Pluto is mostly brown. This picture captures the true colors of Pluto as well as the highest surface resolution so far recovered. No spacecraft has yet visited this most distant dwarf planet in our Solar System. The above map was created by tracking brightness changes from Earth of Pluto during times when it was being partially eclipsed by its moon Charon. The map therefore shows the hemisphere of Pluto that faces Charon. Pluto's brown color is thought dominated by frozen methane deposits metamorphosed by faint but energetic sunlight. The dark band below Pluto's equator is seen to have rather complex coloring, however, indicating that some unknown mechanisms may have affected Pluto's surface
have a question regarding the order of the planets, rocky planets in the inner solar system followed by the gaseous planets. Then there's the rocky planetoids. Do you think they formed in that order or is it more likely that they formed in the inner ss and then flung out to the outer ss?
"Another factor in the development of the four inner terrestrial planets and the outer gaseous planets was temperature. After the protoplanets had formed, the central regions of the solar nebula were collapsing and forming the Sun, as described in Module 2. The young Sun caused the temperature of the closer inner protoplanets to be higher than the outer protoplanets. As a result, the kinetic energy of the gaseous molecules was too high for them to coalesce, and they simply dissipated. At the outer planets, however, the molecules were cold, and were moving slowly enough for gravity to overcome their movement. Over the course of several million years, the planets grew into the planets we know today. "
