The universe and solar system

> Our solar system consists of an average star we call the Sun, the planets Mercury,
Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.

> It includes: the satellites of the planets; numerous comets, asteroids, and
meteoroids; and the interplanetary medium.

> The Sun is the richest source of electromagnetic energy (mostly in the form of heat
and light) in the solar system.

> The nine major planets including our earth and their moons are revolving around the
Sun.

The Terrestrial Planets


• The terrestrial planets are the four innermost
planets in the solar system, Mercury, Venus,
Earth and Mars. They are called terrestrial
because they have a compact, rocky surface like
the Earth's. The planets, Venus, Earth, and Mars
have significant atmospheres while Mercury has
almost none.

The Jovian Planets


• Jupiter, Saturn, Uranus, and Neptune are known
as the Jovian (Jupiter-like) planets, because they
are all gigantic compared with Earth, and they
have a gaseous nature like Jupiter's
• Satellites or Moons: are those celestial bodies, each of which are
revolving around any of these nine planets.
• Asteroids are the minor planets generally situated between orbits of Mars and
Jupiter.
• Comets are the heavenly bodies having along tail pointing approximately away from
the sun and a brighter head section (coma) that contains a small bright nucleus.
• Meteors are smaller solid bodies moving through the space, and getting illuminated
while entering earth’s atmosphere.
