General Notes on the Planets

• Solar system is made of 8 planets and other objects that orbit the Sun

• The orbits are elliptical, so a planet’s distance from the Sun will vary.

• Movement of a planet around the Sun is the revolution

• The spin of a planet on its axis is its rotation

General Notes on Planets

• Venus and Uranus display retrograde motion, meaning they rotate clockwise instead of counter clockwise

• Uranus is tilted on its side with its axis nearly parallel to the plane of its orbit.

• Four planets closest to the sun are the inner planets (Mercury, Venus, Earth, Mars)

• There is an asteroid belt in between the orbits of Mars and Jupiter

• The planets beyond the asteroid belt are the outer planets

Warm- up (10-6-14)

• Explain the article from the NASA current event.

• What did you think of the article?• Is there anything you can suggest to NASA

about the article?

Outline

• Objectives• Facts about the planets I want you to know!• Atmospheres of Planets

Objectives

• To determine specific facts about individual planets and their satellites

Mercury

• Planet nearest the sun• Shortest orbital period (88 Earth Days)• Smallest planet• Has a magnetic field about 1% as strong as Earth• Heavily cratered (similar to Earth’s moon)

– Mercury’s most abundant landform• Also has smooth surfaces – may have been

formed by lava flowing out of cracks in Mercury’s surface

Mercury

• Turns on its axis every 59 days• Daytime temperatures 400 degrees C

– What does this do to the particles above the surface?

• Night temperatures -200 degrees C• Weak gravity = no atmosphere

Venus

• Earth’s Sister– Similar diameter, mass, gravity

• Weak or nonexistent magnetic field• Rotates from east to west• Rotates slowly on axis, 243 days• Orbits sun in 225 days

– One day is longer than one year on Venus• Thick pale yellow clouds in atmosphere• Surface has volcanic features, faulting, and impact craters• 80% of surface is covered with lava

Venus

• Not sure if volcanic activity is still going on• Oldest crust is 800 million years old• Dense atmosphere

– Mostly carbon dioxide with a little nitrogen– Acts like greenhouse = surface temps 475 degrees

C– Sulfuric acid = yellow clouds

• Surface atmospheric pressure is 90 times greater than on Earth

Mars

• 687 days to orbit the sun• Diameter is half of Earth’s• Gravity is 2/5 that of Earth’s • Weak magnetic field• Similar axis tilt to Earth

– 4 seasons similar to Earth• Year is twice as long as Earth year (what does this do to

the seasons?)• Thin atmosphere

– 95% Carbon dioxide and 5% nitrogen and argon

Mars

• Thin atmosphere, so pressure is less than 1% that of Earth

• Polar ice caps – most likely water ice covered by frozen CO2

• Temperature difference between poles and soil = strong winds and swirling dust storms

• Largest volcano = Olympus Mons– Not related to plate motions

• Valles Marineris – canyon system as long as US• What happened to the water that once covered the

surface of Mars?

Jupiter

• Takes 11.9 years to orbit the sun• Rotates faster than any other planet (about 10 hours)• Largest planet – more than twice total mass of all other

planets combined• Strongest magnetic field• Interaction between solar wind and magnetic field causes

auroras• Jupiter radiates 2x as much heat into space compared to

what it receives– May come from original heat of formation and from contraction

due to gravity

Jupiter

• Great Red Spot– One of several spots– Photos indicate spots might be calm areas rotating

slowly in violent atmosphere• No thick, dense clouds• High temperatures and pressures in upper

atmosphere• Deep atmosphere is convective• What does this mean?

Saturn

• 30 Earth years to complete one orbit• Turns on its axis about every 10 hours• Colored zones and belts – areas of rising and sinking gas• Fewer belts than Jupiter• Lowest density – it could float!• Has source of internal heat – radiates out more heat

than it receives• Weaker magnetic field than Jupiter but stronger than

Earth• Rings are made of ice with some rock – remains of

asteroids, comets, small moons crushed by gravity

Uranus

• 84 years to complete one orbit• Average surface temp. is -200 degrees C• Turns on axis once every 17.2 hours• Axis of rotation is parallel to orbital plane

– It is tipped on its side!– Why did this happen?

• Magnetic field is present but is not tipped on its side– Difference is 60 degrees– Difference causes magnetic field to trace spiral pattern in

solar wind as planet rotates• Turquoise color due to methane gas

Neptune

• Rotates on axis 16.1 hours and takes 165 years to orbit sun

• Magnetic axis is tipped 47 degrees compared to axis of rotation– Also offset from the planet’s center– Scientists think motions of conductive material (maybe

water) generate the magnetic field• Harsh winds 2000 km/hr• Atmosphere is mostly hydrogen, some helium, and

small amount of methane

Neptune and Pluto

• Neptune and Pluto cross orbital paths, meaning they switch being closer to the sun

• Pluto is smaller than seven of the solar system’s moons, even Earth’s moon!

• Pluto has a moon Charon that is about half it’s size

Apparent Magnitude

• Measure of how bright a star appears to be to an observer on Earth

• Lower the magnitude number, the brighter the star is

• Faintest stars that are visible are sixth-magnitude stars

• Each magnitude differs from the next by a factor of 2.5– First magnitude star is about 2.5 times brighter than a

second magnitude star

Distance

• Astronomical Unit (AU) – average distance between the Earth and the sun– 150 million kilometers

• Nearest star to Earth is Proxima Centauri but is still more than 2.5 kilometers away if the Earth and Sun were dots 1 cm apart

• Light Year – distance that a ray of light travels in one year– 9.5 trillion kilometers

• Proxima Centauri is about 4.2 light years away from Earth

• Parallax – change in object’s direction due to a change in observer’s position– at different times of the year a nearby star doesn’t seem to be in

exactly the same position against the backdrop of stars
