Planets of the Solar System
Hilari Hopson
Introduction There are eight major planets in the
solar system, all with their own unique features.
This power point will explain how each of these planets differ.
Mercury Mercury is the innermost
and smallest planet of the solar system
It’s diameter is 4879.4 km It’s temperature ranges
from -173° C to 427° C The atmosphere consists of
some hydrogen, helium, and oxygen
There is no wind, no rings, and no moons on mercury
It’s average distance from the sun is 57,910,000 km
Mercury’s rotation lasts 58 Days, 15.5 Hours
It has an iron core, and a silicate surface
Mercury has a slight magnetic field
Venus Venus is the second planet from the sun It is the hottest and brightest planet It’s diameter is 12,104 km The temperature ranges from -45° C to 464° C It’s atmosphere consists of nitrogen and 97%
carbon dioxide Venus has no moons and no rings It’s distance from the sun is 108,200,000 km It’s retrograde rotation lasts 243 Days, 0.5 Hours Like Mercury, Venus has an iron core and a silicate
surface
Earth Earth is the third planet from the sun It’s 4.6 billion years old and the fifth largest
planet in our solar system Earth has an average diameter of 12,742
kilometers. It’s average temperature is between 5000
and 7000 degrees C. The Earth is made mostly of iron, oxygen,
silicon, magnesium, nickel and sulfur
Mars Mars is the fourth
planet from the sun Diameter is 6794.4
km Temperature ranges
from -140° C to 20° C
Mars has a very thin atmosphere, made mostly of carbon Dioxide
Mars has large canyons, volcanoes, dust storms, sand dunes, polar ice caps and other features similar to those found on Earth.
It has two moons and winds up to 100 km/hr
It’s 227,940,000 km from the sun
Mars is composed of Iron Oxides and Silicates
Jupiter Unlike the rocky planets,
Jupiter is a ball of dense hydrogen, helium, water, nitrogen and other gases over a tiny rocky core.
It’s diameter is 142,984 km
It’s temperature ranges from -163° C to >-121° C
Jupiter's atmosphere is made up of Hydrogen, Helium, Methane
It has winds up to150 m/s and over sixty moons
The average distance from the sun is 778,330,000 km and it’s rotation only takes 9.925 hours
Jupiter has three rings
Saturn Saturn’s diameter is 120,536 km It’s temperature ranges from -191° C to >-130° C Like Jupiter, Saturn’s atmosphere is made up of
hydrogen, helium, and methane There are winds up to Up to 400 m/s and a total of
31 moons Saturn has rings and is composed of hydrogen
and helium It has an extremely strong magnetic field
Uranus Being the seventh planet from the sun, the icy
planet Uranus is a smaller version of Jupiter Uranus takes about 84 years to orbit the sun
while rotating on its side The faint bluish color of the planet is because
the methane gas in the atmosphere absorbs red light and reflects blue light.
It’s diameter is 51,118 km Uranus has sixteen moons and is
2,870,990,000 km away from the sun
Neptune Neptune is the eighth and farthest planet
from the sun Its diameter is 49,572 km Its temperature ranges from -223° C to >-
220° C It has rings and thirteen known moons Neptune’s magnetic field is up to 20 times
its radius Neptune is one of the solar system's gas giants
Conclusion Our Solar System is a mysterious,
beautiful thing. The eight planets in our Solar System
are all different and have their own story to tell.
I hope one day we will be able to travel to these other planets and find new incredible facts about our Solar System.
