Todays best hypothesis: Planet formation in a nutshell

• Earth, Sun, and rest of Solar System formed from cloud of gas and dust ~ 4.6 billion years ago

• Properties of individual planets reflect their proximity to the hot proto-sun

• Some planets have experienced major perturbations and/or collisions

• Comets and asteroids are debris left over from Solar System formation

December 12, 2012 There are four terrestrial planets in our Solar System: Mercury, Venus, Earth, and Mars. The terrestrial planets are also referred to as the inner planets as these planets are the four closest to the Sun. Terrestrial planets are rocky planets. They differ from gas giants, which are the outer most planets.Terrestrial planets are rock and heavy metals. These planets have a cores which is typically iron. Outside the core is a mantle of silicate rock. Terrestrial planets are smaller than the outer planets. Terrestrial planets have varied terrain such as volcanoes, canyons, mountains, and craters.The atmosphere of a terrestrial planet can vary fromcarbon dioxide atmosphere to almost nothing. The most complex atmosphere is our own and a primary reason our planet supports life Photo: Terrestrial Planets (2011) Retrieved from: http://www.universetoday.com/50287/terrestrial-planets / 6.

Comets

• Composed of frozen gases, ice, and dust

• Forms from and orbits the Oort Cloud and Kuiper Bel t

Asteroids

• Small rocky objects

• Diverse population

• Also referred to as minor planets or planetoids

Meteorites

• Four main categories of compositions

• Meteors can be referred to as shooting stars

Satellites

• Man-made

• Approximately 3,000 operating in Earths orbit

What is a minor-planet?

• A minor-planet is anobject in direct orbit around the Sun that is neither a dominant planet nor a comet.

When was minor-plant Shakespeare discovered?

• Edward L. G. Bowell discovered this minor-planet in 1983.

General information on Shakespeare.

• Shakespeare is a small main belt asteroid.

• It belongs to the Koronis family

• Its temperature is -165k (Kevin scale)

• Dimensions unknown

Contrast to Earth

• Earth has a climate

• Earth can sustain life

• Earth is also much larger than Shakespeare

Contrast to other asteroids

• All asteroids are different in size, shape, color, and distance. When compared to Shakespeare they can be different or some may be the same in some aspects.

• Asteroids can be rocky or metallic.

Contrast to other object

• Satellites are man made where Shakespeare is not

• Meteors are consider more of a shooting star and dontalways orbit

What is an exo-planet?

• Exo-planet or extrasolar planet isa planet outside of our Solar System.

When was Kepler-22b discovered?

• It was discovered by NASAs Kepler Space Telescope in 2009 and announced December 5, 2011.

General information on Kepler-22b.

• Its radius is 2.4 times that of Earth

• Its mass and surface composition remain unknown.

• The temperature on the planet is only an estimate of either -11C or 22C.

• Its parent star is Kepler-22, which is in the constellation Cygnus.

Contrast to Earth

• It is 2.4 times the size of Earth

• It looks more green in color where as Earth looks blue.

• It has been said it is the closes resemblance of Earth, but still is speculation.

Contrast to asteroids

• Asteroids are much smaller compared to Kepler-22b or Earth.

• Asteroids are rocky and metallic. Kepler-22b may be a gas planet or a ocean planet.

Contrast to other objects.

• Comets are made up of frozen gas, ice, and dust

• Moons are like small planets that orbit the main planet.
