In 1941, Glenn T. Seaborg named the newly created element plutonium after Pluto, in keeping with the tradition of naming elements after newly discovered planets, following uranium, which was named after Uranus, and neptunium, which was named after Neptune.
He discovered Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt. At the time of discovery, Pluto was considered the ninth planet, but was reclassified as a dwarf planet in 2006. Tombaugh also discovered many asteroids, and called for the serious scientific research of unidentified flying objects.
On 20 March 2015, NASA invited the general public to suggest names for surface features that will be discovered on Pluto and Charon. [26] On 15 April 2015, Pluto was imaged showing a possible polar cap. [27] Between April and June 2015, New Horizons began returning images of Pluto that exceeded the quality that the Hubble Space Telescope could ...
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 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 ...
NASA's New Horizons probe has returned the first color images of Pluto. The small blurry dots in the newly-released photo are Pluto and Charon, the largest of Pluto's moons. New Horizons captured ...
Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.
Tombaugh Regio (/ ˈ t ɒ m b aʊ ˈ r ɛ dʒ i oʊ /), sometimes nicknamed "Pluto's heart" after its shape, [2] is the largest bright surface feature of the dwarf planet Pluto. [ 3 ] [ 4 ] [ 5 ] It lies just north of Pluto's equator, to the northeast of Belton Regio and to the northwest of Safronov Regio , which are both dark features. [ 6 ]
