What is the Solar System?The collection of eight planets and their moons in orbit
around the sun, together with smaller bodies in the form
of asteroids, meteoroids, and comets. The 8 planets
are Mercury, Venus, Earth, Mars, Jupiter,
Saturn, Uranus and Neptune.
The Solar SystemAsteroids are rocky and metallic objects too
small to be considered planets. They are sometimes called minor planets.
A meteor is a bright streak of light in the sky (a "shooting star" or a "falling star").
Comets are small celestial bodies that orbit the Sun. They are primarily made of dust and ice.
The Sun
The sun is the star that our solar system revolves around.
The earth could fit into the sun 1.3 million times.
The sun is the largest object in the solar system.
It is mostly made up of hydrogen, the lightest gas ever found. Hydrogen has no color, no smell and no taste.
What is a moon?A moon is a body that circles a larger planet
or body. The natural satellite of the earth,
visible by reflected light from the sun.
What is a star?A Star is a big exploding balls of gas, mostly
hydrogen and helium. In simpler terms a star
can be defined as a ball of fire or gas.
What is a planet?Define as an object that orbits a star, is large
enough to have settled into a round shape
and, crucially, has cleared the neighborhood
around its orbit.
MercuryMercury is the planet that is closest to the
sun.Mercury does not have a moon.A day on Mercury is equal to 176 days on
Earth.The surface of Mercury is similar to that of
the Earth’s moon. It has many things like mountains, hills, lava plains, craters and valleys.
VenusVenus is the Second planet from the sun.A day on Venus is longer than a year on
earth.The Atmosphere is composed of Carbon
DioxideVenus has no moons.It is called Earth’s sister planet.
EarthIt is the third planet from the sun. The only planet that supports life in our Solar
System.Earth has 1 moon.71% of the Earth’s crust is covered with water.
MarsThis planet is fourth from the sun.Last of the terrestrial (earth-like) planets.Called the Red planet because of its color.Mars has 2 moons; Phobos and Deimos.
JupiterJupiter is the 5th planet from the sun and is
the largest planet in the Solar System.Jupiter has 61 known moons!!!
Saturn
Saturn is the 6th planet from the sun.Saturn is best known for its rings.The rings around Saturn are made up of
frozen gases, water ice and rock. So the rings are not solid bands around the planet.
There are 31 moons orbiting Saturn.
Uranus
Uranus is the 7th planet from the sun.Uranus has 21 moons.
NeptuneNeptune is the 8th planet from the sun.A year on Neptune is equal to over 164 years
on earth!!There are 11 known moons, Triton is the
largest!
Assessment
How many moon does earth have? Which is the ring planet?Which planet is known as Earth’s sister?The sun is a ____________, not a planet. Which planet is the largest? How many planet are there in the solar
system?
