Let’s take a trip and I’ll Planet…
The path an object takes through space caused by gravity and momentum
What is its orbit?
Circular depressions resulting from the high velocity impacts of projectiles with larger bodies.
What are craters?
A cloud of gas and dust in space. Provides the material for stars and planets.
What is a nebula?
These planets are small in size, high density, close to the sun, made of rock and metal, with thin atmospheres.
What are the terrestrial planets?
The difference in observed relative position when an object is observed from two different points of view.
What is parallax?
This is the force of attraction between all objects that depends on both distance and mass.
What is gravity?
The line about which a rotating body, such as the Earth, turns.
What is its axis?
Small sand to boulder sized objects that enter Earth’s atmosphere. Often called “Shooting Stars”
What are meteors?
This is the correct order of the stages of the formation of our solar system.
Hint: The stages are: Accretion of Planets, Gravitational Collapse, Fusion, Spinning, Nebula, Flattening.
What is 1. Nebula, 2. Gravitational Collapse, 3. Spinning, 4. Flattening, 5. Fusion, and 6. Accretion of Planets?
These Planets are large, with low densities and thick atmospheres. They are made primarily of gas and ice.
What are the jovian planets (gas giants)?
This is how we know which objects are close and which objects are far in the night sky.
What is parallax (more movement = closer) and Size (bigger = closer)?
A reaction in which lighter atoms join to form heavier atoms. Occurs in stars.
What is fusion?
One complete turn on a planet's axis. On Earth it takes one day.
What is a rotation?
Objects made of rock, metal and ice that orbit the sun but are two small to be called planets.
What are asteroids?
Nebula, Gravitational Collapse and Fusion are essential for making these.
What are stars?
These are the two gases that most of the solar system is made of.
What are hydrogen (75%) and helium (25%)?
These are the things that move around in the night sky.
What are Asteroids, Comets, Meteors, Planets and Moons?
This is the definition of a light year.
What is a unit of measure used in astronomy, the distance light travels in a year, ~6,000,000,000,000 miles?
The slant of a planet's axis relative to its orbital plane. Causes seasons.
What is its tilt?
Rocky, metallic objects held together by frozen gas. Have large irregular orbits.
What are comets?
Out of Accretion of Planets, Gravitational Collapse, Fusion, Spinning, Nebula, and Flattening; these are ONLY required for making planets.
What are Spinning, Flattening and Accretion of Planets?
This is how old we have determined the solar system to be using radioisotope dating.
What is 4.6 billion years old?
These are the things that do NOT move in the night sky.
What are Stars, Galaxies and Nebulae?
This is the name of the planets orbits shape.
What are Elliptical Orbits?
A single orbit of one heavenly body around another. One year on Earth.
What is a revolution?
This is why there are more crater impacts on the moon than on Earth.
What is the Earth has an atmospheric and geologic processes? #themoonisdead
This is why the inner planets are so different from the outer planets.
What is the solar wind blow the lighter material out while gravity holds heavy material close?
or
What is Solar Nebular Theory?
This is a complete list of the kinds of objects in our solar system.
What are the Sun, 8 Planets, 3+ Dwarf Planets, 240+ Moons and Small Bodies (Comets, Asteroids, gas and dust)?
This is why we only see one side of the moon.
What is synchronous rotation?
This is why Pluto was demoted to Dwarf Planet status.
What is it did not clear its neighborhood?
