Why do scientists believe there might be water on the Moon?
That description could fit any number of bodies in the solar system, but generally "asteroid" might be closest. Other more distant objects such as comets or Kuiper Belt Objects would tend to be more icy than rocky.

An applied scientists who studies the sun might ask how the energy is used in life. They may ask just how a plant is able to use the sun's energy to make food.
Like other members or the Kuiper belt Pluto is composed of a mixture of rock and various ices. It also orbits among other Kuiper Belt objects and is in orbital resonance with Neptune.
When the scientist is trying to represent an object or a system.
The five physical properties used to describe an object are color, shape, size, texture, and density. These properties can provide information about the appearance, dimensions, feel, and weight of an object.
Color, shape, texture, size, and density.
No and never was. There was an earlier hypothesis that it might have been a moon of Neptune, but this rejected due to the distance from Neptune. It is more than likely that Pluto is just a large Kuiper belt object.

The mass of an object does not change , but its weight can vary.
There are various reasons. Here are some:They might be skeptical of the reliability or truth of what other scientists have claimed.They might be trying to understand the earlier results better.They might be hoping to extend the other scientist's results.They might be trying to determine whether there are limits to the applicability of the other scientist's results.
A scientist might use a model as a research method for a few reasons. This model could tell the scientist how something moves for example.
there might not be enough proof
Well, that's pretty straightforward. An "object" is a named thing with certain properties, like in Plato's "Allegory of the Cave," and "classification" refers to a GROUP of similar things, that all share certain properties. To use a non-programming example, the classification "animals" might include objects like "mammal," "reptile," "bird," and so forth. Or those things might themselves be "classes," depending on your own personal choices and needs. So a "bird" might be a "class" including "objects" like "robin," "thrush," and "starling," with properties like "color of breast," "forked tail," and "temperament."
Gravitational interactions between passing objects always has the potential to disturb the orbits of the two bodies involved, but I'm unaware of any research indicating that objects have been observed to have been perturbed OUTWARD from the Kuiper Belt to the far more distant (and hypothetical) Oort Cloud. It has probably happened, at least a FEW times. But the Kuiper Belt itself is so distant that our ability to detect comet-sized objects is quite limited. And aside from the philosophical argument of "Where do new comets come from, if not from the Oort cloud?", we have precisely ZERO actual evidence that the Oort Cloud exists as postulated. There have been intermittent speculations that a massive but dark object, perhaps a planet or a brown dwarf star, might be in a highly elliptical orbit around the Sun. This object, occasionally named "Nemesis", might perturb distant Oort Cloud and Kuiper Belt objects out of their lazy orbits and drop them into the inner solar system as comets. The idea is that this might explain some strange periodicity of mass extinctions on Earth, that we might expect at any century a withering cosmic hailstorm of deadly proportion. But the proposed math and timetables never seems to work out, and a massive enough object should have been discovered by now.
