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.
New Horizons was more than 203,000,000 km (126,000,000 mi) away from Pluto when it began taking the photos, which showed Pluto and its largest moon, Charon. On 20 March 2015, NASA invited the general public to suggest names for surface features that will be discovered on Pluto and Charon. [ 26 ]
Pluto's last passage through its perihelion was on 5 September 1989. [6] As of 2015, it is moving away from the Sun and its overall surface illumination is decreasing. However, the situation is complicated by its big axial tilt (122.5° [44]), which results in long polar days and nights on large parts of its surface.
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.
On October 15, 2015, it passed Pluto's orbit at a distance of 213 million kilometers (over 1 AU) distant from Pluto. [25] [26] This was four months after New Horizons' Pluto flyby. [27] In addition, two small yo-yo de-spin weights on wires were used to reduce the spin of the New Horizons probe prior to its release from the third-stage rocket ...
Simpler models from the early 2000s simulating how Pluto and Charon came to be in their current orientation supported the idea that some object collided with Pluto to create Charon.
For example, as the Earth's rotational velocity is 465 m/s at the equator, a rocket launched tangentially from the Earth's equator to the east requires an initial velocity of about 10.735 km/s relative to the moving surface at the point of launch to escape whereas a rocket launched tangentially from the Earth's equator to the west requires an ...
How could an exoplanet so far away be causing such a hubbub? Pluto's movement in Aquarius certainly is, at least in the astrological world. ... Pluto will then moving back to Capricorn from Sept ...
