The semi-major axis of Pluto's orbit varies between about 39.3 and 39.6 AU with a period of about 19,951 years, corresponding to an orbital period varying between 246 and 249 years. The semi-major axis and period are presently getting longer.
A Pluto orbiter/lander/sample return mission was proposed in 2003. The plan included a twelve-year trip from Earth to Pluto, mapping from orbit, multiple landings, a warm water probe, and possible in situ propellant production for another twelve-year trip back to Earth with samples. Power and propulsion would come from the bimodal MITEE nuclear ...
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 .
Pluto belongs to a group of objects that distantly orbit the sun called the Kuiper Belt, where thousands of icy remnants left over from the formation of the solar system linger. Eight of the 10 ...
It was used to integrate out to 845 million years – some 20% of the age of the Solar System. In 1988, Sussman and Wisdom found data using the Orrery that revealed that Pluto's orbit shows signs of chaos, due in part to its peculiar resonance with Neptune. [9] If Pluto's orbit is chaotic, then technically the whole Solar System is chaotic.
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 ...
The second full orbit of Neptune around the Sun since its discovery in 1846. 2177 "First Plutonian anniversary" of Pluto's discovery, given its orbit is just under 248 Earth years. 2178 January 28 2182 September 24 With an estimated probability of 0.04%, asteroid 101955 Bennu could hit Earth. 2185 Triple conjunction Mars–Saturn [56] 2186 July 16
