Slide 2:

3-4 Interesting Facts

A pretty picture

Length of a year: 88 days

Your age: 67 years old

Mercury-Mercury is the smallest/innermost planet of the solar system

-a person on Mercury would weigh 38% of their weight on Earth

-a Mercury day is 176 Earth days

-it does not possess any moons or rings

VenusType of Planet: Rocky

Composed of: Central Iron Core and a Rocky Mantle (similar to Earth) atmosphere is 96% Carbon Dioxide 3% Nitrogen and small portion of other gases

Number of moons: No moon(s)

Mass relative to Earth: 82%

Length of a year: 225 Days

Your age: K: 27.7 R: 25.5 B: 26.2

Venus- The third brightest object in Earth’s sky after the Sun and Moon- Sometimes referred to as Earth’s sister planet because of the close similarity in size and since it is

the closest planet to Earth- Astronomers know of more than 1,600 volcanoes on the surface of Venus- Days are longer than years on Venus- Pressure is 90x the pressure at sea level on Earth

EarthType of Planet:terrestrial planet

Composed of:the rock mantle consists of Silicon,iron,magnesium,aluminum,oxygen,calcium,sodium,potassium

Number of moons:1

Mass relative to Earth: 1

Length of a year:365 day

Your age:16 years old

Earth-Earth is NOT a perfect sphere. I repeat, NOT a perfect sphere, but a squashed sphere

-the earth was once believed to be the center of the universe

-Earth is the only planet not named after a God

-The earth Is the densest planet in the solar system

-At the equator, you would weigh less than if standing at one of the poles.

MarsMars is a rocky terrestrial planet

Composed of rock and metals, the reddish tint comes from iron (III) oxide.

Mars has 2 moons

Mars has about 11% of Earth’s mass

One mars year is 687 earth days

I, Otto Mao would be about 8.4 years old as a Martian.

MarsMars is named after the Roman god of War.

There are signs that there was once water on Mars and where water is, life also has the possibility to be, so life on Mars may have existed at some point.

One day, Mars will get a ring like Saturn.

Pieces of Mars have fallen to Earth

Asteroid Belt● Sometimes referred to as Minor Planets● Located in the large gap between the orbit of

Mars and the orbit of Jupiter, this region is known as the Asteroid belt

● More than 10,000 have been discovered● A few asteroids have elliptical paths that

bring them inside Mars’ orbit or even inside Earth’s orbit.

● Some are rocky, others rich in iron or carbon

● Scientist hypothesis extinction of Dinosaurs may have been due to large impact of an Asteroid.

Asteroid Belt

JupiterType of Planet: Gas giant

Composed of: primarily composed of hydrogen wuth a quarter of its mass being helium.

Number of moons: at least 69 moons

Mass relative to Earth: 317.8 Earths

Length of a year: 11.862 earth years

Your age: 1.41 years old

JupiterThe Interesting Facts

1. Jupiter is the fourth brightest object in the solar system.2. It is two and a half times more massive than all the other planets in the solar

system combined.3. Jupiter’s moon Ganymede is the largest moon in the solar system.

SaturnType of Planet: Gas giant

Composed of: a core of iron-nickel and rock.

A deep layer of Metallic hydrogen, a intermediate layer of liquid hydrogen, and a gaseous outer layer

Number of moons: 62moons

Mass relative to Earth: 95.159 earths

Length of a year: 29.4571 earth years

Your age: 0.54 years old

Saturn1. Saturn can be seen with the naked eye.( It is bright.)2. Saturn was the Roman god of agriculture.3. Saturn is the flattest planet.

UranusType of Planet: Ice Giant

Composed of: A Hot, dense substance made up of water, methane and ammonia

Number of moons: 27 small moons (known)

Mass relative to Earth: 14.5

Length of a year: 84.01 Earth years

Your age: 0.19 years and 0.18 years

Uranus● It has 13 known rings

○ The inner of which are narrow and dark○ The outer of which are brightly colored

● It rotates on its side

● The planet’s north pole gets 21

years of night-time in winter, 21

years of daytime in summer and 42

years of day and night in the spring

and fall

NeptuneType of Planet: Ice Giant

Composed of: A Hot, dense substance made up of water, methane and ammonia

Number of moons: 13 (known), 1 awaiting confirmation

Mass relative to Earth: 17.1

Length of a year: 164.79 Earth years

Your age: 0.09 years

Neptune● Pluto is sometimes closer to the

sun than Neptune is

● Not visible to the naked eye

● Named after the Roman god of the

sea

● It has crazy winds that can reach

up to 1,996 kph (1,240 mph)

OOrt Cloud

● Theorized by Jan Oort

● Extends from 5,000-100,000 AU’s

● Home to long-period comets

● Never been observed, only a theory

● Contains 0.1-2 trillion comets

● Edge of our solar system

Comets “dirty snowballs”:- a compact chunk of frozen gases and dust- only a few kilometres in diameter- Long period comets in Oort cloud take over 200

years to orbit- Fly into the inner solar system- When a comet is a large distance from the Sun, it

remains totally frozen and is not observable. When it gets near the Sun, it heats up. Some of its gas is vaporized by the heat and some of its dust is released.

- It develops a big gas and dust cloud called a coma. It also develops two tails, a gas tail which points directly away from the Sun and a dust trail, which points away from the Sun but is swept backward along the comet’s orbit.
