What’s in Our Solar System?
•Our solar system consists of a central star (the Sun),
planets, dwarf planets, moons, asteroids, comets,
meteors, interplanetary gas, dust, and all the “space” in
between.
•Except for Earth, the planets of the solar system are
named for Greek and Roman gods and goddesses.

The Sun in solar system
 The Scientific name is Sol.
 The Sun is the largest object in our solar
system.
 Sun is a 4.5 billion-year-old star.
 The Sun is about 93 million miles (150
million kilometers) from Earth.
 It contains about 98% of all the rocks, dust,
and gas in the Solar System.

The Planets.
 There are more planets than stars in our galaxy. The
current count orbiting our star: eight.
 The inner, rocky planets are Mercury, Venus, Earth, and Mars.
 The outer planets are gas giants Jupiter and Saturn and
ice giants Uranus and Neptune.
 Every planet has its own path of movement which is known as
orbit.

The Earth.
 Is the only planet known to support life!
 Has a surface composed of 71% water.
Water is necessary for life on Earth.
 Is the basis for the Astronomical Unit
(distance from sun to Earth = 1 AU)
It has one natural satellite, the Moon, the
only large satellite of a terrestrial planet in
the Solar System.

Move ments of earth.
Earth's rotation or Earth's spin is the rotation of planet Earth around its
own axis, as well as changes in the orientation of the rotation axis in space.

Day and Night.
The Earth orbits the sun once every 365 days and rotates about its
axis once every 24 hours. Day and night are due to the Earth rotating
on its axis

The Earth’s satellite : The Moon
 The Moon is Earth’s only natural
satellite and the fifth largest moon in
the solar system.
 The Moon’s presence helps stabilize
our planet’s wobble and moderate our
climate.
 The Moon’s distance from Earth is
about 240,000 miles (385,000km).

Mercury
 Has a revolution period of 88 days.
 Has 1000° temperature swings from
day to night because there is no
atmosphere to trap heat.
 Is about 1/3 of Earth’s size
 Is about 1/3 Earth’s distance from the
sun (0.39 AU)

 Has retrograde rotation – so the sun rises in the
west and sets in the east!
 Reaches 900F at the surface due to a strong
greenhouse effect.
 Venus has no moons and takes 225 days to
complete an orbit.
 Is about the same size as Earth
 Is about 2/3 Earth’s distance from the sun (0.72
AU)

 Mars appears red because of iron
oxide, or rust, in its soil.
 Mars has two moons and takes about
two years to complete an orbit.
 Is about ½ of Earth’s size
 Is about 1 ½ times as far from the sun
as Earth (1.52 AU)

A comet is an icy, small Solar System
body that, when passing close to the
Sun, warms and begins to release
gases, a process that is called
outgassing.
Halley's Comet or Comet Halley, is
a short-period comet visible
from Earth every 76 years.

 Asteroids are small, rocky objects
that orbit the Sun.
Although asteroids orbit the Sun like
planets, they are much smaller than
planets.
 They probably consist of clay and
silicate rocks, and are dark in
appearance. They are among the most
ancient objects in the solar system.
