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 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 .
Luna Linea is a dark linear feature (linea) on the dwarf planet Pluto. It was discovered by the New Horizons craft in July 2015 and named after the Luna program, a Soviet space exploration program that was the first to visit the Moon. The name was officially approved by the International Astronomical Union (IAU) on 11 April 2023. [1]
NASA has released the 'first and best' images the New Horizons spacecraft was able to take of Pluto during its flyby of the dwarf planet in July. This is what Pluto looks like, up close Skip to ...
Voyager Terra is a region on the dwarf planet Pluto, north of Viking Terra and Tombaugh Regio and west of Pioneer Terra, which was discovered in July 2015 by the New Horizons spacecraft. It is named for the Voyager program and Voyager 2 , the first spacecraft to explore Uranus and Neptune and to cross into interstellar space .
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.
Many TNOs are often just assumed to have Pluto's density of 2.0 g/cm 3, but it is just as likely that they have a comet-like density of only 0.5 g/cm 3. [ 4 ] For example, if a TNO is incorrectly assumed to have a mass of 3.59 × 10 20 kg based on a radius of 350 km with a density of 2 g/cm 3 but is later discovered to have a radius of only 175 ...
Pluto 350 aimed to send a spacecraft, weighing around 350 kilograms, to Pluto. [11] The spacecraft's minimalistic design was to allow it to travel faster and be more cost-effective, in contrast to most other big-budget projects NASA were developing at the time, such as Galileo and Cassini. Pluto 350, however, would later become controversial ...
