Our Solar system is one of over 500 known solar systems in the entire
Milky Way galaxy the solar system came into being about 4.5 billion years ago
when a cloud of interstellar gas and dust collapsed resulting in a solar nebula
a swirling disk of material that collided to form the solar system the solar system
is located in the Milky Way's. Orion star cluster only 15% of stars in the
galaxy host planetary systems and one of those stars is our own Sun revolving
around the Sun are eight planets the planets are divided into two categories
based on their composition terrestrial and Jovian terrestrial planets including
Mercury Venus Earth and Mars are primarily made of rocky material their
surfaces are solid they don't have ring systems they have very few or no moons
and they are relatively small the smallest and closest to the Sun is mercury
which has the shortest orbit in the solar system at about 3 earth months. Venus
is the hottest planet with temperatures of up to 867 degrees Fahrenheit due to
an atmosphere of carbon dioxide and extensive lava flows next to this world of
fire is a world of water earth the water systems on this planet helped create
the only known environment in the universe capable of sustaining a life the
last of the terrestrial planets Mars might have also supported life about 3.7 billion
years ago when the planet had a watery surface and moist atmosphere beyond the
four terrestrial planets of the inner solar system lie the Jovian planets of
the outer solar system the Jovian planets include gas giants Jupiter and Saturn
and ice giants Uranus and Neptune the gas giants are predominantly made of
helium and hydrogen and the ice giants also contain rock eyes and a liquid
mixture of water methane and ammonia all four Jovian planets have multiple
moons sport ring systems have no solid surface and are immense the largest Jovian
is also the largest planet in the solar system Jupiter nearby is Saturn the
solar system's second largest planet its signature rings are wide enough to fit
between earth and the moon but are fairly a kilometer thick past Saturn are the
ice giants Uranus and Neptune the slightly bigger of these ice giants Uranus is
famous for rotating on its side next to Uranus is Neptune the outermost planet
in the solar system and also one of the coldest orbiting the terrestrial
planets is the asteroid belt a flat disc of rocky objects full of remnants from
the solar system's formation from microscopic dust particles to the largest
known object the dwarf planet Ceres another disk of space debris lies much
further out and orbits the Jovian planets the icy Kuiper belt apart from
asteroids the Kuiper belt is also home to dwarf planets such Pluto and is the
birthplace of many comets beyond the Kuiper belt is the Oost cloud a vast
spherical collection of icy debris it is considered the edge of the solar
system since that is where the gravitational and physical influences of the Sun
end our solar system's particular configuration of planets another celestial
objects all revolving around a life-giving star make it a special place to call
home
