What might be the effect of sprinkling black soot over the ice in the Arctic and Antarctica?
This would alter the snow-albedo feedback. Darkening the surface of snow/ice greatly lowers the albedo (reflectivity) of the surface. This would cause the snow/ice surface to absorb more solar radiation by virtue of its lower albedo, which would allow it to heat up more. Normally most solar radiation is simply reflected by snow back into the atmosphere and mostly out to space, so by causing it to absorb more you are heating up the lower atmosphere. By doing this, you are more likely to melt the snow/ice, whereby the albedo will be even lower, which would then absorb more radiation, etc.. This is called a positive feedback loop.
Which planet is believed by astronomers might be the core of what used to be a much larger planet?
The dwarf planet Pluto is believed by astronomers might be the core of a much larger planet
Why might it change that Neptune isn't the farthest planet from the sun?
Neptune is always the farthest planet from the Sun. But the dwarf planet Pluto will eventually grow in size as it continues to orbit and collect and grow from floating materials in space (e.g. smaller meteors landing and collecting on Pluto increase it's size). It isn't a planet now but could eventually grow to the size of a planet and regain its planetary status, making Neptune not the farthest from the sun.

What is the percentage of solar radiation reflected from a surface?
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
Mars has an albedo magnitude of?
The albedo of Mars is .15; you can see the albedo of all of the planets and moons in the solar system at the Nine Planets web site, linked below. "Albedo" is a measure of how reflective a body is. The higher the number, the more reflective the surface. So a high albedo says that a planet or asteroid reflects most of the light that hits it, while a low albedo indicates that most of the light is absorbed. Albedo can make calculations about climate change difficult. A planet with a high albedo reflects much of the Sun's light and heat, causing it not to heat up as much. A low albedo means that all of the solar radiation is absorbed and turned into heat. A warmer world will have less snow and ice cover, and thus a lower albedo, resulting in higher temperatures. On the other hand, a warmer world might have more clouds, which would increase Earth's albedo, reflect more sunlight, and reduce the heating effect. However, clouds also act to trap heat, sort of like a blanket. Whether the albedo effect would offset the "blanket" effect of clouds would depend on the type and height of the clouds and where they are located. Cloud effects are among the most important sources of uncertainty in modeling future climate change.

Which planet are you?
I might not be a planet . .
Are there any factors other than albedo that might affect temperature differences between the two setting?
Insufficient data.
Which planet is believed by astronomers might be the core of what used to be a much larger planet?
The dwarf planet Pluto is believed by astronomers might be the core of a much larger planet
Can planets form on another planet?
No, it might form from another planet but definitely not on another planet.
Did humans arrive on asteroids?
No, but it might possibly be theorized that the materials required to spark life on planet Earth could have been delivered in this way. Comets and meteors are also possibilities of the same effect.

Why is Ceres a planet now?
Ceres is not yet determined as a planet, just like Pluto it might not be a regular planet.
Are comets lighter than moon?
Do you mean lighter in color? Halley's comet has an albedo of about 0.04, which is the color of tar. Our Moon has an albedo of about 0.07, which is the color of weathered asphalt. If you mean lighter as in less massive... we've never seen a comet as massive as our Moon, but there are some pretty tiny moons out there in the outer solar system; a few comets might be larger than some of them.
