The document defines key terms in our solar system such as planets, moons, asteroids, comets, and stars. It provides details about the 8 planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune - including their distances from the sun, characteristics, and number of moons. It notes that the sun is at the center of our solar system and is made up mostly of hydrogen. It concludes with assessment questions to test the reader's understanding.

2. 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.

3. The Solar System
Asteroids 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.

4. 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.

5. 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.

6. 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.

7. 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.

8. Mercury
Mercury 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.

9. Venus
Venus is the Second planet from the sun.
A day on Venus is longer than a year on earth.
The Atmosphere is composed of Carbon Dioxide
Venus has no moons.
It is called Earth’s sister planet.

10. Earth
It 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.

11. Mars
This 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.

12. Jupiter
Jupiter is the 5th
planet from the sun and is the largest
planet in the Solar System.
Jupiter has 61 known moons!!!

13. 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.

14. Uranus
Uranus is the 7th
planet from the sun.
Uranus has 21 moons.

15. Neptune
Neptune 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!

16. 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?
