Pluto is the smallest planet in the solar system. It is frozen whole and contains mostly permanently frozen ice. Other substances on Pluto include methane ice, nitrogen ice, ammonia ice as well as a tiny fraction of frozen carbon monoxide. Pluto is actually so cold (-387F) that its atmosphere freezes when Pluto is farthest away from the sun, equivalent to winter on earth.
Pluto is not well mapped and little about its geography is known. Whether Pluto has a magnetic field is unknown. Pluto is well-known for its moon, Charon. They are made up of the same chemical compositions and are roughly the same size, with Pluto less than twice as big as Charon. Moreover, they orbit synchronously (around each other while orbiting the sun). Pluto is tilted to its side and seems to have a collision of some sort with another space object. Charon is believed to be a chip off Pluto.
Geography:
Pluto is so cold that its atmosphere freezes when Pluto is farthest away from the sun (aphelion), which is winter on the Plutonian calendar. The frozen atmosphere seals up the planet’s surface. Its atmosphere is a gas at its perihelion
Pluto’s atmosphere is so thin and instable that it escapes into space, into Pluto’s moon, Charon, at times
Pluto is not well mapped and little about its geography is being known.
Anatomy:
As scientists continued their search for the planet affecting Neptune’s orbit, they found Pluto, but they concluded that it was too small to affect their orbits by gravity. Planet X (number 10) is still not found
Pluto rotates oddly. Its equator is right-angled that of its orbital plane, which means that its axis is parallel to its orbital plane
Pluto’s orbit is highly eccentric. Its aphelion has a high difference as that of its perihelion such that it is closer to the sun than Neptune at times
Pluto rotates in a retrograde motion
Pluto is the smallest planet in the solar system.
Pluto orbits in a ratio of 3 is to 2 resonance as that of Neptune. They will never collide due to exchanges of positions and velocities of angular momentum at their heliocentric orbits due to their tangential velocities, at different positions at different orbital periods of both planets
Resonance: A relationship in which the orbital period of one body is related to that of another by a simple integer fraction
Tangential velocities: Velocities which make two objects contact at a single point or along a line; touching but not intersecting.
Heliocentric orbits: Orbits as a reference system based on the center of the sun.
Chemical composition:
Pluto consists mainly permanently frozen ice
Other substances on Pluto include methane ice, nitrogen ice, ammonia ice as well as frozen carbon monoxide.
Pluto has similar chemical compositions and orbital statistics as Triton. Scientists believe that they were connected in the past. Pluto was captured by Neptune to its present orbit (unlike its past independent orbit) whileTriton went into the Oort Cloud.
Whether Pluto has a magnetic field is unknown.
Shape:A sphere
Climate:
Pluto’s surface temperature stands at –220 degree Celsius
Its has a thin atmosphere
Water exists as ice on Pluto
There is no apparent weather forces e.g. basic wind, at work on Pluto
Moons: 1
Charon (believed to a chip off Pluto due to a massive collision)
Charon is more than half the size of Pluto. It is actually a ball of ice with an icy surface. The substances found on Charon are the same as that of Pluto. Whether Charon has a magnetic field and an atmosphere is unknown. With Pluto tilted on its side, Charon is believed to be a chip off Pluto. An interesting fact is that Pluto and Charon actually orbit each other while orbiting the sun.
