Slide Topic: Solar System
The Solar System[c] is the gravitationally bound system of the Sun and the
objects that orbit it. The largest of these objects are the eight planets, which in
order from the Sun are four terrestrial planets (Mercury, Venus, Earth and Mars);
two gas giants (Jupiter and Saturn); and two ice giants (Uranus and Neptune). The
Solar System developed 4.6 billion years ago, when a molecular cloud was
compressed, forming the Sun and a protoplanetary disc.
Mars is the fourth planet and the furthest terrestrial planet from the
Sun.
Mercury is the first planet from the Sun and the smallest in the Solar
System.
Venus is the second planet from the Sun. It is a rocky planet with the densest
atmosphere of all the rocky bodies in the Solar System
Earth is the third planet from the Sun and the only astronomical object
known to harbor life.
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
Many stars are much larger – but the Sun is far more massive than our home
planet: it would take more than 330,000 Earths to match the mass of the Sun, and
it would take 1.3 million Earths to fill the Sun's volume. The Sun is about 93
million miles (150 million kilometers) from Earth.
Our solar system has one star, eight planets, five officially recognized dwarf planets
at least 290 moons, more than 1.3 million asteroids, and about 3,900 comets.
It is located in an outer spiral arm of the Milky Way galaxy called the Orion Arm, or
Orion Spur. Our solar system orbits the center of the galaxy at about 515,000 mph
(828,000 kph). It takes about 230 million years to complete one orbit around the
galactic center
