Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, ... Pluto's origin and identity had long puzzled astronomers.
Pluto, discovered by Clyde Tombaugh in 1930, is an interesting target for planetary exploration, but Pluto presents significant challenges for exploration because of its small mass and great distance from Earth. In 1964, Gary Flandro of the Jet Propulsion Laboratory proposed a mission called Grand Tour, taking advantage of the fact that an ...
Types of distant minor planets. The Kuiper belt (/ ˈkaɪpər / KY-pər) [1] is a circumstellar disc in the outer Solar System, extending from the orbit of Neptune at 30 astronomical units (AU) to approximately 50 AU from the Sun. [2] It is similar to the asteroid belt, but is far larger—20 times as wide and 20–200 times as massive. [3][4 ...
On July 15, people all over the world watched a woman in a cubicle wait for a signal from three billion miles away. In a soft, clear voice, she confirmed that the New Horizons spacecraft had flown within 7,800 miles of Pluto and survived. In the following days, the spacecraft transmitted images that revealed for the first time what the surface ...

Starting 3.2 days before the closest approach, long-range imaging included the mapping of Pluto and Charon to 40 km (25 mi) resolution. This is half the rotation period of the Pluto–Charon system and allowed imaging of all sides of both bodies.
Space travel under constant acceleration is a hypothetical method of space travel that involves the use of a propulsion system that generates a constant acceleration rather than the short, impulsive thrusts produced by traditional chemical rockets. For the first half of the journey the propulsion system would constantly accelerate the ...
A simulated view of the Pluto–Charon system showing that Pluto orbits a point outside itself. Also visible is the mutual tidal locking between the two bodies. Charon and Pluto orbit each other every 6.387 days. The two objects are gravitationally locked to one another, so each keeps the same face towards the other. This is a case of mutual ...
