Pluto is a very excellent place to visit, for those who are adventurous,
curious, and hungry for discovery. Very little is known about the tiny
planet that is so far from Earth and Sun. Scientists of Earth have more
questions than they do have answers. Some are not even totally certain Pluto
is a planet!
Pluto is described as frozen, cold and dark. These are very strong
descriptions that sound like the Underworld, which was the place of death for
Romans. The god of the Underworld was named Pluto. Up-close Pluto is
yellowish-brown. Pluto is definitely the smallest "planet" of our solar
system. It is two-thirds the size of Earth's moon. Pluto has the diameter
of only 1,430 miles, which is smaller than any other planet by greater than a
factor of two. Pluto has a rotating time of 6 days and 9 hours, and it takes
248 Earth years to orbit. It is presumed to be composed of rock and ice,
like most outer planet satellites and asteroids. Pluto tilts 17.1 degrees
from the ecliptic. The ecliptic is the normal plane of orbit that most
planets have, including Earth. Pluto has a very thin atmosphere that
consists of nitrogen, carbon monoxide, and methane. Most of the time, Pluto
is the ninth planet from the sun, the farthest from the sun in our solar
system. This occurs for 228 years. After 228 years, during a twenty-year
period, Pluto switches places with Neptune. With this strange occurrence,
you might fear for a collision between Pluto and Neptune; but even in their
closest position with each other, they are more than 1 billion miles apart
from each other. Usually one is higher or lower than the other is, because
of their very different orbits. Nevertheless, Pluto probably has collided
with something before. With the discovery of Pluto in 1978, its moon was
discovered. It's composition and atmosphere causes others to hypothesize
that it is just a chunk of Pluto that separated from it after a collision.
This moon is called Charon. It is a satellite that is larger in proportion
to other satellites and the planets they orbit around in the entire solar
system.
Why do people question its status as a planet or not? Pluto is the only
outer planet that is small and solid like an asteroid or its own big moon.
This completely contrasts with the outer solar system ideal, because the
other outer planets are mostly gas and the largest of all the solar system.
Pluto is entirely too small in comparison to other planets, and some
satellites that circle Jupiter, Saturn, and Neptune. Pluto is believed to
have wandered in from outside of our solar system. Pluto's wild and strange
orbit creates questioning of its label. Pluto has been labeled a planet and
a Trans-Neptunian Object (TNO). Forget about UFOs. Instead, keep your eyes
peeled for TNOs, on our adventurous quest.
