What do you think you know about the solar
system?
What do you want to know?
There are nine planets in our
Solar System:
Mercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, Neptune and Pluto
They all orbit around the Sun, the only star located in
our solar system
The Earth is the third planet from the Sun
Mercury, Venus, and Earth

Mercury
Mercury is the closest planet to the sun
Mercury hardly has any air in it’s atmosphere
Because of how slowly it rotates on it’s axis, it has days as hot as 870
degrees F and as cold as -370 degrees F
Mercury does not have any moons
Venus
Venus is the 2nd planet away from the sun and has a heavy cloud covering
its surface
It is the same size as Earth but has no moons
Has active volcanoes, “venusquakes”, as well as mountains and valleys
Earth
Earth is the third planet from the sun
It is the only known planet that has the atmosphere and temperature to
support human life
It has one moon
Mars, Jupiter, and Saturn

Mars
Mars is the fourth planet from the sun and has two moons
It has a climate more like earths with potential water as well as
mountains, valleys, and canyons
If you weighed 70lbs on Earth, you would weigh 27lbs on Mars
Jupiter
Jupiter is the 5th planet from the sun and quite large
It has an atmosphere and then water and hydrogen, no land
If you weighed 70lbs on Earth, you would weigh 180lbs on Jupiter
It has 28 moons
Saturn
Saturn is the 6th planet from the sun and has large rings
Much like Jupiter, its atmosphere is a giant sea of chemicals
If you weighed 70lbs on Earth you would weight 82lbs on Saturn
It has 30 moons
Uranus, Neptune, and Pluto

Uranus
Uranus is the 7th planet from the sun
It would take many years to fly there on a space ship
It is different from the other planets because it spins on its side
Uranus has 21 moons
Neptune
Neptune is the 8th plant from the sun
It has a giant storm spot much like Jupiter
Neptune has six rings that circle the planet and 8 moons
Pluto
Pluto is the 9th planet from the sun and considered a dwarf planet
because of its extremely small size
If you weigh 70lbs on Earth, you would weigh 4lbs on Pluto
No space ship or probes have ever visited Pluto because it is so far
away so is difficult to know much about its atmosphere
Pluto has 3 moons
Summary
• All of the planets circle the sun at various speeds
• All of the planets are different distances from the sun and each other
• We know little about the planets that are far from us, especially
Uranus, Neptune, and Pluto so we use what we know about Earth to
make educated guess about their atmospheres
• The larger the planet is, the more gravity it has. The planets that are
larger then Earth would make a human weigh more. Those that are
smaller then Earth would make a human weigh less.
• The Sun is the only star in our solar system
• Our solar system is part of a galaxy called the Milky Way Galaxy
• There are an infinite number of galaxies that make up the universe
• There may be other planets in other galaxies in the universe that
can support life, we just do not have the technology to reach them or
research it further as of yet
