	Solar System / Planets K-12 Experiments for Lesson Plans & Science Fair Projects
		Major features of the Solar System (not to scale): The Sun, the eight planets, the asteroid belt containing the dwarf planet Ceres, outermost there is the dwarf planet Pluto (the dwarf planet Eris not shown), and a comet.
		The inner solar system was too warm for volatile molecules like water and methane to condense, and so the planetesimals which formed there were relatively small (comprising only 0.6% the mass of the disc) and composed largely of compounds with high melting points, such as silicates and metals.
		The immediate galactic neighborhood of the solar system is known as the Local Fluff, an area of dense cloud in an otherwise sparse region known as the Local Bubble, an hourglass-shaped cavity in the interstellar medium roughly 300 light-years across.

		The principal component of the Solar System is the Sun, a main sequence G2 star that contains 99.86% of the system's known mass and dominates it gravitationally.
		The Solar System is believed to have formed according to the nebular hypothesis, first proposed in 1755 by Immanuel Kant and independently formulated by Pierre-Simon Laplace.
		The immediate galactic neighborhood of the Solar System is known as the Local Interstellar Cloud or Local Fluff, an area of dense cloud in an otherwise sparse region known as the Local Bubble, an hourglass-shaped cavity in the interstellar medium roughly 300 light-years across.

	Solar Energy Systems - Utah Geological Survey
		Solar Heating Systems: Heat for water, homes, and buildings can be provided by solar water and space heating systems, which utilize solar collectors to capture the sun's energy.
		A passive solar structure is one that permits direct sunlight to entering through windows to provide heating, but is also designed to not overheat the structure and to minimize heat loss through the windows at night.
		Features of passive solar design are structure shape and orientation, window area, thermal mass to store heat, overhangs to shade the windows in summer, and thermal shades or highly insulated windows.

		A generic solar system (or planetary system) consists of at least one star and various orbiting objects (such as asteroids, comets, moonss, and planets).
		Small quantities of dust are present throughout the solar system and are responsible for the phenomenon of zodiacal light.
		Planetary systems are generally believed to form as part of the same process which results in star formation; although, some argue that systems are formed by some kind of accidental "stellar near-collison".

	The Solar System and its Origins
		Inner Solar System bodies (including the belt asteroids) are rocky bodies, and quite small (none is bigger than the Earth), while the outer Solar System bodies are icy, where they are solid at all.
		Specifically, in the inner solar system, the Earth is fairly active geologically, the Moon and Mercury are dead worlds, and Mars and Venus are in between.
		Vulcanism is also ubiquitous in the inner solar system (and in the outer solar system as well)but among the inner planets, only the Earth and Venus probably still have active volcanos.

	Solar system (Site not responding. Last check: 2007-09-17)
		In broad terms, the solar system consists of the Sun, eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor planets, planetoids, meteoroids, planetesimals or, in the case of Pluto, planets).
		In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a results, the inner planets formed minerals and are rocky, and the outer planets were massive enough to attract gases.
		The solar system is part of the Milky Way galaxy, a spiral galaxy with a diameter of about 100,000 light years containing approximately 200 billion stars, of which our Sun is rather large and bright.

		In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a result, the inner planets are rocky and the outer planets were massive enough to capture large amounts of lighter gases, such as hydrogen and helium.
		The solar system is located in the Local Fluff of the Milky Way galaxy, a spiral galaxy with a diameter of about 100,000 light years containing approximately 200 billion stars, of which our Sun is rather large and bright.
		The total surface area of the solar system's objects that have solid surfaces and a diameter greater than 1 km is ~1.7 km2 andmdash;about 11 times the area of the Earth's land masses wherever possible.

	Revelations in the solar system
		Unfortunately, such discoveries are usually interpreted in terms of an age for the solar system of billions of years and as having come about by natural processes, without input from the hand of God.
		For instance, the Voyager missions in the 1970s and 80s revealed surprising features in the beautiful rings of Saturn, which were found to possess a very detailed structure, described as ‘rings within rings within rings.’ The sharp edges of the rings and other evidences imply that the rings must be quite young in age.
		This solar wind would have an effect of driving excess gas and dust out of the still forming solar system and thus there would no longer be enough of the light gases left to form Jupiter and the other three giant gas planets.

		The Solar System consists of a star (the Sun = 99.85% Mass of entire solar system) and planets, asteroids, and comets, which orbit it in a broad, flat disk.
		In this hypothesis, the Solar System was born from a cloud of interstellar gas that collapsed to a disk called the solar nebula.
		The flat shape of the system and the common direction of motion around the Sun arose because the planets condensed within the nebula's rotating disk.

	Solar System Forensics :: Astrobiology Magazine ::
		Scientists have long argued whether the chemical compounds created in the early solar system were produced with the help of the energy of the early sun or were formed by other means.
		They conclude in their paper that the slight excess of one isotope of sulfur, ³³S, in the meteorites indicated the presence of "photochemical reactions in the early solar nebula," meaning that the protosun was shining strongly enough to drive chemical reactions.
		Astronomers believe the solar nebula began to form about 5 billion years ago when a cloud of interstellar gas and dust was disturbed, possibly by the shock wave of a large exploding star, and collapsed under its own gravity.
