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.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
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.
Humanity's first object to attain Solar system's escape velocity. First probe to traverse the asteroid belt, to reach Jovanian system, to use a gravity assist and to leave the proximity of Solar systems' planets. Held the record for fastest human-made object at the time and the most distant one until Voyager 1 overtook in 1998.

NASA launched the New Horizon spacecraft in 2006 to learn more about the icy dwarf planet Pluto. Here are some of the first photos from that mission, taken from between 125 and 115 million miles away.
The decision to name the object Pluto was intended in part to honour Percival Lowell, as his initials made up the word's first two letters. [30] After discovering Pluto, Tombaugh continued to search the ecliptic for other distant objects. He found hundreds of variable stars and asteroids, as well as two comets, but no further planets.

When it comes to landmark achievements in space exploration, today will be a date for the history books as the day humanity reached Pluto for the first time. If everything goes according to plan ...
