It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium.&lt;/p&gt;</summary><content type="html">&lt;p&gt;The &lt;strong&gt;Solar System&lt;/strong&gt; is the &lt;a href="https://en.wikipedia.org/wiki/Gravity" title="Gravity"&gt;gravitationally&lt;/a&gt; bound system comprising the &lt;a href="https://en.wikipedia.org/wiki/Sun" title="Sun"&gt;Sun&lt;/a&gt; and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the &lt;a href="https://en.wikipedia.org/wiki/Planet" title="Planet"&gt;planets&lt;/a&gt;, with the remainder being significantly smaller objects, such as &lt;a href="https://en.wikipedia.org/wiki/Dwarf_planet" title="Dwarf planet"&gt;dwarf planets&lt;/a&gt; and &lt;a href="https://en.wikipedia.org/wiki/Small_Solar_System_body" title="Small Solar System body"&gt;small Solar System bodies&lt;/a&gt;. Of the objects that orbit the Sun indirectly, the &lt;a href="https://en.wikipedia.org/wiki/Natural_satellite" title="Natural satellite"&gt;moons&lt;/a&gt;, two are larger than the smallest planet, &lt;a href="https://en.wikipedia.org/wiki/Mercury_(planet)" title="Mercury (planet)"&gt;Mercury&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;The Solar System &lt;a href="https://en.wikipedia.org/wiki/Formation_and_evolution_of_the_Solar_System" title="Formation and evolution of the Solar System"&gt;formed 4.6 billion years ago&lt;/a&gt; from the &lt;a href="https://en.wikipedia.org/wiki/Gravitational_collapse" title="Gravitational collapse"&gt;gravitational collapse&lt;/a&gt; of a giant interstellar &lt;a href="https://en.wikipedia.org/wiki/Molecular_cloud" title="Molecular cloud"&gt;molecular cloud&lt;/a&gt;. The vast majority of the system's &lt;a href="https://en.wikipedia.org/wiki/Mass" title="Mass"&gt;mass&lt;/a&gt; is in the Sun, with most of the remaining mass contained in &lt;a href="https://en.wikipedia.org/wiki/Jupiter" title="Jupiter"&gt;Jupiter&lt;/a&gt;. The four smaller inner planets, &lt;a href="https://en.wikipedia.org/wiki/Mercury_(planet)" title="Mercury (planet)"&gt;Mercury&lt;/a&gt;, &lt;a href="https://en.wikipedia.org/wiki/Venus" title="Venus"&gt;Venus&lt;/a&gt;, &lt;a href="https://en.wikipedia.org/wiki/Earth" title="Earth"&gt;Earth&lt;/a&gt; and &lt;a href="https://en.wikipedia.org/wiki/Mars" title="Mars"&gt;Mars&lt;/a&gt;, are &lt;a href="https://en.wikipedia.org/wiki/Terrestrial_planet" title="Terrestrial planet"&gt;terrestrial planets&lt;/a&gt;, being primarily composed of rock and metal. The four outer planets are &lt;a href="https://en.wikipedia.org/wiki/Giant_planet" title="Giant planet"&gt;giant planets&lt;/a&gt;, being substantially more massive than the terrestrials. The two largest, Jupiter and &lt;a href="https://en.wikipedia.org/wiki/Saturn" title="Saturn"&gt;Saturn&lt;/a&gt;, are &lt;a href="https://en.wikipedia.org/wiki/Gas_giant" title="Gas giant"&gt;gas giants&lt;/a&gt;, being composed mainly of &lt;a href="https://en.wikipedia.org/wiki/Hydrogen" title="Hydrogen"&gt;hydrogen&lt;/a&gt; and &lt;a href="https://en.wikipedia.org/wiki/Helium" title="Helium"&gt;helium&lt;/a&gt;; the two outermost planets, &lt;a href="https://en.wikipedia.org/wiki/Uranus" title="Uranus"&gt;Uranus&lt;/a&gt; and &lt;a href="https://en.wikipedia.org/wiki/Neptune" title="Neptune"&gt;Neptune&lt;/a&gt;, are &lt;a href="https://en.wikipedia.org/wiki/Ice_giant" title="Ice giant"&gt;ice giants&lt;/a&gt;, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called &lt;a href="https://en.wikipedia.org/wiki/Volatiles" title="Volatiles"&gt;volatiles&lt;/a&gt;, such as water, &lt;a href="https://en.wikipedia.org/wiki/Ammonia" title="Ammonia"&gt;ammonia&lt;/a&gt; and &lt;a href="https://en.wikipedia.org/wiki/Methane" title="Methane"&gt;methane&lt;/a&gt;. All planets have almost circular orbits that lie within a nearly flat disc called the &lt;a href="https://en.wikipedia.org/wiki/Ecliptic" title="Ecliptic"&gt;ecliptic&lt;/a&gt;.&lt;/p&gt;
