 1.774 443 × 10 7 km 2, or just slightly bigger than Russia or Antarctica (particularly including the Antarctic sea ice ...
Authors and artists associated with space exploration, especially Pluto and the Kuiper Belt. Some features discovered by the New Horizons mission have been given provisional names based on various science fiction and fantasy franchises, including Star Wars , Star Trek , Doctor Who , Alien , Firefly , and Macross .

(Pluto has four smaller moons besides Charon.) For example, Mars is orbited by two tiny potato-shaped moons called Phobos and Deimos, which are likely two asteroids that were captured by the red ...
Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto's moon Charon, the largest moon orbiting any of our solar ...
The geography of Pluto refers to the study and mapping of physical features across the dwarf planet Pluto. On 14 July 2015, the New Horizons spacecraft became the first spacecraft to fly by Pluto. [ 1 ] [ 2 ] During its brief flyby, New Horizons made detailed geographical measurements and observations of Pluto and its moons .
Three-body capture, more recently proposed by C. B. Agnor and D. P. Hamilton in 2006, involves Triton in a binary system with a third object, similar to Pluto and its large moon Charon. In this hypothesis, as the binary system approaches Neptune, it becomes unbound by tidal forces; one component of the binary is ejected from the system, and ...
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.
