The Solar System formed...

4.6 Billion Years Ago

Two main categories of planets and their definitions...

Terrestrial Characteristics:

  • Rocky surfaces
  • Higher density
  • Smaller size
  • Few or no moons
  • No rings

Jovian Characteristics:

  • Very large
  • Lower density
  • Mostly gas and ice
  • Many moons
  • Ring systems

What are asteroids, meteors, and comets usually called?

Small Solar System bodies

100

How did the Moon form?

when a Mars-sized object collided with the young Earth (Giant Impact Hypothesis)

100

What is an ellipse?

An oval-shaped orbit

200

All the objects in the Solar System are held together by...

Gravity

200

Name 5 planets

Mars, Mercury, Earth, Neptune, Jupiter, Uranus, Saturn, Venus

200

What lives in the Oort Cloud and the Kuiper Belt?

Comets

200

What does Earth's shadow cause?

Lunar Eclipses


200

What did Newton tell us about planets?

Their movement

300

Process where dust started to stick together and form other things

Accretion

300

Why are there two different planets?

According to the Nebular Theory, planets formed in different temperature regions of the protoplanetary disk around the young Sun.

300

Where is the asteroid belt located?

Between Mars & Jupiter

300

How do moon phases occur?

Moon's position relative to the Earth and Sun

300

The farther a planet is from the Sun, the longer it takes to complete one orbit.

Kepler's 3rd Law, Law of Harmonies


400

Main Steps to the Nebular Theory

Main Steps:

  • A giant cloud of gas and dust existed in space.
  • Gravity caused the cloud to collapse.
  • The cloud began spinning faster.
  • The Sun formed in the center.
  • Planets formed from the remaining material.
400

What is the surface of a terrestrial planet?

  • Surfaces
    • Solid rock
    • Mountains
    • Volcanoes
    • Impact craters
400

What kind of orbits do Comets have?

Elliptical 

400

Define a Solar and Lunar eclipse

Solar: Sun → Moon → Earth 

Lunar: Sun → Earth → Moon 

400

Closer to the Sun → Moves faster

Farther from the Sun → Moves slower

Kepler's 2nd Law, Law of Equal Areas

500

The 3 other Solar System bodies are...

Oort Cloud, Kuiper Belt, Asteroid Belt

500

Surface of a Jovian planet?

No solid outer surface that spacecraft can land on

Thick layers of gas and/or ice

500

What is the difference between a meteor, meteoroid, and meteorite?

Meteoroid - debris from asteroid/comets

Meteors - a burnt up meteoroid

Meteorite - Meteors that made it to Earth's surface


500

Which eclipse is more common to see and why?

Lunar, Visible across much of Earth's night side 

500
